ViewModel クラスを使用してデータ入力ページをバインドしています。ビュー モデル クラスの階層は次のようになります。

public ClassA
{
    public SomeModelType1 MyProperty1 { get; set; }
    public List<SomeModelType2> MyProperty2 { get; set; }
}

public class SomeModelType1 
{
    public string Name { get; set; }
    public SomeModelType3 MyProperty13 { get; set; }
}
public class SomeModelType3
{
    public int Id { get; set; }
}

クラス A をビューにバインドすると、次のようにテキスト ボックスがバインドされます。

Model.MyProperty1.Name)%> および Model.MyProperty1.SomeModelType3 .Id, new { @id = "hdfId" })%>

しかし、私が書いたフォームを送信すると、 [AcceptVerbs(HttpVerbs.Post)] public ActionResult BuildProfile(ClassA a) { //some logic }

そのため、a.MyProperty1値をデバッグすると、常に MyProperty1 が null 値として取得されます。誰か助けてください。どこが間違っているのかわかりません。

メソッドを取得

 [AcceptVerbs(HttpVerbs.Get)]
public ActionResult BuildProfile(Int32 UserId, Int32 CompanyDentistId, Int32 AccountId)
{
A objProfile = new A ();          
objProfile.CurrentStep = 1;
objProfile.MyProperty1.MyProperty13.CompanyId = CompanyId;
objProfile.MyProperty1.MyProperty13.AccountId = AccountId;
objProfile.MyProperty1.UserId = UserId;
return View(objProfile);
}

投稿方法

[AcceptVerbs(HttpVerbs.Post)]
    public ActionResult BuildProfile(BuildProfileViewModel a)
    {          
        return RedirectToAction("BuildProfile", new { UserId = a.MyProperty1.UserId, CompanyId = a.MyProperty1.MyProperty13.CompanyId, AccountId = a.MyProperty1.MyProperty13.AccountId });

}

バインドし直すすべてのビューでは、ビューで使用されるすべてのクラスにパラメーターなしのコンストラクターが必要です。また、そのコンストラクターのビューで使用しているすべてのクラスをインスタンス化する必要があります。

public ClassA
{
    public ClassA(){
        MyProperty1 = new SomeModelType1();
        MyProperty2 = new List<SomeModelType2>();
    }

    public SomeModelType1 MyProperty1 { get; set; }
    public List<SomeModelType2> MyProperty2 { get; set; }
}

public class SomeModelType1 
{
    public SomeModelType1(){
        MyProperty13 = new SomeModelType3();
    } 

    public string Name { get; set; }
    public SomeModelType3 MyProperty13 { get; set; }
}
public class SomeModelType3
{
    public int Id { get; set; }
}
