使用ASP.Net來操作IIS,可以達到創建虛擬目錄,虛擬站點,刪除虛擬目錄,列表等等功能.
關鍵:ASP.Net的用戶權限不足以操作IIS,要授予一個高點的權限.
方法1,在web.config文件中加入這一行<identity impersonate="true" />,不過有風險.
方法2,使用假冒,我就是用這一方法,但還是有風險,
其它方法,略

今天整理代碼的時候發現一直對母版頁內ContentPlaceHolder的引用，使用的控件查找方式：
程序代碼
this.Master.FindControl("SideBarBox") as ContentPlaceHolder
這樣做的原理大概就是通過在母版頁內查找控件ID，然後通過反射進行調用的。反射本身就是極其影響效率的一種方式，特別是在頁面訪問量特別大的時候，不做緩存處理，那麼對於服務器來說是一場噩夢。雖然還有生成靜態頁面的方法，但是現在談的是如何使用強類型引用母版頁子控件。
於是開始做實驗，首先在母版頁聲明： 程序代碼
public static ContentPlaceHolder sideBarBox;
然後在protected void Page_Load(object sender, EventArgs e)裡面將頁面的ContentPlaceHolder引用給sideBarBox。結果運行出錯，沒有給對象賦值。
仔細想了一下，估計是子頁的Page_Load比母版頁的Page_Load要先處理，所以導致為空。看了一下MSDN，確實是這樣的，頁面的加載順序如下：
