using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Fleck;

namespace WebSocketDemo
{
    /**
     * WebSocket通讯实例

    class Program
    {
        static void Main(string[] args)

                    {
                        Console.WriteLine("连接打开Open!");
