停止IIS站点的代码（不是停IISAdmin服务)

        public void StopWebSite()
        {
            System.DirectoryServices.DirectoryEntry WebSite = new System.DirectoryServices.DirectoryEntry("IIS://localhost/w3svc/1");
            WebSite.Invoke("Stop", new object[] { });   
        }

        public void StartWebSite()
        {
            System.DirectoryServices.DirectoryEntry WebSite = new System.DirectoryServices.DirectoryEntry("IIS://localhost/w3svc/1");
            WebSite.Invoke("Start", new object[] { });
        }
