C# 图片与二进制转换的简单实例

///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;
}
