This method clears the contents of the collection.

Declaration

// C#
public void Clear();

Exceptions

InvalidOperationException - The bulk copy operation is in progress.

Remarks

The Clear method is most commonly used when an application uses a single OracleBulkCopy instance to process more than one bulk copy operation. If column mappings are created for one bulk copy operation, the OracleBulkCopyColumnMappingCollection must be cleared after the WriteToServer method invocation and before the next bulk copy is processed.

It is usually more efficient to perform several bulk copies using the same OracleBulkCopy instance than to use a separate OracleBulkCopy for each operation.
