這篇文章主要介紹C#如何使用Socket實(shí)現(xiàn)服務(wù)器與多個(gè)客戶端通信,文中介紹的非常詳細(xì),具有一定的參考價(jià)值,感興趣的小伙伴們一定要看完!
成都創(chuàng)新互聯(lián)公司始終堅(jiān)持【策劃先行,效果至上】的經(jīng)營(yíng)理念,通過(guò)多達(dá)十年累計(jì)超上千家客戶的網(wǎng)站建設(shè)總結(jié)了一套系統(tǒng)有效的營(yíng)銷推廣解決方案,現(xiàn)已廣泛運(yùn)用于各行各業(yè)的客戶,其中包括:戶外休閑椅等企業(yè),備受客戶稱贊。
擴(kuò)展:由于server端是存儲(chǔ)了所有server與client的連接對(duì)象,因此我們是可以基于此demo的基礎(chǔ)上實(shí)現(xiàn)聊天系統(tǒng):
* 每當(dāng)一個(gè)與用戶發(fā)言時(shí),是由server接收到的某個(gè)用戶的發(fā)言信息的,此時(shí)服務(wù)器端可以通過(guò)循環(huán)發(fā)送該用戶發(fā)送的信息給每個(gè)已經(jīng)連接連接的用戶(排除發(fā)送者)。
