C# NetRemoting实现双向通信

闲来无事想玩玩双向通信，实现类似QQ的互发消息的功能。于是乎开始学习.Net Remoting.

.Net Remoting 是由客户端通过Remoting，访问通道以获得服务端对象，再通过代理解析为客户端对象来实现通信的。也就是说对象是由服务端创建的。

先上代码

首先是ICommand库

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ICommand
{
  public interface IRemotingObject
  {
    event SendHandler ClientToServer;
    event ReceiveHandler ServerToClient;
    event UserChangedHandler Login;
    event UserChangedHandler Exit;
    /// <summary>
    /// 加法运算
    /// </summary>
    /// <param name="x1">参数1</param>
    /// <param name="x2">参数2</param>
    /// <returns></returns>
    string SUM(int x1, int x2);
    /// <summary>
    /// 获取服务端事件列表
    /// </summary>
    Delegate[] GetServerEventList();
    /// <summary>
    /// 发送消息
    /// </summary>
    /// <param name="info"></param>
    /// <param name="toName"></param>
    void ToServer(object info, string toName);
    /// <summary>
    /// 接受信息
    /// </summary>
    /// <param name="info"></param>
    /// <param name="toName"></param>
    void ToClient(object info, string toName);
    void ToLogin(string name);
    void ToExit(string name);
  }
  /// <summary>
  /// 客户端发送消息
  /// </summary>
  /// <param name="info">信息</param>
  /// <param name="toName">发送给谁，""表示所有人，null表示没有接收服务器自己接收，其他表示指定某人</param>
  public delegate void SendHandler(object info, string toName);
  /// <summary>
  /// 客户端接收消息
  /// </summary>
  /// <param name="info">信息</param>
  /// <param name="toName">发送给谁，""表示所有人，null表示没有接收服务器自己接收，其他表示指定某人</param>
  public delegate void ReceiveHandler(object info, string toName);
  /// <summary>
  /// 用户信息事件
  /// </summary>
  /// <param name="name">用户名</param>
  public delegate void UserChangedHandler(string name);
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ICommand
{
  public class SwapObject : MarshalByRefObject
  {

    public event ReceiveHandler SwapServerToClient 
    {
      add { _receive += value; }
      remove { _receive -= value; }
    }
    /// <summary>
    /// 接受信息
    /// </summary>
    /// <param name="info"></param>
    /// <param name="toName"></param>
    public void ToClient(object info, string toName)
    {
      if (_receive != null)
        _receive(info, toName);
    }
    //无限生命周期 
    public override object InitializeLifetimeService()
    {
      return null;
    }

    private ReceiveHandler _receive;
  } 
}
