DataSet.CreateDataReader Method (DataTable[])

Returns a DataTableReader with one result set per DataTable.

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

public function CreateDataReader(
	... dataTables : DataTable[]
) : DataTableReader

Parameters

dataTables
Type: System.Data.DataTable[]

An array of DataTables providing the order of the result sets to be returned in the DataTableReader.

Return Value

Type: System.Data.DataTableReader
A DataTableReader containing one or more result sets, corresponding to the DataTable instances contained within the source DataSet. The returned result sets are in the order specified by the dataTables parameter.

In order to ensure that the order of the result sets within the returned DataTableReader, if a DataTable within the DataSet is empty, it is represented by an empty result set within the returned DataTableReader. Because this overloaded version allows you to supply a list of DataTable instances as parameters, you can specify the order in which the result sets appear within the returned DataTableReader.

This example, a Console application, creates three DataTable instances and adds each to a DataSet. The example calls the CreateDataReader method and displays the contents of the returned DataTableReader. Note that the order of the result sets in the DataTableReader is controlled by the order of the DataTable instances passed as parameters. The example displays the results in the Console window.
