WinForm中将图片输出为字节流，读取字节流为图片

c#读取图片路径，转换为二进制的字节流

ImageConverter ic = new ImageConverter();
Object obj = ic.ConvertTo(Image.FromFile(Server.MapPath("images/0001.jpg")), typeof(byte[]));
byte[] bs = (byte[])obj;

c#读取字节流，转换成图片

PictureBox pb = new PictureBox();
pb.Image = Images.FromStream(BytesToStream(传入字节流))
private Stream BytesToStream(byte[] bytes)
{
      Stream stream = new MemoryStream(bytes);
      return stream;
}
