ASP.NET MVC5网站开发之用户资料的修改和删除3（七）

这次主要实现管理后台界面用户资料的修改和删除，修改用户资料和角色是经常用到的功能，但删除用户的情况比较少，为了功能的完整性还是坐上了。主要用到两个action “Modify”和“Delete”。

一、用户资料修改（Modify）

此功能分两个部分：

public ActionResult Modify(int id) 用于显示用户信息

[httppost]

public ActionResult Modify(FormCollection form)用户就收前台传来的信息并修改

1、显示用户信息

/// <summary>  /// 修改用户信息  /// </summary>  /// <param name="id">用户主键</param>  /// <returns>分部视图</returns>  public ActionResult Modify(int id)  {   //角色列表   var _roles = new RoleManager().FindList();   List<SelectListItem> _listItems = new List<SelectListItem>(_roles.Count());   foreach (var _role in _roles)   {    _listItems.Add(new SelectListItem() { Text = _role.Name, Value = _role.RoleID.ToString() });   }   ViewBag.Roles = _listItems;   //角色列表结束   return PartialView(userManager.Find(id));  }

此action有一个参数id,接收传入的用户ID,在action中查询角色信息，并利用viewBage传递到视图，并通过return PartialView(userManager.Find(id))向视图传递用户模型返回分部视图。

视图代码如下：

@model Ninesky.Core.User@using (Html.BeginForm()){ @Html.AntiForgeryToken() <div class="form-horizontal">  @Html.ValidationSummary(true, "", new { @class = "text-danger" })  @Html.HiddenFor(model => model.UserID)  <div class="form-group">   @Html.LabelFor(model => model.RoleID, htmlAttributes: new { @class = "control-label col-md-2" })   <div class="col-md-10">    @Html.DropDownListFor(model => model.RoleID, (IEnumerable<SelectListItem>)ViewBag.Roles, new { @class = "form-control" })    @Html.ValidationMessageFor(model => model.RoleID, "", new { @class = "text-danger" })   </div>  </div>  <div class="form-group">   @Html.LabelFor(model => model.Username, htmlAttributes: new { @class = "control-label col-md-2" })   <div class="col-md-10">    @Html.EditorFor(model => model.Username, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })    @Html.ValidationMessageFor(model => model.Username, "", new { @class = "text-danger" })   </div>  </div>  <div class="form-group">   @Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "control-label col-md-2" })   <div class="col-md-10">    @Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "form-control" } })    @Html.ValidationMessageFor(model => model.Name, "", new { @class = "text-danger" })   </div>  </div>  <div class="form-group">   @Html.LabelFor(model => model.Sex, htmlAttributes: new { @class = "control-label col-md-2" })   <div class="col-md-10">    @Html.RadioButtonFor(model => model.Sex, 1) 男    @Html.RadioButtonFor(model => model.Sex, 0) 女    @Html.RadioButtonFor(model => model.Sex, 2) 保密    @Html.ValidationMessageFor(model => model.Sex, "", new { @class = "text-danger" })   </div>  </div>  <div class="form-group">   @Html.LabelFor(model => model.Password, htmlAttributes: new { @class = "control-label col-md-2" })   <div class="col-md-10">    @Html.EditorFor(model => model.Password, new { htmlAttributes = new { @class = "form-control" } })    @Html.ValidationMessageFor(model => model.Password, "", new { @class = "text-danger" })   </div>  </div>  <div class="form-group">   @Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" })   <div class="col-md-10">    @Html.EditorFor(model => model.Email, new { htmlAttributes = new { @class = "form-control" } })    @Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" })   </div>  </div>  <div class="form-group">   @Html.LabelFor(model => model.LastLoginTime, htmlAttributes: new { @class = "control-label col-md-2" })   <div class="col-md-10">    @Html.EditorFor(model => model.LastLoginTime, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })    @Html.ValidationMessageFor(model => model.LastLoginTime, "", new { @class = "text-danger" })   </div>  </div>  <div class="form-group">   @Html.LabelFor(model => model.LastLoginIP, htmlAttributes: new { @class = "control-label col-md-2" })   <div class="col-md-10">    @Html.EditorFor(model => model.LastLoginIP, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })    @Html.ValidationMessageFor(model => model.LastLoginIP, "", new { @class = "text-danger" })   </div>  </div>  <div class="form-group">   @Html.LabelFor(model => model.RegTime, htmlAttributes: new { @class = "control-label col-md-2" })   <div class="col-md-10">    @Html.EditorFor(model => model.RegTime, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })    @Html.ValidationMessageFor(model => model.RegTime, "", new { @class = "text-danger" })   </div>  </div> </div>}
