ASP.NET对IIS中的虚拟目录进行操作的代码

//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();
