MVC人员管理系统

基本都要使用C控制器中的两个action来完成操作，一个用于从主界面跳转到新页面、同时将所需操作的数据传到新界面，另一个则对应新界面的按钮，用于完成操作、将数据传回主界面以及跳转回主界面。根据不同情况使用不同的传值方法。

在M模型层中定义所需的LinQ操作

1.查

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<%@ Import Namespace="Mvc_staff.Models" %>
<!DOCTYPE html>

<html>
<head runat="server">
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    
    <table style="background-color:blue;100%;">
        <tr style="color:white;text-align:center">
            <td>用户名</td>
            <td>密码</td>
            <td>昵称</td>
            <td>性别</td>
            <td>生日</td>
            <td>民族</td>
            <td>操作</td>
        </tr>
        <% List<Users> ulist = new UsersData().SelectAll();
           foreach (Users us in ulist)
           { 
            %>
        <tr style="background-color:white;text-align:center;">
            <td><%=us.Username %></td>
            <td><%=us.Password %></td>
            <td><%=us.Nikename %></td>
            <td><%=us.Sex.Value?"男":"女" %></td>
            <td><%=us.Birthday.Value.ToString("yyyy年MM月dd日") %></td>
            <td><%=us.Nation1.NationName %></td>
            <td>
                <a href="/Home/Update/<%=us.Ids %>">修改</a>
                <a href="Home/Delete/<%=us.Ids %>">删除</a>
            </td>
        </tr>
        <%} %>
    </table>
    <input type="button" value="添加" onclick="window.open('Home/InsertMain')" />
    
</body>
</html>
展示页

2.删

在C层添加动作

public ActionResult Delete(string id)
        {
            bool ok = new UsersData().delete(id);

            Session["deleteok"]=ok;
            return RedirectToAction("Index");
        }
删除动作

3.添加

View中提交元素，表单元素使用form表单提交，按钮的使用submit，点击submit的时候会提交所在form表单中的数据，在控制器C中获取元素，在模型层M的写法，在C中调用。

        public ActionResult InsertSub(string usersname, string password, string nickname, string sex, string birthday, string nation)

            us.Username = usersname;
            us.Password = password;
            us.Nikename = nickname;
            us.Sex = Convert.ToBoolean(sex);
            us.Birthday = Convert.ToDateTime(birthday);
            us.Nation=nation;

            bool isok = new UsersData().insert(us);
            Session["Insertok"] = isok;

            return RedirectToAction("Index");
        }
添加动作

4.修改

同添加，需要两个action支持，一个主页面打开修改页面，一个修改按钮确定修改返回主页面

从控制器传值到View使用ViewBag.包名=数据源。

View中<%Users u=ViewBag.包名 as User; %>

系统自生成的Users u 有可能缺少部分内容

form表单中的action路径 action="/home/update"
