ASP.Net MVC中的字段验证

Question

我有一个登录页面和一个注册页面。两者都顺利验证。当我将成员资格添加到登录控制器时，登录页面停止验证字段，但是根据我的代码，它只是弹出登录失败的消息。以下是我的行动和观点。知道为什么它没有验证知道我在注册视图中有相同的代码及其验证。

动作

[HttpPost]
        public ActionResult SignIn(tbl_User user)
        {
            try
            {
                if (Membership.ValidateUser(user.UserEmail, user.Password))
                {
                    FormsAuthentication.SetAuthCookie(user.UserEmail, false);
                    return RedirectToAction("Index", "Home", new { area = "Common" });
                }
                else
                {
                    TempData["Msg"] = "Login Failed";
                    return RedirectToAction("Index");

                }
            }
            catch(Exception e)
            {
                TempData["Msg"] = "Login Failed "+e.Message;
                return RedirectToAction("Index");
            }
        }
