convert array of bitmaps to array of bytes

Question

I have an array of Bitmaps that I'm trying to convert into an array of bytes where each index of the byte array represents a Bitmap. I'm having some trouble figuring out how to do this. If anyone has a suggestion, let me know. Thanks!

private void ConvertBitmapToBytes(Bitmap[] BitmapArray) { byte[][] BitmapBytes = new byte[BitmapArray.Length][]; ImageConverter convert = new ImageConverter(); for (int i = 0; i < BitmapArray.Length; i++) { BitmapBytes[i] = new byte[BitmapArray.Length]; BitmapBytes[i][i] = convert.ConvertTo(BitmapArray[i], typeof(byte[])); } }

Try this:

public byte[] ImageToByte(Bitmap image){ using (MemoryStream ms = new MemoryStream()) { // Convert Image to byte[] image.Save(ms, ImageFormat.Bmp); byte[] imageBytes = ms.ToArray(); return imageBytes; } }

And then, your code will become this:

private void ConvertBitmapToBytes(Bitmap[] BitmapArray) { byte[][] BitmapBytes = new byte[BitmapArray.Length][]; for (int i = 0; i < BitmapArray.Length; i++) { BitmapBytes[i] = ImageToByte(BitmapArray[i]); } }

Hope it helps
