Question

我正在构建一个可以与游戏服务器通信和发送命令的应用程序。在游戏世界中，我们称之为远程控制台的“rcon”，但实际上它只是一个telnet会话。身份验证成功后，可以向服务器发出文本命令，并将文本响应发送回客户端。

服务器管理员/所有者经常运行多个游戏服务器，并且每个服务器都有自己独特的IP地址，端口和放大器。密码。我希望我的应用程序循环遍历服务器的列表/数组/数据表/字典（或任何方法最好），连接并验证每个服务器，然后以某种方式存储该连接，以便将来可以将命令发送给它（没有必须再次连接和验证）

以下是我用于单个服务器的代码。我存储了TcpClient（客户端）＆amp; NetworkStream（stm）作为全局对象，使连接/会话保持对服务器开放。对于我来说，使用多个服务器执行此操作的最佳方法是什么，因为每个服务器都有自己的TcpClient＆amp;的NetworkStream？

我是否有办法存储每个TcpClient（客户端）＆amp; NetworkStream（stm）在数组，字典还是什么？我完全迷失了如何处理这个问题。
