I have this exception when I will try running my site on the iis version 10 on the windows server

  //try
           // {
                foreach (DirectoryEntry site in w3svc.Children)
                {
                    if (site.Properties["ServerComment"] != null)
                    {
                        if (site.Properties["ServerComment"].Value != null)
                        {
                            site_name = site.Properties["ServerComment"].Value.ToString();


                            if (site_name.Equals(websiteName + app))

                            //     if (string.Compare(site.Properties["ServerComment"].Value.ToString(), websiteName, false) == 0)//origional condition
                            {
                                result = true;
                                IisWebSite iss = new IisWebSite();
                                iss.BINDING = site.Properties["ServerBindings"].Value.ToString();
                                iss.NAME = site.Properties["ServerComment"].Value.ToString();
                                sitelist.Add(iss);
                                // re = site.Properties["ServerComment"].Value.ToString();
                            }
                        }
                     }
                }
