这篇文章主要为大家详细介绍了MVC4制作网站教程，修改用户组功能的实现代码，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

一、用户
二、用户组
2.1浏览用户组
2.2添加用户组
2.3修改用户组
首先打开【UserGroupController】，修改[Edit(int Id)] Action

				?

									/// <summary>

									 /// 修改用户组

									 /// </summary>

									 /// <param name="Id">用户组Id</param>

									 /// <returns></returns>

									 [AdminAuthorize]

									 public ActionResult Edit(int Id)

									 {

									 userGroupRsy = new UserGroupRepository();

									 var _userGroup = userGroupRsy.Find(Id);

									 return View(_userGroup);

									 }

右键添加强类型视图，并修改视图代码（与添加用户组类似）

				?

									@model Ninesky.Models.UserGroup

									@{

									 ViewBag.Title = "修改用户组";

									 Layout = "~/Views/Layout/_Manage.cshtml";

									}

									<div class="left">

									 <div class="top"></div>

									 左侧列表

									</div>

									<div class="split"></div>

									<div class="workspace">

									 <div class="inside">

									 <div class="notebar">

									 <img alt="" src="~/Skins/Default/Manage/Images/UserGroup.gif" />修改用户组资料

									 </div>

									 @using (Html.BeginForm("Eidt","UserGroup"))

									 {

									 @Html.ValidationSummary(true)

									 <fieldset>

									 <legend>用户组资料</legend>

									 @Html.HiddenFor(model => model.UserGroupId)

									 <ul>

									  <li>

									  <div class="editor-label">

									  @Html.LabelFor(model => model.Type)

									  </div>

									  <div class="editor-field">

									  @Html.DisplayTextFor(model => model.Type)

									  </div>

									  </li>

									  <li>

									  <div class="editor-label">

									  @Html.LabelFor(model => model.Name)

									  </div>

									  <div class="editor-field">

									  @Html.EditorFor(model => model.Name)

									  @Html.ValidationMessageFor(model => model.Name)

									  </div>

									  </li>

									  <li>

									  <div class="editor-label">

									  @Html.LabelFor(model => model.Description)

									  </div>

									  <div class="editor-field">

									  @Html.EditorFor(model => model.Description)

									  @Html.ValidationMessageFor(model => model.Description)

									  </div>

									  </li>

									  <li>

									  <div class="editor-label">

									  </div>

									  <div class="editor-field">

									  <input type="submit" value="保存" />

									  </div>

									  </li>

									 </ul>

									 </fieldset>

									 }

									 </div>

									</div>

									<div class="clear"></div>

									@section Scripts {

									 @Scripts.Render("~/bundles/jqueryval")

									}

修改处理Action[Eidt(UserGroup userGroup)]

[HttpPost]

[AdminAuthorize]

public ActionResult Eidt(UserGroup userGroup)

{

userGroupRsy = new UserGroupRepository();

var _userGroup = userGroupRsy.Find(userGroup.UserGroupId);

if (_userGroup == null)

{

Error _e = new Error { Title = "用户组不存在", Details = "修改用户时发生错误，修改的用户组不存在。", Cause = "该用户组已被其他管理员删除", Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("List", "UserGroup") + "'>用户组列表</a></li>") };

return RedirectToAction("ManageError", "Prompt", _e);

}

_userGroup.Name = userGroup.Name;

_userGroup.Description = userGroup.Description;

if (userGroupRsy.Update(_userGroup))

{

Notice _n = new Notice { Title = "修改成功", Details = "成功修改了用户组信息", DwellTime = 3, NavigationName = "用户组列表", NavigationUrl = Url.Action("List", "UserGroup") };

return RedirectToAction("ManageNotice", "Prompt", _n);

}

else

{

Error _e = new Error { Title = "更新数据失败", Details = "修改用户组信息时修改的信息未能保存到数据库。", Cause = Server.UrlEncode("<li>您并未更改用户组信息。</li><li>数据库未知错误。</li>"), Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("List", "UserGroup") + "'>用户组列表</a></li><li>重新<a href='" + Url.Action("Edit", "UserGroup", new { id = userGroup.UserGroupId }) + "'>修改用户组</a></li>") };

return RedirectToAction("ManageError", "Prompt", _e);

}

}
