Microsoft .NET Remoting：技术概述（二）

以下我们将举一个使用channel的例子。在这个例子中，我们将可以看到使用HTTP channel把两个应用

连接在一起是如此的简单。以下的服务器应用提供了一个服务，可将一个字符串的字母顺序反转。

Server.cs using System;

using System.IO;

using System.Runtime.Remoting;

using System.Runtime.Remoting.Channels.HTTP;

namespace RemotingSample

{

public class Reverser : MarshalByRefObject

{

public string Reverse(string text)

{

Console.WriteLine("Reverse({0})", text);

string rev = "";

for (int i=text.Length-1; i>=0; i--)

{

rev += text[i];

}

Console.WriteLine("returning : {0}", rev);

return rev;

}

}

public class TheApp

{

public static void Main()

{

file:// Create a new HTTP channel that

// listens on port 8000

HTTPChannel channel = new HTTPChannel(8000);

// ReGISter the channel with the runtime

ChannelServices.ReGISterChannel(channel);

// Expose the Reverser object from this server

RemotingServices.RegisterWellKnownType(

"server", // assembly name

"RemotingSample.Reverser", // full type name

"Reverser.soap", file:// URI

WellKnownObjectMode.Singleton // instancing mode

);

// keep the server running until

// the user presses enter

Console.WriteLine("Server.exe");

Console.WriteLine("Press enter to stop server...");
