MarshalByRefObject 的DOME代码

        今天研究了下MarshalByRefObject跨程序通讯，由于今天很晚了，先贴出DOME代码。

 

　　　分别建立2个winform程序，WinClient和WinServer，2个项目中都有CommunicationInfo类（你也可以将CommunicationInfo做成一个类库供2个winform程序引用）。

 

　　贴上代码：

　　CommunicationInfo.cs　　

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;public class CommunicationInfo : MarshalByRefObject{public CommunicationInfo(){}public override object InitializeLifetimeService(){//return base.InitializeLifetimeService();
            System.Runtime.Remoting.Lifetime.ILease aLease= (System.Runtime.Remoting.Lifetime.ILease)base.InitializeLifetimeService();if (aLease.CurrentState == System.Runtime.Remoting.Lifetime.LeaseState.Initial){// 不过期aLease.InitialLeaseTime = TimeSpan.Zero;}return aLease;}public class CommunicationEventArg : EventArgs{public string Name = string.Empty;}public delegate void JobAddEventHandler(CommunicationEventArg e);public event JobAddEventHandler OnJobAdd;public void CallJobAddEvent(string name){CommunicationEventArg ee = new CommunicationEventArg();ee.Name = name;OnJobAdd(ee);}}

WinServer

//测试事件private void _communicationInfo_OnJobAdd(RemoteObject.CommunicationInfo.CommunicationEventArg e){textBox1.Text = textBox1.Text + "\r\n" + e.Name;}RemoteObject.CommunicationInfo _communicationInfo = null;private void button1_Click(object sender, EventArgs e){if (_communicationInfo == null){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 RemoteObject.CommunicationInfo();_communicationInfo.OnJobAdd += new RemoteObject.CommunicationInfo.JobAddEventHandler(_communicationInfo_OnJobAdd);System.Runtime.Remoting.RemotingServices.Marshal(_communicationInfo, "message1",typeof(RemoteObject.CommunicationInfo));}}

WinClient

RemoteObject.CommunicationInfo _communicationInfo;private void button1_Click(object sender, EventArgs e){if (_communicationInfo == null){System.Runtime.Remoting.Channels.Tcp.TcpClientChannel _clientChannel;_clientChannel = new System.Runtime.Remoting.Channels.Tcp.TcpClientChannel();System.Runtime.Remoting.Channels.ChannelServices.RegisterChannel(_clientChannel, true);_communicationInfo = (RemoteObject.CommunicationInfo)System.Activator.GetObject(typeof(RemoteObject.CommunicationInfo), "tcp://127.0.0.1:18089/message1", System.Runtime.Remoting.WellKnownObjectMode.Singleton);}_communicationInfo.CallJobAddEvent(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss fff"));//启动事件 
           }
