C# 使用MarshalByRefObject跨程序调用方法

MarshalByRef  是通过使用代理交换消息来跨应用程序域边界进行通信的对象的基类。不是从 MarshalByRef  继承的对象根据值隐式封送。当远程应用程序引用根据值封送的对象时，将跨应用程序域边界传递该对象的副本。

程序1（服务器端）启动时运行
参照中追加System.Runtime.Remoting

Remote .CommunicationInfo _communicationInfo;

System.Runtime.Remoting.Channels.Tcp.TcpServerChannel servChannel = new System.Runtime.Remoting.Channels.Tcp.TcpServerChannel(18089);

System.Runtime.Remoting.Channels.ChannelServices.RegisterChannel(servChannel, true);

_communicationInfo = new Remote .CommunicationInfo();

_communicationInfo.OnJobAdd += new　Remote .CommunicationInfo.JobAddEventHandler(_communicationInfo_OnJobAdd);

System.Runtime.Remoting.RemotingServices.Marshal(_communicationInfo, "message1",typeof(Remote .CommunicationInfo));

//测试事件

privatevoid _communicationInfo_OnJobAdd(Remote .CommunicationInfo.CommunicationEventArg e)

{

MessageBox.Show("TEST OK");

}
================================================
程序2（客户端）调用方法时运行
参照中追加System.Runtime.Remoting

System.Runtime.Remoting.Channels.Tcp.TcpClientChannel _clientChannel;

_clientChannel = new System.Runtime.Remoting.Channels.Tcp.TcpClientChannel();

System.Runtime.Remoting.Channels.ChannelServices.RegisterChannel(_clientChannel, true);

Remote .CommunicationInfo _communicationInfo;

_communicationInfo = (Remote .CommunicationInfo)

System.Activator.Get (typeof(Remote .CommunicationInfo),"tcp://localhost:18089/message1", System.Runtime.Remoting.WellKnown Mode.Singleton);

_communicationInfo.CallJobAddEvent();//启动事件
