Image 和byte[]之间的转换

1.Image 转 byte[]

public byte[] GetByteByImage(Image image)
{
  byte[] bt = null;
  try
  {
    if (!image.Equals(null))
    {
      MemoryStream ms = new MemoryStream();
      Bitmap bmp = new Bitmap(image);
      bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
      bt = new byte[ms.Length];
      ms.Position = 0;
      ms.Read(bt, 0, Convert.ToInt32(bt.Length));
      bmp.Dispose();
      ms.Dispose();
      ms.Close();
    }
  }
  catch (Exception ex)
  {
    throw ex;
  }
  return bt;
}

2.byte[] 转Image

public Image GetImageByByte(byte[] imageBytes)
{
  Image image = null;
  try
  {
    MemoryStream ms = new MemoryStream(imageBytes);
    ms.Write(imageBytes, 0, imageBytes.Length);
    image = Image.FromStream(ms, true);
    ms.Dispose();
    ms.Close();
  }
  catch (Exception ex)
  {
    throw ex;
  }
  return image;
}
