C#: Converting an image to Base64 / Data URI scheme

gistfile1.cs

private void B64Encode()
{
        Image a = new Bitmap( @".../path/to/image.png" );
                        
        using ( MemoryStream ms = new MemoryStream() )
        {
                // Convert Image to byte[]
                a.Save( ms, a.RawFormat );
                byte[] imageBytes = ms.ToArray();

                // Convert byte[] to Base64 String
                this.richTextBox1.Text = "<img src=\"data:image/png;base64," + Convert.ToBase64String( imageBytes ) + "\"/>";
                                
        }
                        
}

in some of browsers Data URL have limitations
and converting to base64 gets long time for large files
how can i convert bytes to image without Data URL?
