byte c# buffer 存储 java

Bitmap => byte[]

Bitmap b = new Bitmap( "test.bmp ");
MemoryStream ms = new MemoryStream();
b.Save(ms,System.Drawing.Imaging.ImageFormat.Bmp);
byte[] bytes= ms.GetBuffer(); //byte[] bytes= ms.ToArray(); 这两句都可以，至于区别么，下面有解释
ms.Close();

byte[] => Bitmap
byte[] bytelist=bytes;
MemoryStream ms1 = new MemoryStream(bytelist);
Bitmap bm = (Bitmap)Image.FromStream(ms1);
ms1.Close();
