Convert image to binary?

Question

I have an image (in .png format), and I want this picture to convert to binary.

How can this be done using C#?

Answer 1

System.Drawing.Image image = System.Drawing.Image.FromFile("filename");
byte[] buffer;
MemoryStream stream = new MemoryStream();
image.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);

buffer = stream.ToArray(); // converted to byte array
stream = new MemoryStream();
stream.Read(buffer, 0, buffer.Length);
stream.Seek(0, SeekOrigin.Begin);
System.Drawing.Image img = System.Drawing.Image.FromStream(stream);
