If the cursor is not yet initialized, MoveNextUnique is identical to MoveFirst(LockingInfo). Otherwise, move the cursor to the next non-duplicate key in the database, and store that key and associated datum in Current. MoveNextUnique will return false if no non-duplicate key/data pairs exist after the cursor position in the database.

Namespace:  BerkeleyDB
Assembly:  libdb_dotnet52 (in libdb_dotnet52.dll) Version:


public bool MoveNextUnique(
	LockingInfo info

Type: BerkeleyDB..::.LockingInfo
The locking behavior to use.

Return Value

True if the cursor was positioned successfully, false otherwise.


If the database is a Queue or Recno database, MoveNextUnique will ignore any keys that exist but were never explicitly created by the application, or those that were created and later deleted.

If positioning the cursor fails, Current will contain an empty KeyValuePair<(Of <(TKey, TValue>)>).
