修改Index视图如下：
@model IEnumerable<MvcApplicationStudy.Models.UserInfo>
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<script src="~/Scripts/jquery-1.7.1.js"></script>
<script type="text/javascript">
$(function () {
var dels = $(".del");
for (var i = 0; i < dels.length; i++) {
dels[i].onclick = function () {
return confirm("您确定要删除吗？");
};
}
});
</script>
<title>Index</title>
</head>
<body>
<div>
<table>
<tr><th>编号</th><th>用户名</th><th>密码</th><th>时间</th><th>详细</th><th>删除</th><th>修改</th></tr>
@* @foreach(var userInfo in ViewBag.Model){
<tr>
<td>@userInfo.ID</td>
<td>@userInfo.UserName</td>
<td>@userInfo.UserPwd</td>
<td>@userInfo.RegTime</td>
<td>详细</td>
<td>删除</td>
<td>修改</td>
</tr>
}*@
@foreach(var item in Model){
<tr>
<td>@Html.DisplayFor(modelItem=>item.ID)</td>
<td>@Html.DisplayFor(modelItem=>item.UserName)</td>
<td>@Html.DisplayFor(modelItem=>item.UserPwd)</td>
