C# 在WinC窗体中使用套接字连接在服务器端显示多个客户端名称#
在Windows窗体应用程序C#中,我使用套接字连接将多个客户端连接到单个服务器,并且我可以将多个客户端的号码发送到单个服务器。但问题是,在服务器上,我无法区分哪个客户端正在发送哪个号码,因此我需要在服务器端应用程序上以不同的方式显示C# 在WinC窗体中使用套接字连接在服务器端显示多个客户端名称#,c#,.net,winforms,C#,.net,Winforms,在Windows窗体应用程序C#中,我使用套接字连接将多个客户端连接到单个服务器,并且我可以将多个客户端的号码发送到单个服务器。但问题是,在服务器上,我无法区分哪个客户端正在发送哪个号码,因此我需要在服务器端应用程序上以不同的方式显示client_1、client_2、client_3等等。请让我知道怎样会更好 服务器(在OnDataReceived()方法中,如何更改它?) 使用系统; 使用System.Collections.Generic; 使用系统组件模型; 使用系统数据; 使用系统图;
