Question

метод

действия:

[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,

        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 DateTime DateofBirth; 
    public string Notes; 
    public string NextAppointment; 
    public string Name 
    { 
     get 
     { 
      return $"{FirstName} {LastName}"; 
     } 
    } 


} 

модели представления на пост все нуль. если я использую класс модели tblPersonalDetail, сгенерированный с помощью entityframework, а затем изменим ссылку в представлении (Register.cshtml), он публикует данные. Однако не с пользовательской моделью просмотра. --Register.cshtml

Answer 1

Вы fields не properties, вам необходимо изменить определение вида модели, чтобы иметь такие свойства, как:

public class RegisterViewModel 
{ 
    public string Title { get; set;} 
    public string FirstName { get; set;} 
    //............ 
    //............ 
} 

Answer 2

модели по умолчанию вяжущего в ASP .NET MVC привязывается только к общедоступным свойствам, однако в настоящее время вы используете поля, которые не будут связаны.

Вам просто нужно, чтобы украсить их необходимыми геттеры/сеттеры, как видно ниже, чтобы превратить их в свойства:

public class RegisterViewModel 
{ 
    public string Title { get; set; } 
    public string FirstName { get; set; } 
    public string LastName { get; set; } 

    // Others omitted for brevity 
}
