IIS : Getting Physical Path for Virtual Directory in .NET

Here is a C# code sample of how to use System.DirectoryServices in .NET to get the physical path for IIS virtual directory.

class Class1
{
    [STAThread]
    static void Main(string[] args)
    {
        string serverComment = "Default Web Site";
        string iisHost = "IIS://LocalHost";
        string siteName = GetIISSiteName(iisHost, serverComment);


        Console.WriteLine(siteName);
        if(siteName.Equals(String.Empty))
        {
            Console.WriteLine("Site not found.");
        }
        else
        {
            // Get the physical path for http://localhost/testemail
            string path = GetVirtualDirPath(iisHost, siteName, "testemail");

            if(path.Equals(String.Empty))
                Console.WriteLine("VD not found.");
            else
                Console.WriteLine(path);
        }

        Console.WriteLine("done");
        Console.ReadLine();
    }


    static string GetIISSiteName(string iisHost, string serverComment)
    {
        string adsiPath = iisHost + "/W3SVC";
        DirectoryEntry entry = new DirectoryEntry(adsiPath);
        foreach (DirectoryEntry site in entry.Children)
        {
            if (site.SchemaClassName == "IIsWebServer" &&
                site.Properties["ServerComment"].Value
                .ToString().Equals(serverComment))
            {
                return site.Name;
            }
        }

        return "";
    }


    static string GetVirtualDirPath(string iisHost,
                                    string siteName, string vdName)
    {
        string adsiPath = iisHost + "/W3SVC/" + siteName + "/Root/" + vdName;

        try
        {
            DirectoryEntry entry = new DirectoryEntry(adsiPath);
            return entry.Properties["Path"].Value.ToString();
        }
        catch(Exception ex)
        {
            // If Virtual Directory is not found,
            // it will throw exception.
            return "";
        }

        return "";
    }
}
