C# 使用套接字测试服务器
我想测试我的服务器,所以我在我的计算机上执行N个客户端。问题是,第一个客户端工作,但其他客户端的连接丢失,其套接字立即关闭!!!!!!你知道我该如何解决这个问题吗 这是我的代码: 服务器:C# 使用套接字测试服务器,c#,sockets,client,C#,Sockets,Client,我想测试我的服务器,所以我在我的计算机上执行N个客户端。问题是,第一个客户端工作,但其他客户端的连接丢失,其套接字立即关闭!!!!!!你知道我该如何解决这个问题吗 这是我的代码: 服务器: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text;

知道我如何在同一台机器上用同一个套接字执行N个客户端吗?在服务器代码中调用
sock=sock.Accept()代码>仅一次。将此代码移动到线程并用while(true)
将其环绕。您可能还希望在其他线程中处理客户端的请求。在服务器代码中,您调用sock=sock.Accept()代码>仅一次。将此代码移动到线程并用while(true)
将其环绕。您可能还希望在其他线程中处理客户端的请求。是否使用goto
s?我想我可能会哭。goto
是从循环结束到循环开始的吗?是的,goto这样做,但不建议我可以替换它。您使用的是goto
