C#TCP通信问题。客户端发送的消息只能收到第一条。客户端必须断开重新连接，服务器才能再次收到信息。为何？
代码如下：
private Socket socketListener = null;
private Thread thread;
private bool flag;
private void button1_Click(object sender, EventArgs e)
{
if (btnStart.Text == "开启服务器")
{

IPHostEntry hostEntry = Dns.GetHostEntry(Dns.GetHostName());
this.socketListener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

IPAddress ipAddress = IPAddress.Parse("192.168.1.109");
int port = Int32.Parse(this.txtPoint.Text);
//hostEntry.AddressList[2].Address
IPEndPoint endPoint = new IPEndPoint(ipAddress, port);
this.socketListener.Bind(endPoint);
flag = true;
this.thread = new Thread(new ThreadStart(this.ReceiveMessage));
this.thread.Start();
btnStart.Text = "关闭服务器";
if (!txtClientMessage.InvokeRequired)
{
txtClientMessage.AppendText("服务器已打开\n\r");
}

}
else
{
this.socketListener.Close();
this.thread.Abort();
this.flag = false;
}

}


#region 接收消息

public delegate void SetTextHandle(string msg);
private void SetText(string text)
{
if (txtClientMessage.InvokeRequired)
{
SetTextHandle set = new SetTextHandle(SetText);
txtClientMessage.Invoke(set, new object[] { text });
}
else
{
this.txtClientMessage.AppendText(text);
}
}



private void ReceiveMessage()
{
while (this.flag)
{
this.socketListener.Listen(30);
Socket socket = this.socketListener.Accept();

byte[] bytesReceive = new byte[1024];
int bytesCount = socket.Receive(bytesReceive);
bool t = socketListener.Connected;
if (bytesCount > 0)
{
string message = Encoding.Default.GetString(bytesReceive) + "\n\r";
SetText(message);
}

}
}
#endregion

没注意，原来是个按钮事件，稍微修改下

C# code

private void button1_Click(object sender, EventArgs e){    if (btnStart.Text == "开启服务器")    {        IPHostEntry hostEntry = Dns.GetHostEntry(Dns.GetHostName());        this.socketListener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);        IPAddress ipAddress = IPAddress.Parse("192.168.1.109");        int port = Int32.Parse(this.txtPoint.Text);        IPEndPoint endPoint = new IPEndPoint(ipAddress, port);        this.socketListener.Bind(endPoint);        this.socketListener.Listen(30);        ThreadPool.QueueUserWorkItem(p =>        {            while (true)            {                Socket socket = this.socketListener.Accept();                this.thread = new Thread(this.ReceiveMessage);                this.thread.Start(socket);            }        });        btnStart.Text = "关闭服务器";        if (!txtClientMessage.InvokeRequired)        {            txtClientMessage.AppendText("服务器已打开\n\r");        }    }    else    {        this.socketListener.Close();        this.thread.Abort();        this.flag = false;    }}

Accept 后会有一个事件，事件参数中有一个Socket 的对像这个对像可以得到你要的功能和内容

你这样试试，
1.加一个类级变量 bool _IsEnd = false;
2.while (true)这里改成 while(!_IsEnd);记得打开连接之前，_IsEnd=false;
3.this.socketListener.Close();这句话之前，加上_IsEnd =true;
this.socketListener.Shutdown(SocketShutdown.Both);
