Examples

The following example exports the collection to an array of DataColumnMapping objects. It then clears the collection, and returns true if the parameters are no longer persisting. This example assumes that a DataColumnMappingCollection collection has been created.

public bool PushIntoArray()
{
    // ...
    // create mappings
    // ...
    DataColumnMapping[] columns = new DataColumnMapping[0];
    mappings.CopyTo(columns, 0);
    mappings.Clear();
    return true;
}
