Question

I have a method which returns a array of ByteArray:

public byte[][] Draw(ImageFormat imageFormat, ImageSize imageSize);

and I need to write it into a MemoryStream:

var byteArray = instanceName.Draw(ImageFormat.Jpeg, ImageSize.Dpi150);
MemoryStream ms = new MemoryStream(byteArray[0]);

This is working so far because the array of byteArray only ever has one element. Would someone be able to point out and provide a solution on : what would happen if the array of byteArray has more than one element?

I guess with current code I would still take the first element of the byteArray and discard the rest, but I need MemoryStream and it can not take a multi-dimensional array.

iYou will have to loop and write, something like this:

var ms = new MemoryStream();
for(var i=0; i < byteArray.Length; i++)
  ms.Write(byteArray[i], 0, byteArray[i].Length);

(I’m not sure it’s working as-is, you might have to adjust it, but it’s the principle)
