服务器和客户端连接之间的通信C＃

我正在为我的学校项目做些事情，它需要我构建一个允许来自服务器（侦听器）和客户端的通信的C＃应用程序。问题是，我已经这样做了，但它根本不起作用，它会抛出太多的错误来纠正，而且肯定是严重的编码，我从来没有做过这种草率的事情。服务器和客户端连接之间的通信C＃

我还希望很多客户端能够同时访问服务器，因此客户端列表中的活动人员。我在网上看到一个例子，但对于我试图实现的任务而言，这太复杂了。我只想与客户端和服务器进行简单的文本通信，并在需要时发送信息。我不希望它卡在一个while循环等待信息发送& whatnot。

对不起，如果我不好解释它。谢谢。

找到一些很好的文章发表你试过了什么。否则它是太宽泛的问题。 – Divisadero

这个问题需要认真的工作。请准确显示您尝试过的内容以及您遇到的无法解决的错误/问题。 – nodots

** A）**为什么您使用两个线程来读取数据？这可能会导致严重的问题。要么摆脱'Thread1'或'retrieveData'。 ** B）**检查'clientCon.Connected == null'是无用的，因为'Boolean'值不能为空。 –

从你解释什么，我真的不能弄清楚你想要什么，但我从猜测让我们说这取决于你想去的技术。我会建议使用WCF Windows Communication Foundation。你可以在.NET Foundation，Tutorial to get started
