在这里插入图片描述

JdbcUtil.cs代码：

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
/// <summary>
/// 连接数据库---工具类
/// </summary>
namespace WebApplication5.Commons
{
    public class JdbcUtil
    {
        //与数据库连接，从Web.config中读取参数
        public static string MyConn = ConfigurationManager.AppSettings["connectionstring"];

        public static SqlConnection conn = new SqlConnection(MyConn);
        /// <summary>
        /// 查询数据，查询结束后手动关闭数据库连接
        /// </summary>
        /// <param name="sql"></param>
        /// <returns></returns>
        public SqlDataReader select(string sql)
        {
            SqlDataReader reader = null;
            conn.Open();
            SqlCommand comm = new SqlCommand(sql, conn);
            reader = comm.ExecuteReader(System.Data.CommandBehavior.CloseConnection);
            return reader;
        }
        //删除、添加、更改
        public static int ExecuteUpdate(string sql)
        {
            int result = 0;
            conn.Open();
            SqlCommand comm = new SqlCommand(sql, conn);
            result = comm.ExecuteNonQuery();
            conn.Close();
            return result;
        }
        //单条数据的查询
        public static Object ExecteOnlyOneVaule(string sql)
        {
            Object obj = null;
            conn.Open();
            SqlCommand comm = new SqlCommand(sql, conn);
            obj = comm.ExecuteScalar();
            conn.Close();
            return obj;
        }

    }
}

3）在数据库中新建表
use Demo;
create table Student (
Sid int primary key IDENTITY(1,1) ,
Name varchar(50) not null,
Sex varchar(2) not null,
Birthday datetime,
ClassName varchar(30) ,
ProfessionalName varchar(30),
);
在这里插入图片描述
4）在VS2019中建立对应的实体类

4、简单的实现查询所有数据功能

1） DAL层（DAL文件夹中）新建项“StudentDAL.cs”

using System;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
using WebApplication5.Commons;
using WebApplication5.Models;

namespace WebApplication5.DAL
{
    public class StudentDAL
    {
        /// <summary>
        /// 查询所有的数据--根据搜索参数
        /// </summary>
        /// <returns></returns>
        public List<Student> GetAll(string key)
        {
            List<Student> studentList = new List<Student>();
            JdbcUtil jdbcUtil = new JdbcUtil();

            string query = "select * from Student where 1=1 ";
            if (!string.IsNullOrEmpty(key))//有参数输入参数，进行搜索的功能
            {
                query += string.Format(" and (  Name like '%{0}%' or ClassName like '%{0}%' or ProfessionalName like '%{0}%' ) ", key);
            }
            SqlDataReader data=jdbcUtil.select(query);
            while (data.Read())//将数据读取到,存到list集合中
            {
                Student student = new Student();
                student.Sid = (int)data["Sid"];
                student.Name = (string)data["Name"];
                student.Sex = (string)data["Sex"];
                student.Birthday = (DateTime)data["Birthday"];
                student.ClassName = (string)data["ClassName"];
                student.ProfessionalName = (string)data["ProfessionalName"];
                studentList.Add(student);
            }
            JdbcUtil.conn.Close();//关闭数据库的连接
            return studentList;
        }
    }
}

2） BLL层新建项“StudentBLL.cs”
在这里插入图片描述

3） Controller层新建 " StudentController",

1)选择添加“控制器
在这里插入图片描述

在这里插入图片描述
2）在StudentController中生成相应的视图
i)代码

using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using WebApplication5.BLL;
using WebApplication5.Commons;
using WebApplication5.Models;

namespace WebApplication5.Controllers
{
    public class StudentController : Controller
    {
        private StudentBLL studentBLL = new StudentBLL();
        // GET: Student
        public ActionResult Index()
        {
            return View();
        }
        /// <summary>
        /// 没有加layui表格的数据展示
        /// </summary>
        /// <returns></returns>
        public ActionResult GetAll()
        {
            string key = "";
           List<Student> students=  studentBLL.GetAll(key);
            return View(students);
        }
      }
 }

ii)操作
在这里插入图片描述

在Views下自动生成文件夹Student及“GetAll.cshtml”，代码自动生成

@model IEnumerable<WebApplication5.Models.Student>

<p>
    @Html.ActionLink("Create New", "Create")
</p>
<table class="table">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.Sid)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Name)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Sex)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Birthday)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.ClassName)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.ProfessionalName)
        </th>
        <th></th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.Sid)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Name)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Sex)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Birthday)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ClassName)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ProfessionalName)
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
        </td>
    </tr>
}

</table>

3）效果图
在这里插入图片描述

5、使用Layui改变页面样式

1、下载layui并导入项目
在这里插入图片描述

压缩包解压，然后将文件夹复制到项目里
在这里插入图片描述
2、修改Views/Shared/_Layout.cshtml

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>后台管理系统 - My ASP.NET Application</title>
    <link href="~/Content/Site.css" rel="stylesheet" type="text/css" />
    <link rel="stylesheet" href="~/layui/css/layui.css">
    <link href="~/Content/bootstrap.min.css" rel="stylesheet" type="text/css" />
    <script src="~/Scripts/modernizr-2.8.3.js"></script>
</head>
<body class="layui-layout-body">
    <div class="layui-layout layui-layout-admin">
        <div class="layui-header">
            <div class="layui-main">
                <div class="layui-logo">后台管理系统</div>
                <ul class="layui-nav" style="position: fixed; top: 0; right: 0; background: none;" lay-filter="nav-top">
                    <li class="layui-nav-item">      
                        <dl class="layui-nav-child">
                            <dd><a href="javascript:;">退出</a></dd>
                        </dl>
                    </li>
                </ul>
            </div>
        </div>
        <div class="layui-side layui-bg-black">
            <div class="layui-side-scroll">
                <ul class="layui-nav layui-nav-tree" lay-filter="navSlide">
                    @Html.Raw(ViewBag.MenuItems)
                   
                </ul>
            </div>
        </div>
        <div class="layui-body">
            <div class="layui-fluid">
                @RenderBody()
                @RenderSection("content", false)
            </div>
        </div>
    </div>
</body>
</html>

3、新建controller（BaseController），----初始化_Layout.cshtml中的值，完成侧边栏

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web;
using System.Web.Mvc;
//进行初始化，其他的Controller是基于此进行
namespace WebApplication5.Controllers
{
    public class BaseController : Controller
    {  
        protected override void Initialize(System.Web.Routing.RequestContext requestContext)
        {
            base.Initialize(requestContext);
            SetMenu();
        }
        private void SetMenu()
        {
            StringBuilder sb = new StringBuilder();

            sb.AppendFormat("<li class=\"layui-nav-item {0}\">", "aaaa");
            sb.AppendFormat("<a class='layui-icon {0}' href=\"{1}\">&nbsp&nbsp{2}</a>", "layui-icon-menu-fill", "/Student/Index", "首页");//设置好路由，方便跳转页面
            sb.AppendFormat("</li>");

            sb.AppendFormat("<li class=\"layui-nav-item {0}\">", " ");
            sb.AppendFormat("<a class='layui-icon {0}' href=\"{1}\">&nbsp&nbsp{2}</a>", "layui-icon-set", "/Student/GetAll", "学生管理");
            sb.AppendFormat("</li>");

            sb.AppendFormat("<li class=\"layui-nav-item {0}\">", " ");
            sb.AppendFormat("<a class='layui-icon {0}' href=\"{1}\">&nbsp&nbsp{2}</a>", "layui-icon-user", "/Student/ShowDate", "学生管理w");
            sb.AppendFormat("</li>");
            ViewBag.MenuItems = sb.ToString();
        }
    }
}

4、其他controller 继承BaseController。
5、在StudentController中新建一个方法返回一个页面，使用Layui改变表格整体样式，可以先复制官网范例，然后修改css路径、JS 路径。
6、在StudentController中创建一个方法返回Json数据，在5、的页面中使用该url。
7、数据显示时，生日日期显示有误，需要改变其格式。
（思路）新建一个类JsonNetResult 继承JsonResult，重写ExecuteResult()方法，从而改变日期格式。

四、代码

1、Commons层

JsonNetResult

using Newtonsoft.Json;
using Newtonsoft.Json.Converters;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

/// <summary>
/// 在使用json 改变数据格式时，对 日期进行修改（重写 ExecuteResult方法）
/// </summary>
namespace WebApplication5.Commons
{
    public class JsonNetResult : JsonResult
    {
        public object Data { get; set; }
        public string DateTimeFormat { get;  set; }

        public JsonNetResult()
        {
        }

        public JsonNetResult(object dat,JsonRequestBehavior jsonRequest)
        {
            this.Data = dat;
            base.JsonRequestBehavior = jsonRequest;
            this.DateTimeFormat = "yyyy年MM月dd日";
        }
        public override void ExecuteResult(ControllerContext context)
        {
        
            HttpResponseBase response = context.HttpContext.Response;

            response.ContentType = "application/json";
            if (ContentEncoding != null)
                response.ContentEncoding = ContentEncoding;
            if (Data != null)
            {
              /*  JsonTextWriter writer = new JsonTextWriter(response.Output) { Formatting = Formatting.Indented };
                JsonSerializer serializer = JsonSerializer.Create(new JsonSerializerSettings());
                serializer.Serialize(writer, Data);
                writer.Flush();*/

                IsoDateTimeConverter isoDateTimeConverter = new IsoDateTimeConverter();
                //设置日期格式
                isoDateTimeConverter.DateTimeFormat = DateTimeFormat;
                //序列化
                string jsonResult = JsonConvert.SerializeObject(this.Data, isoDateTimeConverter);
                response.Write(jsonResult);
            }
        }

    }
}

2、DAL层

StudentDAL

using System;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
using WebApplication5.Commons;
using WebApplication5.Models;

namespace WebApplication5.DAL
{
    public class StudentDAL
    {
        /// <summary>
        /// 查询所有的数据--根据搜索参数
        /// </summary>
        /// <returns></returns>
        public List<Student> GetAll(string key)
        {
            List<Student> studentList = new List<Student>();
            JdbcUtil jdbcUtil = new JdbcUtil();

            string query = "select * from Student where 1=1 ";
            if (!string.IsNullOrEmpty(key))//有参数输入参数，进行搜索的功能
            {
                query += string.Format(" and (  Name like '%{0}%' or ClassName like '%{0}%' or ProfessionalName like '%{0}%' ) ", key);
            }
            SqlDataReader data=jdbcUtil.select(query);
            while (data.Read())//将数据读取到,存到list集合中
            {
                Student student = new Student();
                student.Sid = (int)data["Sid"];
                student.Name = (string)data["Name"];
                student.Sex = (string)data["Sex"];
                student.Birthday = (DateTime)data["Birthday"];
                student.ClassName = (string)data["ClassName"];
                student.ProfessionalName = (string)data["ProfessionalName"];
                studentList.Add(student);
            }
            JdbcUtil.conn.Close();//关闭数据库的连接
            return studentList;
        }




        /// <summary>
        /// 分页--数据
        /// </summary>
        /// <param name="key"></param>
        /// <param name="page"></param>
        /// <returns></returns>
        public List<Student> GetDateByPage(string key,Page page)
        {
            List<Student> studentList = new List<Student>();
            JdbcUtil jdbcUtil = new JdbcUtil();

            string query = string.Format("select * from(select *, ROW_NUMBER()  OVER(order by Sid) as RowId from Student) as b  where  RowId between {0} and {1} ", page.PageSize * (page.PageNum - 1) + 1, page.PageSize * page.PageNum);//RowId between {0} and {1} 。 范围[start,end]，start从1开始。如 between 2 and  4==>2、3、4

            if (!string.IsNullOrEmpty(key))//有参数输入参数，进行搜索的功能
            {
                query = string.Format("select * from(select*, ROW_NUMBER() OVER(order by Sid) as RowId from Student where ( Name like '%{0}%' or ClassName like '%{0}%' or ProfessionalName like '%{0}%') ) as b  where RowId between {1} and {2} ", key, page.PageSize * (page.PageNum - 1) + 1, page.PageSize * page.PageNum);
            }
            SqlDataReader data = jdbcUtil.select(query);
            while (data.Read())//将数据读取到,存到list集合中
            {
                Student student = new Student();
                student.Sid = (int)data["Sid"];
                student.Name = (string)data["Name"];
                student.Sex = (string)data["Sex"];
                student.Birthday = (DateTime)data["Birthday"];
                student.ClassName = (string)data["ClassName"];
                student.ProfessionalName = (string)data["ProfessionalName"];
                studentList.Add(student);
            }
            JdbcUtil.conn.Close();//关闭数据库的连接
            return studentList;
        }




        /// <summary>

            var IsExitSid = JdbcUtil.ExecteOnlyOneVaule(query);//调用方法，查看该数据是否存在
            if (IsExitSid != null)
            {
                return true;//已存在 该 id
            }
            else { return false; }
        }

3、BLL层

StudentBLL

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using WebApplication5.DAL;
using WebApplication5.Models;

namespace WebApplication5.BLL
{
    public class StudentBLL
    {
        private StudentDAL studentDAL = new StudentDAL();
        public List<Student> GetAll(string key)
        {
            return studentDAL.GetAll(key);
        }
        public List<Student> GetDateByPage(string key, Page page)
        {
            return studentDAL.GetDateByPage(key, page);
        }

        public bool SelBySid(int ss)
        {
            return studentDAL.SelBySid(ss);
        }

        public bool AddStudent(Student student)
        {
            return studentDAL.AddStudent(student);
        }


        public bool EditStudent(Student student)
        {
            return studentDAL.EditStudent(student);
        }


        public bool DeleteStudent(int sid)
        {
            return studentDAL.DeleteStudent(sid);
        }
    }
}

4、Controllers层

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

//分页 参数
namespace WebApplication5.Models

    }
}

（2）Student

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
