复制代码 代码如下:

///图片转二进制

private byte[] convertByte(Image img)

{

MemoryStream ms = new MemoryStream();

img.Save(ms, img.RawFormat);

//byte[] bytes = new byte[ms.Length];

//ms.Read(bytes, 0, Convert.ToInt32(ms.Length));

//以上两句改成下面两句

byte[] bytes = ms.ToArray();

ms.Close();

return bytes;

}

///二进制生成图片

private Image convertImg(byte[] datas)

{

MemoryStream ms = new MemoryStream(datas);

Image img = Image.FromStream(ms, true);

ms.Close();

return img;

}
