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

定义

命名空间:
System.Runtime.Remoting.Proxies
程序集:
mscorlib.dll

为指定的 ObjRef远程对象创建远程处理代理的实例，并位于服务器上。

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);
abstract member CreateProxy : System.Runtime.Remoting.ObjRef * Type * obj * System.Runtime.Remoting.Contexts.Context -> System.Runtime.Remoting.Proxies.RealProxy

[<System.Security.SecurityCritical>]
abstract member CreateProxy : System.Runtime.Remoting.ObjRef * Type * obj * System.Runtime.Remoting.Contexts.Context -> System.Runtime.Remoting.Proxies.RealProxy

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

参数

objRef
ObjRef

要为其创建代理的远程对象的对象引用。

serverType
Type

远程对象所在的服务器的类型。

serverObject
Object

服务器对象。

serverContext
Context

服务器对象所在的上下文。

返回

RealProxy

指定对象中介绍 ObjRef的远程对象远程处理代理的新实例。

属性
SecurityCriticalAttribute

示例

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

注解

注释

在从 ObjRef 引用使用 ProxyAttribute 特性标记的类的实例中创建代理时，将调用当前方法。 因此，仅当 ObjRef 从调用的返回或参数接收方法，或在客户端激活对象期间使用此方法。 不 ProxyAttribute 用于已知对象类型。
