C# Modbus CRC校验

Modbus CRC校验，直接输入byte[]，输出bool

        public static bool CRC_Check(byte[] byteData)
        {
            bool Flag = false;
            byte[] CRC = new byte[2];

            UInt16 wCrc = 0xFFFF;
            for (int i = 0; i < byteData.Length-2; i++)
            {
                wCrc ^= Convert.ToUInt16(byteData[i]);
                for (int j = 0; j < 8; j++)
                {
                    if ((wCrc & 0x0001) == 1)
                    {
                        wCrc >>= 1;
                        wCrc ^= 0xA001;
                    }
                    else
                    {
                        wCrc >>= 1;
                    }
                }
            }

            CRC[1] = (byte)((wCrc & 0xFF00) >> 8);
            CRC[0] = (byte)(wCrc & 0x00FF);      
            if (CRC[1] == byteData[byteData.Length - 1]
                && CRC[0] == byteData[byteData.Length - 2])
            {
                Flag = true;
            }
            return Flag;
        }

调用

            byte[] Hex = new byte[8] { 0x01, 0x03, 0x00, 0x2A, 0x00, 0x02, 0xE5, 0xC3 };
            if (CRC_Check(Hex))
            {
                //你的代码
            }
