find mime types for newly added extensions

as shown here its possible to get the "default" IIS mime types from HKEY_Classes_Root. However when I register a new type I cannot find the entry - does anyone know how I get read all IIS registered mime types progamatically ?

Sorry to answer my own question but the answer posted here (shown below) resolves this for both IIS 6 & 7

         NameValueCollection map = new NameValueCollection();
            using (DirectoryEntry entry = new DirectoryEntry("IIS://localhost/MimeMap"))
            {
                PropertyValueCollection properties = entry.Properties["MimeMap"];
                Type t = properties[0].GetType();

                foreach (object property in properties)
                {
                    BindingFlags f = BindingFlags.GetProperty;
                    string ext = t.InvokeMember("Extension", f, null, property, null) as String;
                    string mime = t.InvokeMember("MimeType", f, null, property, null) as String;
                    map.Add(ext, mime);
                }
            }

You may have to add it in IIS.

http://technet.microsoft.com/en-us/library/cc725608(WS.10).aspx

Update

You could try the DirectoryServices API:

public static string GetMimeTypeFromExtension(string extension)
{
    using (DirectoryEntry mimeMap = 
           new DirectoryEntry("IIS://Localhost/MimeMap"))
    {
        PropertyValueCollection propValues = mimeMap.Properties["MimeMap"];

        foreach (object value in propValues)
        {
                IISOle.IISMimeType mimeType = (IISOle.IISMimeType)value;

                if (extension == mimeType.Extension)
                {
                        return mimeType.MimeType;
                }
        }

        return null;

    }
}

Can I setup an IIS MIME type in .NET?
