The BTreeCursor type exposes the following members.

Methods

  NameDescription
AddOverloaded.
AddUnique
Insert the specified key/data pair into the database, unless a key/data pair comparing equally to it already exists in the database.
Close

Discard the cursor.

It is possible for the Close() method to throw a DeadlockException, signaling that any enclosing transaction should be aborted. If the application is already intending to abort the transaction, this error should be ignored, and the application should proceed.

After Close has been called, regardless of its result, the object may not be used again.
