How to go from NSData to byte[]

Question

If I have image data in an NSData, extracted from the image as follows, how do I convert this NSData object into a byte array?

NSData data = NSData.FromUrl(NSUrl.FromString(urlString));

Answer 1

NSData data = NSData.FromUrl(NSUrl.FromString(urlString));

byte[] dataBytes = new byte[data.Length];

System.Runtime.InteropServices.Marshal.Copy(data.Bytes, dataBytes, 0, Convert.ToInt32(data.Length));
