This class contains a collection of DataColumnMapping objects and is typically used for the DataTableMapping.ColumnMappings property. You can look up an individual DataColumnMapping by index or data source column name using the indexer. You can also use the GetByDataSetColumn( ) to retrieve a DataColumnMapping using the System.Data.DataSet name.
