Flex与Dotnet 之 Socket

继一篇的Flex与Dotnet 之 WebService这一篇主要是写一个例子基于socket的Flex与Dotnet通讯。
很简单，两段代码。
C#代码Socket服务器
　

using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Text;

namespace MyTcpListener

Flex代码客户端

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
    <mx:Script>
        <![CDATA[
            import SocketTest.CustomSocket;
            private var socket:Socket;
             private function StartTest():void
            {
                socket = new Socket("127.0.0.1",13000);
                socket.addEventListener(Event.CONNECT, connectHandler);
                socket.addEventListener(ProgressEvent.SOCKET_DATA, socketDataHandler);
            }
            private function CloseTest():void
            {    
                if(socket!=null && socket.connected)
                {
                    trace("socket.connected:"+socket.connected);
                    socket.close();
                    trace("socket.connected:"+socket.connected);
                }
            }
            private function connectHandler(event:Event):void 
            {
                trace("connectHandler: " + event);
                socket.writeMultiByte(SendStr.text,"GB2312");
                socket.flush();
            }
            private function socketDataHandler(event:ProgressEvent):void 
            {
                trace("socketDataHandler: " + event);
                var str:String=socket.readMultiByte(socket.bytesAvailable,"GB2312");
                ReceiveStr.text = str;
            }
        ]]>
    </mx:Script>

        <mx:Text text="发送" y="11" x="18" fontWeight="bold" color="#ffffff"/>
        <mx:TextArea id="ReceiveStr" x="53" y="68"/>
        <mx:Text text="接收" y="69" x="18" fontWeight="bold" color="#ffffff"/>
        <mx:TextArea id="SendStr" y="10" x="53"/>
        <mx:Button label="Close" click="CloseTest()" x="126" y="120"/>
        <mx:Button label="Start" click="StartTest()" x="53" y="120"/>
</mx:Application>

很简单，但是做为Flex与Dotnet交互还是很常用的。
