Namespace:   System.Data.Common
Assembly:  System.Data (in System.Data.dll)

public DataTableMapping(
	string sourceTable,
	string dataSetTable,
	DataColumnMapping[] columnMappings
)

Parameters

sourceTable
Type: System.String

The case-sensitive source table name from a data source.

columnMappings

public void CreateDataTableMapping() 
{
    // ...
    // create mappings
    // ...

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

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