ProxyAttribute.CreateProxy(ObjRef, Type, Object, Context) 方法

定義

命名空間:
System.Runtime.Remoting.Proxies
組件:
mscorlib.dll

為指定的 ObjRef遠端物件建立一個遠端代理實例，該物件位於伺服器上。

public:
 virtual System::Runtime::Remoting::Proxies::RealProxy ^ CreateProxy(System::Runtime::Remoting::ObjRef ^ objRef, Type ^ serverType, System::Object ^ serverObject, System::Runtime::Remoting::Contexts::Context ^ serverContext);
public virtual System.Runtime.Remoting.Proxies.RealProxy CreateProxy(System.Runtime.Remoting.ObjRef objRef, Type serverType, object serverObject, System.Runtime.Remoting.Contexts.Context serverContext);
[System.Security.SecurityCritical]
public virtual System.Runtime.Remoting.Proxies.RealProxy CreateProxy(System.Runtime.Remoting.ObjRef objRef, Type serverType, object serverObject, System.Runtime.Remoting.Contexts.Context serverContext);

Public Overridable Function CreateProxy (objRef As ObjRef, serverType As Type, serverObject As Object, serverContext As Context) As RealProxy

範例

virtual RealProxy^ CreateProxy( ObjRef^ objRef1, Type^ serverType, Object^ serverObject, Context^ serverContext ) override
{
   MyProxy^ myCustomProxy = gcnew MyProxy( serverType );
   if ( serverContext != nullptr )
   {
      RealProxy::SetStubData( myCustomProxy, serverContext );
   }

   if ( ( !serverType->IsMarshalByRef) && (serverContext == nullptr) )
   {
      throw gcnew RemotingException( "Bad Type for CreateProxy" );
   }

   return myCustomProxy;
}

public override RealProxy CreateProxy(ObjRef objRef1,
   Type serverType,
   object serverObject,
   Context serverContext)
{
   MyProxy myCustomProxy = new MyProxy(serverType);
   if(serverContext != null)
   {
      RealProxy.SetStubData(myCustomProxy,serverContext);
   }
   if((!serverType.IsMarshalByRef)&&(serverContext == null))
   {
      throw new RemotingException("Bad Type for CreateProxy");
   }
   return myCustomProxy;
}

Public Overrides Function CreateProxy(objRef1 As ObjRef, serverType As Type, _
            serverObject As Object, serverContext As Context) As RealProxy
   Dim myCustomProxy As New MyProxy(serverType)
   If Not (serverContext Is Nothing) Then
      RealProxy.SetStubData(myCustomProxy, serverContext)
   End If
   If Not serverType.IsMarshalByRef And serverContext Is Nothing Then
      Throw New RemotingException("Bad Type for CreateProxy")
   End If
   Return myCustomProxy
End Function 'CreateProxy

備註

Note

當前方法是在從 ObjRef 一個引用帶有屬性的 ProxyAttribute 類別的實例中建立代理時被呼叫。 因此，此方法僅在呼叫時從回傳或參數中接收到， ObjRef 或在用戶端啟用物件啟動時使用。 該 ProxyAttribute 不用於知名的物件類型。
