作者:leewy 
  C#關(guān)機(jī)代碼是如何實(shí)現(xiàn)的呢?當(dāng)我們?cè)趯?shí)際開(kāi)發(fā)的過(guò)程中遇見(jiàn)這樣的需求的時(shí)候我們是如何把握的呢?那么本文就向你詳細(xì)介紹C#關(guān)機(jī)代碼的實(shí)現(xiàn)過(guò)程。
 C#關(guān)機(jī)代碼的實(shí)現(xiàn)是如何的呢?我們經(jīng)常會(huì)碰到這樣的需求,那么在這方面我們是如何實(shí)現(xiàn)的呢?讓我們還是看看實(shí)際的代碼操作,希望對(duì)于你C#關(guān)機(jī)代碼的開(kāi)發(fā)有所啟示。
C#關(guān)機(jī)代碼實(shí)現(xiàn)實(shí)例:(支持Win XP下的關(guān)機(jī))

C#關(guān)機(jī)代碼的實(shí)現(xiàn)過(guò)程就向你介紹到這里,希望對(duì)你了解和學(xué)習(xí)C#關(guān)機(jī)代碼有所幫助。
