how to get the application pool name for a specific website IIS6 programmatically? C#

Question

how to get the application pool name for a specific website IIS 6 programmatic using C#

EDIT: I already used the methods of DirectoryServices namespace but the application pool name isn't retrieved correctly unless it was explicitly set by using the same code. Which means if u add a website manually using the iis manager and set an application pool, those codes won't work (it will always return DefaultAppPool) more over when I create an application using sharepoint and set a different appPool those methods dont work.

I don't agree with you. I coded up a test app and I get the correct AppPool name from it, even if I set the AppPool manually using IIS Manager.

To make sure, I have tested once, name name was ok; then, I popep up the IIS Manager, changed the AppPool, executed iisreset, and ran the test app again - the AppPool name I got was correct again. I don't how your code looked like, but mine is like this:

using System;
using System.IO;
using System.DirectoryServices;

class Class
{
    static void Main(string[] args)
    {
        DirectoryEntry entry = FindVirtualDirectory("<Server>", "Default Web Site", "<WantedVirtualDir>");
        if (entry != null)
        {
            Console.WriteLine(entry.Properties["AppPoolId"].Value);
        }
    }

    static DirectoryEntry FindVirtualDirectory(string server, string website, string virtualdir)
    {
        DirectoryEntry siteEntry = null;
        DirectoryEntry rootEntry = null;
        try
        {
            siteEntry = FindWebSite(server, website);
            if (siteEntry == null)
            {
                return null;
            }

            rootEntry = siteEntry.Children.Find("ROOT", "IIsWebVirtualDir");
            if (rootEntry == null)
            {
                return null;

            }

            return rootEntry.Children.Find(virtualdir, "IIsWebVirtualDir");
        }
        catch (DirectoryNotFoundException ex)
        {
            return null;
        }
        finally
        {
            if (siteEntry != null) siteEntry.Dispose();
            if (rootEntry != null) rootEntry.Dispose();
        }
    }

    static DirectoryEntry FindWebSite(string server, string friendlyName)
    {
        string path = String.Format("IIS://{0}/W3SVC", server);

        using (DirectoryEntry w3svc = new DirectoryEntry(path))
        {
            foreach (DirectoryEntry entry in w3svc.Children)
            {
                if (entry.SchemaClassName == "IIsWebServer" &&
                    entry.Properties["ServerComment"].Value.Equals(friendlyName))
                {
                    return entry;
                }
            }
        }
        return null;
    }
}

Sorry for my lousy english.
Hope I've helped.
