Is there any way ti check for the type of a file. I mean, I want to check if a file is an Image File or a PDF or XPS file. I have written a Method for the Image:

        public static bool IsImageFile(string file)
        {
            bool isImageFile = false;
            if (FileManager.FileExist(file))
            {
                try
                {
                    if ((new Bitmap(file)) != null) isImageFile = true;
                }
                catch
                {
                }
            }

            return isImageFile;
        }

It creates a new Bitmap() so if it is a big image the method should be very slow, and I only want to check it.

Any Idea?

Thanks.
