DataTableMapping Constructor (String, String, DataColumnMapping[])

Initializes a new instance of the DataTableMapping class when given a source table name, a DataTable name, and an array of DataColumnMapping objects.

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

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


Type: System.String
The case-sensitive source table name from a data source.
Type: System.String
The table name from a DataSet to map to.
Type: System.Data.Common.DataColumnMapping[]
An array of DataColumnMapping objects.

The following example creates a DataTableMapping object, sets some of its properties, and copies its ColumnMappings to an array. This example assumes that a DataColumnMappingCollection has been created.

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);
