c#TCP通信服务端获取客户端数据流问题，怎么才能获取数据流？下面的有啥问题

public Socket SocketClient;
//TcpClient TcpClient;
TcpListener Listener;
NetworkStream NetStream;//网络流
StreamReader ServerReader;//服务器读写
StreamWriter ServerWriter;
Thread Thd;//线程
private void btnBeginServer_Click_1(object sender, EventArgs e)
{

Thd = new Thread(new ThreadStart(BeginLister));//创建线程
Thd.Start(); //启动线程
} // 按键 打开服务器 执行函数
public void BeginLister()
{
while (true)
{
try
{
IPAddress [] Ips=Dns.GetHostAddresses("127.0.0.1");//本机IP定义
string GetIp=Ips[0].ToString ();
Listener = new TcpListener(IPAddress.Parse(GetIp), 8888); // 监听
Listener.Start();//开始监听
CheckForIllegalCrossThreadCalls = false;
btnBeginServer.Enabled=false ;
this.Text="服务器已经开启......";
// NetStream = TcpClient.GetStream();
SocketClient = Listener.AcceptSocket();
NetStream = new NetworkStream(SocketClient);
ServerWriter = new StreamWriter(NetStream);
ServerReader = new StreamReader(NetStream);

//ServerWriter = new StreamWriter(NetStream);

if (SocketClient.Connected) // 监听 ScoketClient
{
MessageBox.Show("客户端连接成功!", "服务器消息", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
catch
{
}// 不做处理 继续测试监听
// Listener.Stop();
}
}

public void GetMessage()
{
if (NetStream != null && NetStream.DataAvailable) // 网络流 非空 或者数据可用
{
//NetStream = TcpClient.GetStream();
X = NetStream.ToString();
MessageBox.Show(X);

}
最后messagebox显示是什么意思，，，就是想用X接受客户端来的一个字符，，，

NetworkStream.ToString()这个方法是用来显示NetworkStream完整类名称的~其实就是Object.ToString()~
你要获得NetworkStream的内容自然要读取数据留里的信息然后转码~
假设你用的是ASCII码传输
const int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
int readBytes = 0;
try
{
readBytes = NetStream.Read(buffer, 0, bufferSize);
string str = Encoding.ASCII.GetString(buffer).Substring(0, readBytes);
MessageBox.Show(str);
}
