C# Socket簡(jiǎn)單例子(服務(wù)器與客戶(hù)端通信)

1、C# Socket簡(jiǎn)單例子（服務(wù)器與客戶(hù)端通信）這個(gè)例子只是簡(jiǎn)單實(shí)現(xiàn)了如何使用 Socket 類(lèi)實(shí)現(xiàn)面向連接的通信。注意：此例子的目的只是為了說(shuō)明用套接字寫(xiě)程序的大概思路，而不是實(shí)際項(xiàng)目中的使用程序。在這個(gè)例子中，實(shí)際上還有很多問(wèn)題沒(méi)有解決，如消息邊界問(wèn)題、端口號(hào)是否被占用、消息命令的解析問(wèn)題等。下面是兩個(gè)程序的代碼，（兩個(gè)程序均為控制臺(tái)程序）注：多個(gè)TCP連接或多個(gè)應(yīng)用程序進(jìn)程可能需要通過(guò)同一個(gè) TCP協(xié)議端口傳輸數(shù)據(jù)。為了區(qū)別不同的應(yīng)用程序進(jìn)程和連接，許多計(jì)算機(jī)操作系統(tǒng)為應(yīng)用程序與TCPIP協(xié)議交互提供了稱(chēng)為套接字(Socket)的接口。先發(fā)服務(wù)端的（Server)完整代碼如下：引入命名空
