[C#]image與byte數組的互相轉換

//image to byte[]

MemoryStream ms=new MemoryStream();

byte[] imagedata=null;

pictureBox1.Image.Save(ms,System.Drawing.Imaging.ImageFormat.Gif );

imagedata=ms.GetBuffer ();

//byte[] to image

ms = New IO.MemoryStream(by)

img = Drawing.Image.FromStream(ms) 

正在做這個，放在這邊留着以後參考
