asp.net利用RAR實(shí)現(xiàn)文件壓縮解壓縮
作者：清清月兒

如果服務(wù)器上安裝了RAR程序，那么asp.net可以調(diào)用RAR實(shí)現(xiàn)文件壓縮與解壓縮。
不過(guò)要注意的是，由于Web程序不能直接調(diào)用客戶端的程序（除非用ActiveX，ActiveX幾乎被廢棄），所以如果要想實(shí)現(xiàn)讓用戶把本地文件用網(wǎng)頁(yè)解壓縮只有把文件上傳到服務(wù)器上再調(diào)用服務(wù)器上的RAR壓縮，同理要解壓縮本地的RAR文件可以把文件上傳到服務(wù)器解壓再拿回來(lái)。
本文講怎么在服務(wù)器端的目錄解壓縮文件！
