Contains a collection of DataColumnMapping objects, and is implemented by the System.Data.Common.DataColumnMappingCollection, which is used in common by .NET Framework data providers.

The System.Data.IColumnMappingCollection interface enables an inheriting class to implement a ColumnMapping collection. For more information, see [<topic://cpconsettingupdatatabledatacolumnmappings>].
Classes that inherit System.Data.IColumnMappingCollection must implement all inherited members, and typically define additional members to add provider-specific functionality. For example, the System.Data.IColumnMappingCollection interface defines the IColumnMappingCollection.RemoveAt(string) method. In turn, the System.Data.Common.DataTableMappingCollection class inherits this method, and defines two additional overloads of System.Data.Common.DataTableMappingCollection.RemoveAt(int).
