这是我的模特课：

This is my model class:

public class RegisterModel
{
    [Required]
    [Display(Name = "User name")]
    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]
    [Display(Name = "EMail")]
    public string Email { get; set; }

}

//用户个人资料

//User profile

[Table("UserProfile")]
public class UserProfile
{
   [Key]
   [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
   public int UserId { get; set; }
   public string UserName { get; set; }
   public string Email { get; set; }
}

public ActionResult Register(RegisterModel model)
       {
           if (ModelState.IsValid)
           {
               // Attempt to register the user 1st step
               try
               {

                   WebSecurity.CreateUserAndAccount(model.UserName, model.Password,new { Email = model.Email }, true);
           WebSecurity.Login(model.UserName, model.Password);
           return RedirectToAction("Index", "Home");
  }
                catch (MembershipCreateUserException e)
                {
                    ModelState.AddModelError("", ErrorCodeToString(e.StatusCode));
                }
            }

            // If we got this far, something failed, redisplay form
            return View(model);
        }


// My controller class;
// -------------------------------------------------------------------
 public ActionResult ForgotPassword(string un, string rt)
        {
            UsersContext db = new UsersContext();
            //TODO: Check the un and rt matching and then perform following
            //get userid of received username
            var userid = (from i in db.UserProfiles
                          where i.UserName == un
                          select i.UserId).FirstOrDefault();
            //check userid and token matches
            bool any = (from j in db.webpages_Memberships
                        where (j.UserId == userid)
                        && (j.PasswordVerificationToken == rt)
                        //&& (j.PasswordVerificationTokenExpirationDate < DateTime.Now)
                        select j).Any();

            if (any == true)

                    }

                    //display message
                    TempData["Message"] = "Success! Check email we sent. Your New Password Is " + newpassword;
                }
                else
                {
                    TempData["Message"] = "Hey, avoid random request on this page.";
                }
            }
            else
            {
                TempData["Message"] = "Username and token not maching.";
            }           
            return View();
        }

        //3rd step
        [HttpPost]
        [AllowAnonymous]

        public ActionResult ForgotPassword(string UserName)

            }
            else

                var token = WebSecurity.GeneratePasswordResetToken(UserName);
                //create url with above token
                var resetLink = "<a href="" + Url.Action("ResetPassword", "Account", new { un = UserName, rt = token }, "http") + "">Reset Password</a>";
                //get user emailid
                UsersContext db = new UsersContext();
                var emailid = (from i in db.UserProfiles
                               where i.UserName == UserName
                               select i.Email).FirstOrDefault();
                //send mail
                string subject = "Password Reset Token";
                string body = "Please find the Password Reset Token<br />" + resetLink; //edit it
                try
                {
                    SendEMail(emailid, subject, body);
                    TempData["Message"] = "Mail Sent.";
                }
                catch (Exception ex)
                {
                    TempData["Message"] = "Error occured while sending email." + ex.Message;
                }
                //only for testing
                TempData["Message"] = resetLink;
            }

            return View();
        }
