C#網(wǎng)絡(luò)編程服務(wù)器端程序?qū)崿F(xiàn)源碼淺析
C#網(wǎng)絡(luò)編程服務(wù)器端程序?qū)崿F(xiàn)源碼是怎么樣的呢?讓我們來看看其中重要的一部分:
由于在此次程序中我們采用的結(jié)構(gòu)是異步阻塞方式,所以在實(shí)際的程序中,為了不影響服務(wù)器端程序的運(yùn)行速度,我們在程序中設(shè)計(jì)了一個(gè)線程,使得對網(wǎng)絡(luò)請求偵聽,接受和發(fā)送數(shù)據(jù)都在線程中處理,請?jiān)谙旅娴拇a中注意這一點(diǎn),下面是C#網(wǎng)絡(luò)編程服務(wù)器端程序的完整代碼:
