Asp.Net中動(dòng)態(tài)頁(yè)面轉(zhuǎn)靜態(tài)頁(yè)面 時(shí)間：2015-06-28 00:00:00 來(lái)源：IT貓撲網(wǎng) 作者：網(wǎng)管聯(lián)盟 我要評(píng)論(0)

關(guān)于在Asp.Net中動(dòng)態(tài)頁(yè)面轉(zhuǎn)靜態(tài)頁(yè)面的方法網(wǎng)上比較多。結(jié)合實(shí)際的需求，我在網(wǎng)上找了一些源代碼，并作修改。現(xiàn)在把修改后的代碼以及說(shuō)明寫(xiě)一下。

一個(gè)是一個(gè)頁(yè)面轉(zhuǎn)換的類(lèi)，該類(lèi)通過(guò)靜態(tài)函數(shù)Changfile（）來(lái)實(shí)現(xiàn)，動(dòng)態(tài)頁(yè)面到靜態(tài)頁(yè)面的轉(zhuǎn)換。
