Getting mimetype Windows

Posted by admin under .NET

This code needs permission to read from registry - so it might not be suited in a web scenario. However it's useful so here it is:



        private string MimeType(string Filename)
        {
            string mime = "application/octetstream";
            string ext = System.IO.Path.GetExtension(Filename).ToLower();
            Microsoft.Win32.RegistryKey rk = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);
            if (rk != null && rk.GetValue("Content Type") != null)
                mime = rk.GetValue("Content Type").ToString();
            return mime;
        }

In short - you just feed it with path top a file - and get back the mime type.

Ex

MimeType("f:\\theimage.jpg")   --->>> "image/jpeg"
