C# MVC-后期视图模型未填充

行动方法：

[HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Register(RegisterViewModel blahblah)
    {
        HttpPostedFileBase uploadFile;
        if (ModelState.IsValid)
        {
            if (blahblah != null)
            {
                var obj = new tblPersonalDetail()
                {
                    FirstName = blahblah.FirstName,
                    LastName = blahblah.LastName,
                    Title = blahblah.Title,
                    Address = blahblah.Address,
                    Suburb = blahblah.Suburb,
                    HomePhone = blahblah.HomePhone,
                    Mobile = blahblah.Mobile,
                    Email = blahblah.Email,
                    EmergencyName = blahblah.EmergencyContactName,
                    EmergencyPhone = blahblah.EmergencyContactPhone,
                    EmergencyEmail = blahblah.EmergencyContactEmail,
                    EmergencyRelation = blahblah.EmergencyContactRelation,
                    DrivingLicenceExpiryDate = blahblah.DrivingLicenceExpiryDate,
                    DrivingLicenceNo = blahblah.DrivingLicenceNo,
                    DateofBirth = blahblah.DateofBirth
                };


                //if (uploadFile != null && !string.IsNullOrEmpty(uploadFile.FileName))
                //{
                //    uploadFile.SaveAs(Server.MapPath($@"~\Content\Images\{uploadFile.FileName}"));
                //    obj.ScannedImageLocation = ($@"~\Content\Images\{uploadFile.FileName}");
                //}
                db.tblPersonalDetails.Add(obj);
                db.SaveChanges();
                return RedirectToAction("Index");
            }
        }

        return View(blahblah);
    }

--registerviewmodel

 public class RegisterViewModel
 {
    public string Title;
    public string FirstName;
    public string LastName;
    public string Address;
    public string Suburb;
    public string HomePhone;
    public string Mobile;
    public string Email;
    public string EmergencyContactName;
    public string EmergencyContactRelation;
    public string EmergencyContactPhone;
    public string EmergencyContactEmail;
    public string DrivingLicenceNo;
  //  [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MM-dd}")]
    public DateTime DrivingLicenceExpiryDate;
    public string DrivingLicenceImage;
  //  [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString ="{0:yyyy-MM-dd}")]
    public DateTime DateofBirth;
    public string Notes;
    public string NextAppointment;
    public string Name
    {
        get
        {
            return $"{FirstName} {LastName}";
        }
    }


}

post上的viewmodel全部为空。如果我使用entityframework生成的tblPersonalDetail模型类，然后更改视图中的引用（Register.cshtml），它会发布数据。但是，不能使用自定义视图模型。 --Register.cshtml

@model Leo.ViewModel.RegisterViewModel
@{
 ViewBag.Title = "Register New User";
