測試HttpListener監聽請求----處理WebSocketRequest

測試HttpListener監聽請求，代碼如下：

測試結果如下：

 public class Program
    {
        static void Main(string[] args)
        {
            #region  #region 測試TestHttpListener
            TestHttpListenerWebSocket();
            #endregion
            Console.Read();
        }
    }
