C#實(shí)現(xiàn)在線更新軟件

更新時(shí)間：2015年05月25日 15:11:16 投稿：hebedich

winform程序相對(duì)web程序而言，功能更強(qiáng)大，編程更方便，但軟件更新卻相當(dāng)麻煩，要到客戶端一臺(tái)一臺(tái)地升級(jí)，面對(duì)這個(gè)實(shí)際問題，在最近的一個(gè)小項(xiàng)目中，本人設(shè)計(jì)了一個(gè)通過軟件實(shí)現(xiàn)自動(dòng)升級(jí)技術(shù)方案，彌補(bǔ)了這一缺陷，有較好的參考價(jià)值

通過某些手段后臺(tái)更新軟件。首先你要有一個(gè)放置新版本信息的網(wǎng)站
