Question

I am writing an installer class for my web service. In many cases when I use WMI (e.g. when creating virtual directories) I have to know the siteId to provide the correct metabasePath to the site, e.g.:

metabasePath is of the form 'IIS://<servername>/<service>/<siteID>/Root[/<vdir>]' for example 'IIS://localhost/W3SVC/1/Root'  

How can I look it up programmatically in C#, based on the name of the site (e.g. for ‘Default Web Site’)?

Here is how to get it by name. You can modify as needed.

public int GetWebSiteId(string serverName, string websiteName) {   int result = -1;    DirectoryEntry w3svc = new DirectoryEntry(                       string.Format('IIS://{0}/w3svc', serverName));    foreach (DirectoryEntry site in w3svc.Children)   {     if (site.Properties['ServerComment'] != null)     {       if (site.Properties['ServerComment'].Value != null)       {         if (string.Compare(site.Properties['ServerComment'].Value.ToString(),                               websiteName, false) == 0)         {             result = int.Parse(site.Name);             break;         }       }     }   }    return result; }
