BTreeBaseKey, ValueGetKeyId Method (Key, Byte)

When Key type implements IOptimizedPersistable, you can use this function to get the Id of the persistent object instead of the entire object. Use for performance reasons in certain cases where reading the object isn't desired. To avoid opening the object, a comparison array which is flagged as complete key must be used.

public ulong GetKeyId(
	Key key,
	byte[] comparisonArray
)

Public Function GetKeyId ( 
	key As Key,
	comparisonArray As Byte()
) As ULong

public:
unsigned long long GetKeyId(
	Key key, 
	array<unsigned char>^ comparisonArray
)

member GetKeyId : 
        key : 'Key * 
        comparisonArray : byte[] -> uint64
