How can I tell if a TIF is a multi-page TIF file or a multi-graph TIF file

How can I tell if a TIF is a multi-page TIF file or a multi-graph TIF file.

Can you explain what a multi-graph tif file is? And what you are trying to do?

I have found a solution

    public static bool HasMultiPageTIF(string filename)
    {
        if (!File.Exists(filename)) return false;

        try
        {
            TiffReadDefines tiffRead = new TiffReadDefines();

            tiffRead.IgnoreTags = new string[] { "ignore-layers" };

            MagickReadSettings readSettings = new MagickReadSettings(tiffRead);

            using (MagickImageCollection magimages = new MagickImageCollection())
            {
                magimages.Ping(filename, readSettings);

                if (magimages.Count > 1)
                {
                    return true;
                }
                else
                {
                    return false;
                }
            }
        }
        catch (Exception)
        {
            return false;
        }
    }
