    // ... 
    // create mappings 
    // ...

    DataColumnMapping[] columns1 = {};
    mappings.CopyTo(columns1, 0);
    DataTableMapping mapping =
        new DataTableMapping("Categories", "DataCategories", columns1);

    DataColumnMapping[] columns2 = {};
    mapping.ColumnMappings.CopyTo(columns2, 0);
