帮忙下面的代码反应成C#代码，谢谢各位

  unsigned short CRC16_CCITT(unsigned char * pData, unsigned int len)
    {
        unsigned int i;
        unsigned short crc = 0xc78c;

        unsigned int dd = *pData;
        for (i = 0; i < len; i++) 
        {
            dd = *pData++;
            crc = (crc << 8) ^ (unsigned short)CRCTab[(crc >> 8) ^ dd];
        }

        return crc;
    }

ushort[] CRCTab = null;//定义你没贴，略
ushort CRC16_CCITT(byte[] pData, uint len)
{
    ushort crc = 0xc78c;
    for (int i = 0; i < len; i++)
    {
        ushort dd = pData[i];
        crc = (ushort)((crc << 8) ^ (ushort)CRCTab[(crc >> 8) ^ dd]);
    }

    return crc;
}
