this byte[] data,
int startIndex,
int length
)
GSF.IO.Checksums.ChecksumExtensions.CrcCCITTChecksum = function(data, startIndex, length);
View SourceParameters
- data Byte
- Data buffer to perform check-sum on.
- startIndex Int32
- Starts index in data buffer to begin check-sum.
- length Int32
- Total number of bytes from startIndex to
perform check-sum over.
Return Value
UInt16Computed CRC-CCITT checksum over the specified portion of the buffer.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
Byte. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).

The CRC-CCITT is a table based 16-bit CRC popular for modem protocols defined for use by the
Consultative Committee on International Telegraphy and Telephony (CCITT)
