扩展另一个类以制作自定义类类型 HttpContext.User

Question

我正在使用 c#、asp.net-mvc5 和实体框架 6 在 Visual Studio 2013 中制作模拟社交媒体应用程序。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" });
    }

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

“非静态字段、方法或属性‘System.Web.HttpContext.User.get’需要对象引用”

我是否需要让我的 AppUser 类扩展一个 HttpContext 类以消除此错误，还是必须按原样重写整个类？

 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

HttpContext.User.Identity.IsAuthenticated

进入

HttpContext.Current.User.Identity.IsAuthenticated

帮我解决了这个问题
