call MVC Validator in a get method

Question

In my Controllor, in the get methode, I create My viewModel with elment from querystrings. I need to validate email in MyViewModel, how can call my validator [EmailValidator]??

 public ActionResult Index(string countryCode)
    {
        var loginViewModel = _loginViewModelFactory.GetLoginViewModel();
        if (**ifvalid(loginViewModel.Mail**))
        {
            _loginViewModelFactory.mail=string.empty;
        }
        return View(loginViewModel);
    }

this is my model:

  public class LoginViewModel
    {
        [MailValidator]
        public string Mail { get; set; }
        public string Password { get; set; }
}

I have a validator but I need to call it in the get method: when the email field is not valid i change the value of the field to string.empty — user1428798, May 23 '14 at 11:21

Try this

public ActionResult Index(string countryCode)
{
    var loginViewModel = _loginViewModelFactory.GetLoginViewModel();
    ModelState.Clear();
    TryValidateModel(loginViewModel)
    if (ModelState["Mail"].Errors.Any())
    {
        _loginViewModelFactory.mail=string.empty;
    }
    return View(loginViewModel);
}
