1.创建实体
2、创建一个UserInfo的控制器
3、查询数据
code
public IList<UserInfo> userInfoList { get; set; }
DemoEntities demoEntities = new DemoEntities();//创建EF上下文
public ActionResult Index()
{
userInfoList = demoEntities.Set<UserInfo>().ToList();
ViewBag.userInfoList = userInfoList;
return View();
}view
@{
Layout = null;
}
@using MVCCRUDAPI.Models;
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<table>
<tr><td>用户名</td><td>密码</td><td>年龄</td><td>邮箱</td><td>备注</td><td>添加时间</td><td>操作</td></tr>
@foreach (UserInfo userInfo in ViewBag.userInfoList)
{
<tr><td>@userInfo.UserName</td><td>@userInfo.UserPwd</td><td>@userInfo.Age<td>@userInfo.Email</td><td>@userInfo.Remark</td><td>@userInfo.RegTime</td><td><a href="/UserInfo/Edit/@userInfo.Id">编辑</a> <a href="javascript:void(0)" onclick="del(@userInfo.Id)">删除</a></td></tr>
}
</table>
</body>
</html>数据展示
3、添加数据
code
public ActionResult Add()
{
return View();
}
[HttpPost]
public ActionResult Add(UserInfo userInfo)
{
if (!ModelState.IsValid)
{
return Content("error");
}
userInfo.RegTime = DateTime.Now;
demoEntities.UserInfo.Add(userInfo);
demoEntities.SaveChanges();
return Content("ok");
}view
@{
Layout = null;
}
@model MVCCRUDAPI.Models.UserInfo
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>添加</title>

<script>
function success(data) {
if (data == "ok") {
alert("添加成功");
window.location.href = "/UserInfo/Index";
}
else if (data == "error") {
alert("参数提交失败");
}
}
</script>
</head>
<body>
<div>
@using (Ajax.BeginForm("add", "UserInfo", new AjaxOptions { HttpMethod = "post", OnSuccess = "success" }))
{
<div>
@Html.LabelFor(u => u.UserName)
</div>
<div>
@Html.TextBoxFor(u => u.UserName)
</div>
<div>
@Html.LabelFor(u => u.UserPwd)
</div>
<div>
@Html.PasswordFor(u => u.UserPwd)
</div>
<div>
@Html.LabelFor(u => u.Email)
</div>
<div>
@Html.TextBoxFor(u => u.Email)
</div>
<div>
@Html.LabelFor(u => u.Age)
</div>
<div>
@Html.TextBoxFor(u => u.Age)
</div>
<div>
@Html.LabelFor(u => u.Remark)
</div>
<div>
@Html.TextAreaFor(u => u.Remark)
</div>
<br />
<input type="submit" value="添加" /> <a href="/UserInfo/Index">返回</a>
}
</div>
</body>
</html>4、更新数据
code
UserInfo userInfo = new UserInfo();
public ActionResult Edit(int id)
{
userInfo = demoEntities.Set<UserInfo>().Where(u => u.Id == id).FirstOrDefault();
return View(userInfo);
}
[HttpPost]
public ActionResult Edit(UserInfo userInfo)
{
if (!ModelState.IsValid)
{
return Content("error");
}
demoEntities.UserInfo.Attach(userInfo);//对象添加到EF管理容器中
demoEntities.Entry(userInfo).State = EntityState.Modified;
demoEntities.SaveChanges();
return Content("ok");
}view
@model MVCCRUDAPI.Models.UserInfo
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>编辑</title>
</head>
<body>
<script src="~/Scripts/jquery-1.8.2.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>
<script>
function success(data) {
if (data == "ok") {
alert("编辑成功");
window.location.href = "/UserInfo/Index";
}
else if (data == "error") {
alert("参数提交失败");
}
}
</script>
@using (Ajax.BeginForm("Edit", "UserInfo", new AjaxOptions { OnSuccess = "success", HttpMethod = "post" }))
{
@Html.HiddenFor(model => model.Id)
<div>
@Html.LabelFor(model => model.UserName)
</div>
<div>
@Html.EditorFor(model => model.UserName)
</div>
<div>
@Html.LabelFor(model => model.UserPwd)
</div>
<div>
@Html.EditorFor(model => model.UserPwd)
</div>
<div>
@Html.LabelFor(model => model.Age)
</div>
<div>
@Html.EditorFor(model => model.Age)
</div>
<div>
@Html.LabelFor(model => model.Email)
</div>
<div>
@Html.EditorFor(model => model.Email)
</div>
<div>
@Html.LabelFor(model => model.Remark)
</div>
<div>
@Html.TextAreaFor(u => u.Remark)
</div>
@Html.HiddenFor(model => model.RegTime)
<p>
<input type="submit" value="保存" /> <a href="/UserInfo/Index">返回</a>
</p>
}
</body>
</html>5、删除数据
code
public ActionResult Delete(int id)
{
userInfo.Id = id;
demoEntities.UserInfo.Attach(userInfo);//对象添加到EF管理容器中
demoEntities.Entry(userInfo).State = EntityState.Deleted;
demoEntities.SaveChanges();
return Content("ok");
}view
<script>
function del(id) {
if (confirm("确定删除吗?")) {
$.post("/UserInfo/Delete/" + id, null,
function success(data) {
if (data == "ok") {
alert("删除成功");
window.location.href = "/UserInfo/Index";
}
else {
alert("参数错误");
}
})
}
}
</script>
