使用套接字測試服務器

Question

我想測試我的服務器，所以我在我的計算機中執行N個客戶端。問題是第一個客戶端工作，但其他人的連接丟失，他們的套接字立即關閉!!!!!!任何想法如何解決這個問題？

這是我的代碼：

       sock.Send(data1);Invoke((operation)effectuer, s);

     sock.Send(data1); 
     Invoke((operation)effectuer, s); 
     }

} 

任何想法如何，我可以在同一臺機器上使用相同的插槽執行N個客戶端？

在服務器代碼中，您只需撥打sock = sock.Accept();一次。將此代碼移至一個線程並用while(true)包圍它。您可能還想在其他線程中處理客戶端的請求。
