有人可以向我解释c＃中单个客户端服务器和多客户端服务器之间的区别吗？
如果我想同时与许多客户建立一个聊天室，我不确定我是否理解正确，但是我们只为每个客户分配新的IP并且服务器会读取它们吗？
这是客户端代码

如果需要，我也可以发布服务器代码，讲师说他至少会欣赏这个尝试。
好的，所以我无法对其进行格式化，所以这里是服务器代码https://pastebin.com/bzhr20Qk
答案 0 :(得分：0)
从根本上说没有区别;服务器应用程序的性质是：
有趣的是：你如何处理这种连接？如果您只期望一个客户端，您可以在一个线程中执行所有操作：
如果您希望低连接数，则可以提供每个连接的线程数：
with（每个连接）
但是，对于任何非平凡的事情，每个连接的线程根本不起作用;你需要开始考虑异步代码和IO回调，共享缓冲区以及各种疯狂。很难做对。来源：目前正在为452,256个TCP / IP连接提供服务。
回答具体问题：
但是我们只为每个客户端分配新的IP并且服务器会读取它们吗？
不，客户端IP是客户端IP是客户端IP。客户端连接到侦听器端口，然后在服务器上，侦听器将移交到临时端口上的已建立的 TCP连接。你通常不需要担心这一点，它是自动处理的。但端口号在实际连接之间有所不同。
