Contoh

Contoh kode berikut menunjukkan cara mendapatkan kontrol kustom dari Control kelas, lalu membuat adaptor terkait yang diwarisi dari ControlAdapter kelas. Adaptor mengambil alih Control properti dan mengembalikan referensi yang sangat diketik ke kontrol.

#using <System.Web.Mobile.dll>
#using <System.dll>
#using <System.Web.dll>

using namespace System;
using namespace System::Web::UI;
using namespace System::Web::UI::Adapters;
using namespace System::Web::UI::WebControls;

public ref class CustomControl: public Control{};

public ref class CustomControlAdapter: public ControlAdapter
{
public:

   property System::Web::UI::Control^ Control 
   {
      // Return a strongly-typed reference to your custom control.
      System::Web::UI::Control^ get()
      {
         return (CustomControl^)ControlAdapter::Control;
      }
   }
   // Override other ControlAdapter members, as necessary. 
};

using System;
using System.Web.UI;
using System.Web.UI.Adapters;
using System.Web.UI.WebControls;

public class CustomControl : Control
{
    // Add your custom control code.
}

public class CustomControlAdapter : ControlAdapter
{
    // Return a strongly-typed reference to your custom control.
    public new CustomControl Control
    {
        get
        {
            return (CustomControl)base.Control;
        }

        // Override other ControlAdapter members, as necessary. 
    }
}

Imports System.Web.UI
Imports System.Web.UI.Adapters
Imports System.Web.UI.WebControls

Public Class CustomControl
    Inherits Control

    ' Add your custom control code.

End Class

Public Class CustomControlAdapter
    Inherits ControlAdapter

    ' Return a strongly-typed reference to your custom control.
    Public Shadows ReadOnly Property Control() As CustomControl
        Get
            Return CType(MyBase.Control, CustomControl)
        End Get
    End Property

    ' Override other ControlAdapter member as necessary. 

End Class

Keterangan

Ketika adaptor kontrol turunan dilampirkan ke kontrol, .NET Framework memanggil anggota adaptor tertentu alih-alih anggota kontrol.

Catatan Bagi Inheritor

Ketika Anda mewarisi dari ControlAdapter kelas, minimal, Anda harus menerapkan Control properti untuk mengembalikan instans kontrol yang sangat diketik, seperti yang ditunjukkan di bagian Contoh.
