如何从动作返回默认视图？

Question

我有两个视图，它们包含相同的登录表单。表单调用相同的操作。我想在页面中显示错误。我重定向到indexpage。但是当我从登录页面登录错误在indexpage中显示但是我希望从登录页面登录时在登录页面中显示错误，并且在从索引页面登录时在索引页面中显示错误

我的代码是

public ActionResult ValidateLogIn(UserLogin users)
    {
        if (ModelState.IsValid)
        {
            var result = _accountUserService.GetAccountUserByEmailId(users.Email);
            if (result != null)
            {
                if (result.Password == users.Password && result.Active)
                {
                    Session.Add("Username", result.Email);
                    ViewBag.email = users.Email;
                    return View("Index");
                    //return full form registration;    
                }
                ViewBag.UError = NcMessage.NotAcitvated;
            }
            else
            {
                ViewBag.UError = NcMessage.UsernameNotFound;
            }
        }
        return View("Index");
    }

我该怎么办？

您只需更改最后一行即可返回login视图

public ActionResult ValidateLogIn(UserLogin users)
    {
        if (ModelState.IsValid)
        {
            var result = _accountUserService.GetAccountUserByEmailId(users.Email);
            if (result != null)
            {
                if (result.Password == users.Password && result.Active)
                {
                    Session.Add("Username", result.Email);
                    ViewBag.email = users.Email;
                    return View("Index");
                    //return full form registration;    
                }
                ViewBag.UError = NcMessage.NotAcitvated;
            }
            else
            {
                ViewBag.UError = NcMessage.UsernameNotFound;
            }
        }
        return View("Login");
      // Return to Login page as  Authentication is unsuccessful or ModelState is Invalid
    }
