Question

我想使用MVC从SQL中的aspnetusers数据库锁定用户。这是我的管理员控制器：

 @using (Html.BeginForm("LockUser", "Admin", new { id = x.Id }))
 {
    <input type="submit" class="button" value="Lock" />
 }

这是我的管理员观点：

System.InvalidOperationException was unhandled by user code
  HResult=-2146233079
  Message=The entity type ApplicationUser is not part of the model for the current context.
  Source=EntityFramework

当我点击按钮时，我的数据库中没有任何反应，我仍然可以使用该帐户登录。我收到这个错误：

使用UserManager进行更新时，请使用以下代码。您需要在数据库上下文中调用SaveChanges方法以保持更改，否则它将不会在数据库中持久存在。

var datastore = new UserStore<ApplicationUser>();
var manager = new UserManager<ApplicationUser,string>( dataStore);
//update current user object in memory
//var user = User.Identity.GetApplicationUser();
var user = manager.FindById(Id)
user.LockoutEnabled = true;
user.LockoutEndDateUtc = DateTime.UtcNow.AddYears(2);
manager.UpdateAsync(user);
var dbcontext = datastore.Context;
//update user object in database
dbcontext.SaveChanges();

在代码顶部包含以下命名空间。此外，在这种情况下，您只需将光标放在红色下划线的左下角，然后单击图标即可显示Visual Studio的建议。

using Microsoft.AspNet.Identity;
using  Microsoft.AspNet.Identity.EntityFramework;

添加对以下程序集的引用：Microsoft.AspNet.Identity.Core.dll and Microsoft.AspNet.Identity.EntityFramework.dll
