请问怎样把一个Bitmap对象转化为 byte[]?

[newball]

例如以下,b怎样转化为 byte[]? 先谢谢了.

Bitmap b=new Bitmap(800,600);
graphics = Graphics.FromImage(b);
.........
graphics.DrawImage(b,new Rectangle(10,10,b.Width,b.Height));

VB版本
Dim ms As MemoryStream
ms = New MemoryStream
b.Save(ms, ImageFormat.Jpeg)
Dim imageByteArray(ms.Length) As Byte
ms.Position = 0
ms.Read(imageByteArray, 0, Convert.ToInt32(ms.Length))

Bitmap b = xxxxxxx; // TODO: u code here

System.IO.MemoryStream ms = new MemoryStream();
b.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);

byte[] bt = ms.GetBuffer();
