第一步：在Model中写好查询，删除，修改，添加方法，用sql_link类
using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace MvcApplication2.Models { public class InfoBf { private MydbDataContext _Context = new MydbDataContext(); //查询 public List<student> Select() { return _Context.student.ToList(); } //查询出一条数据修改使用 public student Select(string sno) { var query = _Context.student.Where(p=>p.sno==sno); if (query.Count()>0) { return query.First(); } return null; } //添加 public void Insert(string sno,string sname,string ssex,DateTime sbirthdy,string @class) { student data = new student { sno = sno, sname = sname, ssex = ssex, sbirthdy = sbirthdy, @class = @class }; _Context.student.InsertOnSubmit(data); _Context.SubmitChanges(); } //删除 public void Delete(string sno) { var query = _Context.student.Where(p=>p.sno==sno); if (query.Count()>0) { student data = query.First(); _Context.student.DeleteOnSubmit(data); _Context.SubmitChanges(); } } //修改 public void Update(string sno, string sname, string ssex, DateTime sbirthdy, string @class) { var query = _Context.student.Where(p => p.sno == sno); if (query.Count()>0) { student data = query.First(); data.sno = sno; data.sname = sname; data.ssex = ssex; data.sbirthdy = sbirthdy; data.@class = @class; _Context.SubmitChanges(); } } } }
第二步：添加控制器，一个控制器控制一个视图
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using MvcApplication2.Models; namespace MvcApplication2.Controllers { public class HomeController : Controller { // // GET: /Home/ public ActionResult Index() { ViewBag.Data = new InfoBf().Select(); return View(); } //显示添加界面 public ActionResult Add() { return View(); } public ActionResult Insert(string sno,string sname,string ssex,DateTime sbirthdy,string @class) { new InfoBf().Insert(sno,sname,ssex,sbirthdy,@class); return RedirectToAction("Index"); } //显示修改界面 public ActionResult Exit(string id) { student data=new InfoBf().Select(id); ViewBag.Data = data; return View(); } //更新至数据库 public ActionResult Update(string sno,string sname,string ssex,DateTime sbirthdy,string @class) { new InfoBf().Update(sno,sname,ssex,sbirthdy,@class); return RedirectToAction("Index"); } //删除结束直接更新至数据库 public ActionResult Delete(string id) { new InfoBf().Delete(id); return RedirectToAction("Index"); } } }
第三部：在每一个控制器下添加视图。
这是Index视图
@using MvcApplication2.Models; @using MvcApplication2.Controllers； @{ Layout = null; } <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <title>Index</title> </head> <style type="text/css"> .tbhead { background-color:navy; text-align:center; font-weight:bold; } .tbrow { background-color:#FFFFCC; text-align:center; } </style> <body> <div> <table width="100%" cellpadding="5" cellspacing="1" bgcolor="blue" border ="0"> <tr class="tbhead"> <td>学号</td> <td>姓名</td> <td>性别</td> <td>年龄</td> <td>班级</td> <td>操作</td> </tr> @{ List<student> list=ViewBag.Data as List<student>; foreach(student data in list) { <tr class="tbrow"> <td>@data.sno</td> <td>@data.sname</td> <td><img src="@("images/girl.png")"/></td> <td>@data.sbirthdy</td> <td>@(data.@class)</td> <td> <a href="/Home/Exit/@data.sno">修改</a> <a onclick="return confirm(‘确认要删除 @data.sname 吗？‘)" href="/Home/Delete/@data.sno">删除</a> </td> </tr> } } </table> <a href="/Home/Add">添加人员</a> </div> </body> </html>
这是添加视图
@using MvcApplication2.Models; @using MvcApplication2.Controllers;@{ Layout = null; } <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <title>Add</title> </head> <body> <div> <form id="f1" name="f1" action="/Home/Insert"> <h1> 添加人员</h1> <div> @*学号: <input name="sno" id="sno" type="text"/><br/> 姓名：<input name="sname" id="sname" type="text" /><br/> 性别：<input name="ssex" id="ssex" type="text" /><br/> 年龄：<input name="sbirthdy" id="sbirthdy" type="text" /><br/> 班级：<input name="class" id="class" type="text" /><br/>*@ 学号: <input name="sno" id="sno" type="text"/><br/> 姓名：<input name="sname" id="sname" type="text" /><br/> 性别：<input name="ssex" id="ssex" type="radio"value="男" checked="checked"/ >男<input name="ssex" id="ssex1" type="radio" value ="女" />女<br/> 年龄：<input name="sbirthdy" id="sbirthdy" type="text"/><br/> 班级：<input name="class" id="class" type="text" /><br/> <input id="Submit1" type="submit" value="更新" /> </div> </form> </div> </body> </html>
这是修改视图
@using MvcApplication2.Models; @using MvcApplication2.Controllers; @{ Layout = null; } <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <title>Exit</title> </head> <body> <div> <form id="f1" name="f1" action="/Home/Update"> <h1> 修改人员</h1> <div> @{student data= ViewBag.Data as student; if (data!=null) { <text> 学号: <input name="sno" id="sno" type="text"value="@data.sno" /><br/> 姓名：<input name="sname" id="sname" type="text"value="@data.sname" /><br/> 性别：<input name="ssex" id="ssex" type="text" value="@data.ssex" /><br/> 年龄：<input name="sbirthdy" id="sbirthdy" type="text" value="@data.sbirthdy" /><br/> 班级：<input name="class" id="class" type="text" value="@(data.@class)" /><br/> <input id="Submit1" type="submit" value="更新" /> </text> } } </div> </form> </div> </body> </html>
web MVC程序开发增删改查参考代码。思路是面向对象思想，以及在HTML代码中嵌入C#代码
