Timer函数中使用的TcpListener会产生太多线程

Question

代码：

private static TcpListener listener;
static System.Timers.Timer requestReceiver = new System.Timers.Timer(100);

在main中：

listener = new TcpListener(SERVER_IP, serverPort);
listener.Start();
requestReceiver.Elapsed += new ElapsedEventHandler(ReceiveRequest);
requestReceiver.Enabled = true;

现在我有听众的功能：

private static void ReceiveRequest(object source, ElapsedEventArgs e)
{
        try
        {
            while (true)
            {
                TcpClient tcpClient = listener.AcceptTcpClient();
                NetworkStream stream = tcpClient.GetStream();
                int requestLength = stream.Read(requestBytes, 0, requestBytes.Length);
                requestTable = (String[])ByteArrayToObject(requestBytes);

                tcpClient.Close();
             }
         }
         finally
         {
             listener.Stop();
         }
}

这段代码创建了很多线程。可能这就是它在一段时间后崩溃的原因。我该怎么做才能避免创建线程？如何暂停监听过程？为什么这段代码创建了这么多线程？
