c#进程间通讯方案之IPC通道

转载：http://www.cnphp.info/csharp-ipc-channel-remoting.html

最近一直纠结与使用多进程还是多线程来构建程序。多线程的方法似乎不错，但是一个进程可承受的线程数有有限的，并且由于每个线程都与UI有着些许关系，线程的工作大多数时间浪费在阻塞上了，效率实在不是很高。

笔者遂在google上搜索进程间通讯的方案。发现有很多种，其中IPC通道似乎是个不错的选择，支持本机的进程间通讯，可以作为备选方案之一，下面介绍以下基本的编程方法，以作备忘。

首先建立一个IPC通讯中使用的对象,其中MarshalByRefObject 是必须的

 

   1:  using System;

   2:   

   3:  namespace Ipctest

   4:  {

   5:      public class test:MarshalByRefObject

   6:      {

   7:          private int iCount = 0;

   8:          public int count()

   9:          {

  10:              iCount++;

  11:              return iCount;

  12:          }

  13:   

  14:          public int Add(int x)

  15:          {

  16:              iCount += x;

  17:              return iCount;

  18:          }

  19:      }

  20:  }

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

接着建一个服务端控制台程序

   1:  using System;

   2:  using System.Runtime.Remoting;

   3:  using System.Runtime.Remoting.Channels;

   4:  using System.Runtime.Remoting.Channels.Ipc;

   5:   

   6:  namespace Ipctest

   7:  {

   8:      class Program

   9:      {

  10:          static void Main(string[] args)

  11:          {

  12:             IpcChannel serverchannel = new IpcChannel("testchannel");

  13:              ChannelServices.RegisterChannel(serverchannel,false);

  14:              RemotingConfiguration.RegisterWellKnownServiceType(typeof(test), "test", WellKnownObjectMode.Singleton);

  15:              Console.WriteLine("press Enter to exit");

  16:              Console.ReadLine();

  17:              Console.WriteLine("server stopped");

  18:          }

  19:      }

  20:  }

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

最后是客户端控制台程序

   1:  using System;

   2:  using System.Runtime.Remoting;

   3:  using System.Runtime.Remoting.Channels;

   4:  using System.Runtime.Remoting.Channels.Ipc;

   5:   

   6:  namespace Ipctest

   7:  {

   8:      class Program

   9:      {

  10:          static void Main(string[] args)

  11:          {

  12:              IpcChannel tcc = new IpcChannel();

  13:              ChannelServices.RegisterChannel(tcc,false);

  14:              WellKnownClientTypeEntry remotEntry = new WellKnownClientTypeEntry(typeof(test), "ipc://testchannel/test");

  15:              RemotingConfiguration.RegisterWellKnownClientType(remotEntry);

  16:   

  17:              test st = new test();

  18:              Console.WriteLine("{0},{1}",st.count(),st.Add(1));

  19:              Console.ReadLine();

  20:          }

  21:      }

  22:  }

在测试的过程中会发现第一次调用客户端输出结果：

1,2

第二次输出结果

3,4

……

结果是比较符合要求的。

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;

}
