我用asp.net中操作IIS是编写IISVDir.dll操作IIS
使用方法：
Dim test As New IISVDir()
test.CreateVirtualDir("localhost","vdir","e:\","test")
注意：
1、web目录中的test必需存在
2、当此代码用于web中时，出错为不能创建Active组件，
修改“x:\WINNT\Microsoft.NET\Framework\v1.0.3705\CONFIG\machine.config”中的<processModel 键修改为userName="SYSTEM" password="AutoGenerate"就能解决.
