文件转换成字节，代码如下：

 protected static byte[] GetByte(string strFilePath)
    {
        // 以二进制方式读文件
        FileStream fsMyfile = new FileStream(strFilePath, FileMode.Open, FileAccess.ReadWrite);
        // 创建一个二进制数据流读入器，和打开的文件关联
        BinaryReader brMyfile = new BinaryReader(fsMyfile);
        // 把文件指针重新定位到文件的开始
        brMyfile.BaseStream.Seek(0, SeekOrigin.Begin);
        byte[] bytes = brMyfile.ReadBytes(Convert.ToInt32(fsMyfile.Length.ToString()));
        // 关闭以上new的各个对象
        brMyfile.Close();
        return bytes;
    }
