//假如虚拟目录名为"Webtest"，先在项目中引用
//System.DirectoryServices.dll，再
using System.DirectoryServices;
protected System.DirectoryServices.DirectoryEntry dirroot;
1、添加新的虚拟目录
DirectoryEntry newVirDir = dirroot.Children.Add("Webtest","IIsWebVirtualDir");
newVirDir.Invoke("AppCreate",true);
newVirDir.CommitChanges();
dirroot.CommitChanges();
2、更改虚拟目录属性
//虚拟目录的属性较常用的有:AccessRead,AccessWrite,AccessExecute,AccessScript,DefaultDoc,EnableDefaultDoc,Path等
DirectoryEntry Dirport = dirroot.Children.Find("Webtest","IIsVirtualDir");
Dirport .Properties["AccessRead"][0] = true;
3、删除虚拟目录
DirectoryEntry Dirport = dirroot.Children.Find("Webtest","IIsVirtualDir");
Dirport.Invoke("AppDelete",true);
dirroot.CommitChanges();
或者：
object[] part = new object[2];
part[0] = "IIsWebVirtualDir";
part[1] = "Webtest";
dirroot.Invoke("Delete",part);
dirroot.CommitChanges();
按照这样写程序，得到结果说
