Cursor..::.MoveNextDuplicate Method (DatabaseEntry, DatabaseEntry, LockingInfo)
Cursor Class See Also Send Feedback

If the next key/data pair of the database is a duplicate data record for the current key/data pair, move the cursor to the next key/data pair in the database, and store that pair in Current. MoveNextDuplicate will return false if the next key/data pair of the database is not a duplicate data record for the current key/data pair. If either the key or the data is partial DatabaseEntry, its PartialLen bytes starting PartialOffset bytes from the beginning of the retrieved data record are returned as if they comprised the entire record. If any or all of the specified bytes do not exist in the record, MoveNextDuplicate is successful, and any existing bytes are returned.
