Solution 1

Do you have Byte[] (byteArray) ?

Write the byte to file directly

C#

System.IO.File.WriteAllBytes("C:\Text.jpg");  //Replace your Filepath

If you convert a byte to an image, it will be really small image. :-)

You really are asking about an array of bytes. Here is the way: you put the bytes in a memory stream and read this memory stream with System.Drawing.Image.FromStream.

C#

byte[] imageData = //...;

//...

using (System.IO.MemoryStream stream = new System.IO.MemoryStream(imageData)) {
    System.Drawing.Image image = new System.Drawing.Image.FromStream(stream);
} // stream dispose is called here implicitly

See:
http://msdn.microsoft.com/en-us/library/system.drawing.image.fromstream.aspx[^],
http://msdn.microsoft.com/en-us/library/system.io.memorystream.aspx[^].

If you want, WPF has similar methods. Please see, for example: http://forums.silverlight.net/p/44637/121951.aspx[^].
