Methods

	Name	Description
	CompareKeys	Compares two specified keys and returns an integer that indicates their relationship to one another in the sort order.
	ComparePartialKeys	Compares two specified partial keys and returns an integer that indicates their relationship to one another in the sort order.
	CompareTo	Compares this instance with a specified other GenSortRecord and returns an integer that indicates whether this instance precedes, follows, or appears in the same position in the sort order as the specified GenSortRecord.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	ExtractKey	Extracts the key from the record and converts it to a string.
	ExtractKeyBytes	Extract the key from the record and copies it to a new byte array.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Read	Reads the GenSortRecord from the specified reader.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Write	Writes the GenSortRecord to the specified writer.

Fields

	Name	Description
	KeySize	The size of the key of the record, in bytes.
	RecordSize	The size of each record, in bytes.

Remarks

Records for GraySort are 100 bytes in length, of which 10 bytes are the key and the remaining 90 bytes contain the record number and some filler data. Because the GenSortRecord class is only used for sorting, it makes no attempt to parse any of the data except the key.

The records can contain either ASCII data, or arbitrary binary data.
