在模型狀態驗證之前更改模型ASP.NET MVC

[英]Change model before model state validation ASP.NET MVC

我正在使用萬無一失的庫來進行動態屬性驗證。

該模型如下:

public class ProfileQuestion
{
        public int QuestionId { get; set; }
        public string QuestionText { get; set; }
        public int QuestionTypeId { get; set; }
        [RequiredIf("Isrequired", true, ErrorMessage = "Required")]
        public string Answer { get; set; }
        public string Day { get; set; }
        public string Month { get; set; }
        public string Year { get; set; }   
        public string Areacode { get; set; }
        public string Zipcode { get; set; }
        public List<ProfileOptions> OptionsList { get; set; }
        public bool Isrequired = false;
}

我們有一個問題列表,其中一些問題是必需的。 如果需要提問,則Isrequired = true 我在模型狀態驗證之前設置isrequired標志,但是ModelState.IsValid始終為false。

var mandatoryQuestions = objBusLayer.GetMandatoryQuestionIds(m);

foreach (ProfileQuestion question in Response)
{
    if (question.QuestionId == 2)
    {
        string date = question.Year + @"/" + question.Month + @"/" + 
question.Day;
        DateTime outdate;

        if (DateTime.TryParse(date, out outdate))
        {
            question.Answer = date;
        }
    }

    if (question.QuestionId == 3)
    {
        question.Answer = question.Areacode + '-' + question.Zipcode;
    }

    if (mandatoryQuestions.Contains(question.QuestionId.ToString()))
    {
        question.Isrequired = true;
    }
}

if (ModelState.IsValid)
{
    Encryption encObj = new Encryption();
    string decryptedExtPanelistId = encObj.DecryptText(e, password);
    objBusLayer.Register(decryptedExtPanelistId, m, Response);
    return RedirectToAction("Register", new { e = e, m = m, pg = pg + 1 });
}

ViewBag.pageId = pg;
ViewBag.extpnltid = e;
ViewBag.mid = m;

return View(Response);

我找不到問題,有人可以幫助我解決此問題嗎?

嘗試結合使用ModelState.Clear()和TryValidateModel()。

ModelState.Clear();
TryValidateModel(Response);

問候。
