利用IIS7自带类库管理IIS现在变的更强大更方便，而完全可以不需要用DirecotryEntry这个类了(乐博网中很多.net管理iis6.0的文章都用到了DirecotryEntry这个类 )，Microsoft.Web.Administration.dll位于IIS的目录（%WinDir%\\System32\\InetSrv）下，使用时需要引用，它基本上可以管理IIS7的各项配置。

这个类库的主体结构如下：

这里只举几个例子说明一下基本功能，更多功能请参考MSDN。

string SiteName="乐博网"; //站点名称 string BindArgs="*:80:"; //绑定参数，注意格式 string apl="http"; //类型 string path="e:\\乐博网"; //网站路径 ServerManager sm = new ServerManager(); sm.Sites.Add(SiteName,apl,BindArgs,path); sm.CommitChanges();

修改站点

Site site=sm.Sites["newsite"]; site.Name=SiteName; site.Bindings[0].EndPoint.Port=9999; site.Applications[0].VirtualDirectories[0].PhysicalPath=path; sm.CommitChanges();

删除站点

Site site=sm.Sites["乐博网"]; sm.Sites.Remove(site); sm.CommitChanges();
