一段c语言代码转换为c#代码

[萌新级程序猿]

uint16_t crc_sum(uint8_t* msg, uint8_t length)
        {
            uint8_t i;
            uint16_t crc;

            crc = 0xFFFF;
            for (i = 0; i < length; i++)
            {
                crc = crc_polynomial(msg[i], crc);
            }

            return crc;
        }
      

        uint16_t crc_polynomial(uint8_t b, uint16_t acc)
        {
            acc = (uint8_t)(acc >> 8) | (acc << 8);
            acc ^= b;
            acc ^= (uint8_t)(acc & 0xff) >> 4;
            acc ^= (acc << 8) << 4;
            acc ^= ((acc & 0xff) << 4) << 1;

            return acc;
        }
