範例

以下程式碼範例展示了如何使用來 ActivatedClientTypeEntry 註冊客戶端啟用的遠端物件。範例包含三個部分：客戶端、伺服器，以及由客戶端與伺服器使用的遠端物件。

以下程式碼範例展示了一個客戶端：

以下程式碼範例展示了此用戶端的伺服器：

   Console::WriteLine( "Press enter to stop this process" );
   Console::ReadLine();
}

using System.Runtime.Remoting.Channels.Tcp;

public class MyServer

        Console.WriteLine("Press enter to stop this process")
        Console.ReadLine()

End Class

以下程式碼範例提供用戶端與伺服器所使用的遠端物件：

using namespace System;
public ref class HelloServer: public MarshalByRefObject
{
public:
   HelloServer( String^ myString )
   {
      Console::WriteLine( "HelloServer activated" );
      Console::WriteLine( "Paramater passed to the constructor is {0}", myString );
   }

   String^ HelloMethod( String^ myName )
   {
      Console::WriteLine( "HelloMethod : {0}", myName );
      return String::Format( "Hi there {0}", myName );
   }

};

using System;
public class HelloServer : MarshalByRefObject
{
    public HelloServer(String myString)
    {
        Console.WriteLine("HelloServer activated");
        Console.WriteLine("Parameter passed to the constructor is "+myString);
    }
    public String HelloMethod(String myName)
    {
        Console.WriteLine("HelloMethod : {0}",myName);
        return "Hi there " + myName;
    }
}

Public Class HelloServer
    Inherits MarshalByRefObject
    
    Public Sub New(myString As String)
        Console.WriteLine("HelloServer activated")
        Console.WriteLine("Parameter passed to the constructor is " + myString)
    End Sub
    
    Public Function HelloMethod(myName As String) As String
        Console.WriteLine("HelloMethod : {0}", myName)
        Return "Hi there " + myName
    End Function 'HelloMethod
End Class

備註

要在用戶端建立由用戶端啟用的物件實例，你必須知道它 Type ，並且必須透過此 RegisterActivatedClientType 方法在用戶端註冊。要取得代理伺服器以啟用客戶端啟用物件的新實例，客戶端必須先註冊一個通道， ChannelServices 然後透過呼叫 new來啟動該物件。

要啟用帶有 new 關鍵字的客戶端啟用物件類型，必須先在用戶端使用該 RegisterActivatedClientType 方法註冊該物件類型。透過呼叫 RegisterActivatedClientType ，你會讓遠端應用程式的基礎設施知道遠端應用程式的位置，而遠端應用程式正 new 試圖建立它。反之，若你使用此 Activator.CreateInstance 方法建立客戶端啟用物件的新實例，必須提供遠端應用程式的 URL 作為參數，因此客戶端無需事先註冊。若要提供 Activator.CreateInstance 該方法並提供你想建立物件的伺服器 URL，你必須將該 URL 封裝在類別的 UrlAttribute 實例中。
