Question

Need MD5 hash for an in memory System.Drawing.Image

Answer 1

Thanks to the other fellows who answered. Here's what I ended up doing:

MemoryStream ms = new MemoryStream()
image.Save(ms, ImageFormat.Png);
byte[] imgBytes = ms.ToArray();

MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
byte[] hash = md5.ComputeHash(imgBytes);
string imageMD5 = BitConverter.ToString(hash).Replace("-", "").ToLower();
ms.Dispose();
