Flash客户端与C#服务器通讯的消息接发问题

C#控制台程序代码：－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Text;

namespace ConsoleApplication6
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
string data;
data="";
IPEndPoint ipep=new IPEndPoint(IPAddress.Parse("127.0.0.1"),9050);
Socket newsock= new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
newsock.Bind(ipep);
newsock.Listen(10);
Console.WriteLine("Wait for a connect ...");
Socket client = newsock.Accept();
IPEndPoint newclient = (IPEndPoint)client.RemoteEndPoint;
Console.WriteLine("Connected with {0} at port {1}",newclient.Address,newclient.Port);

NetworkStream ns = new NetworkStream(client);
StreamReader sr = new StreamReader(ns);
StreamWriter sw = new StreamWriter(ns);
string welome="Welcome to ,my test server";
sw.WriteLine(welome);
sw.Flush();
sw.Write("<LOGINREPLY login='1' msg='Msg'/>");
sw.Flush();
while(true)

try
{
data=sr.ReadLine();
}
catch(IOException e)

{
Console.WriteLine(e.ToString());
Console.ReadLine();
}
Console.WriteLine(data);
sw.WriteLine("<LOGINREPLY msg='Msg'/>");
sw.Flush();
}
Console.WriteLine("Disconnect form {0} ",newclient.Address);
sw.Close();
sr.Close();
ns.Close();
}
}
}
Flash客户端的代码：－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
Flash第一帧的帧上加脚本：
// Create a new XMLSocket object
sock = new XMLSocket();
// Call its connect() method to establish a connection with port 1024
// of the server at the URL
// Define a function to assign to the sock object that handles
// the server?s response.If the connection succeeds, send the
// myXML object.If it fails, provide an error message in a text
// field.
function onSockConnect(success){
if (success){
trace("Connect to server success!/n");
} else {
msg="There has been an error connecting to "+serverName;
}
}
sock.onXML=function(xmlText){
trace("Get xmlText from server");
}
sock.onData=function(data){
trace("Get Msg from server");
}
// Assign the onSockConnect() function to the onConnect property
sock.onConnect = onSockConnect;
sock.connect("127.0.0.1", 9050);
trace("connect...");
stop();

Flash舞台上放一个向服务器发送信息的按钮，代码如下：
on(release){
sock.send("Hello! 01\n");
sock.send("Hello! 02\n");
}
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
本地已经测试通过，C#能接收到Flash发送的信息，但是flash却收不到C#服务器发回的信息。

请各位一起帮忙看一下！谢谢！
