Question

我正在尝试为每个连接到服务器的人创建一个数组。

然而，当服务器收到信息时，连接有效，我无法知道是谁发送了这些信息。

我如何知道谁是发送信息的“客户”列表的索引？

查看代码：

基本定义

public string Ip { get; set; }
public Socket Ansyc { get; set; }
public int Index { get; set; }
public int Id { get; set; }
public UserConnection(Socket t, int i) { Ansyc = t; Id = i; }

任何人都有提示或解决方案吗？

Answer 1

您的StateObject类应包含识别客户端所需的所有必要上下文。您通常甚至不需要查阅客户端列表来处理单个客户端的单独I / O操作，因为StateObject应该足够了。

如果没有a more complete code example，我就不能具体了。
