扩展另一个 class 以创建自定义 class 类型 HttpContext.User

Question

我正在 Visual Studio 2013 年制作一个模拟社交媒体应用程序，使用 c#、asp.net-mvc5 和 entity framework 6. 我正在尝试添加自定义用户身份验证我已经在 web.config:

中实现了身份验证

<authentication mode="Forms">
  <forms loginUrl="~/AppUsers/Login" timeout="3000" />
</authentication>

并确保 ActionResult 在登录时创建一个 cookie

    [HttpPost]
    public ActionResult Login(string userName, string password)
    {
        AppUser user = null;


        if (db.AppUser.Any(m => m.UserName == userName)) {
            user = db.AppUser.Where(m => m.UserName == userName).First();
            if (user.Password == password) {
                FormsAuthentication.SetAuthCookie(userName, true);
                return RedirectToAction("AppUserProfile", new { id = user.Id });
            }
        }
        return RedirectToAction("Login", new { message = "Invalid Password" });
    }

但我现在卡住了，每当我尝试检查是否 HttpContext.User.Identity.IsAuthenticated 时，我都会收到一条错误消息：

"An object reference is required for the non-static field, method, or property 'System.Web.HttpContext.User.get'"

我需要让我的 AppUser class 扩展一个 HttpContext class 来消除这个错误，还是我必须按原样重写整个 class？

 public class AppUser
{

    [Key]
    public int Id { get; set; }

    [Required]
    public string FirstName { get; set; }
    [Required]
    public string LastName { get; set; }

    [Required]
    public string UserName { get; set; }

    [Required]
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Confirm Password")]
    [Compare("Password", ErrorMessage = "The password and confirmation password do not match")]
    public string ConfirmPassword { get; set; }

    [Required]
    [EmailAddress]
    [Display(Name = "Email")]
    public string EmailAddress { get; set; }

    public virtual ICollection<UserPost> UserPosts { get; set; }
}

制作中

HttpContext.User.Identity.IsAuthenticated

进入

HttpContext.Current.User.Identity.IsAuthenticated

为我解决了问题
