這次主要實現管理后臺界面用戶資料的修改和刪除，修改用戶資料和角色是經常用到的功能，但刪除用戶的情況比較少，為了功能的完整性還是坐上了。主要用到兩個action “Modify”和“Delete”。

一、用戶資料修改（Modify）

此功能分兩個部分：

public ActionResult Modify(int id) 用于顯示用戶信息

[httppost]

public ActionResult Modify(FormCollection form)用戶就收前臺傳來的信息并修改

1、顯示用戶信息

/// <summary>  /// 修改用戶信息  /// </summary>  /// <param name="id">用戶主鍵</param>  /// <returns>分部視圖</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;   //角色列表結束   return PartialView(userManager.Find(id));  }

此action有一個參數id,接收傳入的用戶ID,在action中查詢角色信息，并利用viewBage傳遞到視圖，并通過return PartialView(userManager.Find(id))向視圖傳遞用戶模型返回分部視圖。

視圖代碼如下：
