    )

Visual Basic (Declaration)

    	DatabaseEntry^ data,
    	Transaction^ txn,
    	LockingInfo^ info
    )

#### Parameters

key
  Type: BerkeleyDB..::.DatabaseEntry
  The key to search for

data
  Type: BerkeleyDB..::.DatabaseEntry
  The data to search for

txn
  Type: BerkeleyDB..::.Transaction
  txn is a Transaction object returned from BeginTransaction()()(); if the operation is part of a Berkeley DB Concurrent Data Store group, txn is a handle returned from BeginCDSGroup()()(); otherwise null.

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

#### Return Value

A KeyValuePair<(Of <(TKey, TValue>)>) whose Key parameter is key and whose Value parameter is data.

If txn is null and the operation occurs in a transactional database, the operation will be implicitly transaction protected.

# Exceptions

Exception | Condition
--- | ---
BerkeleyDB..::.NotFoundException | A NotFoundException is thrown if key and data are not in the database.
BerkeleyDB..::.KeyEmptyException | A KeyEmptyException is thrown if the database is a QueueDatabase or RecnoDatabase database and key exists, but was never explicitly created by the application or was later deleted.
