Cursor Members
Cursor Class Methods Properties See Also Send Feedback

The Cursor type exposes the following members.

# Methods

| Name | Description
--- | --- | ---
| Add | Stores the key/data pair in the database.

Close

Discard the cursor. If you do not close the cursor before closing the database handle or the transaction handle that owns this cursor, then, closing either a database or transaction handle closes this 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.

(Inherited from BaseCursor.)

| Compare | Compare this cursor's position to another's. (Inherited from BaseCursor.)
| Count | Returns a count of the number of data items for the key to which the cursor refers. (Inherited from BaseCursor.)
| Delete | Delete the key/data pair to which the cursor refers.
| Dispose | Release the resources held by this object, and close the cursor if it is still open. (Inherited from BaseCursor.)
| Duplicate | Create a new cursor that uses the same transaction and locker ID as the original cursor.
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
| GetEnumerator | Returns an enumerator that iterates through the Cursor.
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.)
| GetType | Gets the Type of the current instance. (Inherited from Object.)
| Move | Overloaded.
| MoveFirst | Overloaded.
| MoveFirstMultiple | Overloaded. If positioning the cursor fails, CurrentMultiple contains an empty KeyValuePair<(Of <(TKey, TValue>)>).
| MoveFirstMultipleKey | Overloaded.
| MoveLast | Overloaded.
| MoveMultiple | Overloaded.
| MoveMultipleKey | Overloaded.
| MoveNext | Overloaded.
| MoveNextDuplicate | Overloaded.
| MoveNextDuplicateMultiple | Overloaded.
| MoveNextDuplicateMultipleKey | Overloaded.
| MoveNextMultiple | Overloaded.
| MoveNextMultipleKey | Overloaded.
| MoveNextUnique | Overloaded.
| MoveNextUniqueMultiple | Overloaded.
| MoveNextUniqueMultipleKey | Overloaded.
| MovePrev | Overloaded.
| MovePrevDuplicate | Overloaded.
| MovePrevUnique | Overloaded.
