DataSet::CreateDataReader Method

Returns a DataTableReader with one result set per DataTable, in the same sequence as the tables appear in the Tables collection.

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

public:
DataTableReader^ CreateDataReader()

Return Value

Type: System.Data::DataTableReader
A DataTableReader containing one or more result sets, corresponding to the DataTable instances contained within the source DataSet.

In order to ensure 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.

The following example creates three DataTable instances, and adds each to a DataSet. The example then passes the filled DataSet to a procedure that calls the CreateDataReader method, and proceeds to iterate through all the result sets contained within the DataTableReader. The example displays the results in the Console window.
