我建立一個客戶機/服務器應用程序來學習如何遊戲基於客戶機/服務器的作品，但應用程序似乎不能很好地工作，這裏是我的問題：如何正確構建客戶端/服務器應用程序？

爲什麼不能這樣應用程序可以」 t關閉客戶端應用程序時寫入「播放器XXX離開」
如何正確接收來自服務器的數據？（我想接收來自服務器的位置信息，以使其在客戶端）

這裏是全碼：

我*假設你的意思是「客戶/服務器」的「C/S」？這部分問題嚴重隱含，但從未明確闡述。 –

你的問題太廣泛了。對最簡單部分的簡短回答：您無法檢查客戶端狀態，因爲您的代碼卡在'AcceptTcpClient（）'調用中。你會看到，如果你使用調試器來看看代碼在做什麼。解決這類問題的常用方法是編寫異步代碼，以便在網絡I/O事件發生時響應，而不會阻止任何一個線程響應。我在最近發佈的[這個答案]（https://stackoverflow.com/a/44942011）中有一個例子。 –

解決方案：

對於傳輸客戶端運動w ith服務器，你會想要使用UDP的速度。這是經常在遊戲中傳輸數據的最有效方式。

至於你的其他問題，它最有可能不知道客戶端，可能你的連接沒有被正確關閉，因此連接必須超時才能被識別爲關閉。
