C#同时有多个tcpclient

我遵循了msdn页面上的tcpclient和tcplistener示例：https://msdn.microsoft.com/en-us/library/bew39x2a（v=vs.110）.aspx

我正在尝试连接到我有一个tcp echo服务器的几块硬件。我可以创建一个tcpclient并连接到一个板，以毫秒的延迟发送和接收一个完整的echo。我可以以毫秒的延迟自行连接到第二板。我不能同时连接到两个板并发送带有响应的字符串，即使我只这样做一次并退出循环。

我基本上以异步客户端为例，添加了一些代码来通过按钮启动它：

    private void button1_Click(object sender, EventArgs e)
    {
        AsynchronousClient client1 = new AsynchronousClient();
        AsynchronousClient client2 = new AsynchronousClient();
        client1.Begin("192.168.1.10");
        Thread.Sleep(5000);
        client2.Begin("192.168.1.11");
    }

此代码失效。最后，我希望能够连接到我的一些硬件，每隔一秒左右发送请求，查询他们可能积累的数据。我认为我对tcp的理解还不足以使它工作，但我认为我应该能够异步地与两个客户端交谈。我尝试过用线程、任务和我能想到的任何其他东西来实现这一点，但我无法用我的应用程序同时可靠地与两台服务器进行通信。任何见解都会有所帮助。谢谢

这是我现在使用的。这样做安全吗？我还没有写任何错误处理。此外，我是一名硬件工程师，不生活在c#世界，我正在努力学习如何正确使用这种语言。
