Solution 1

You can't. The documentation[^] states that it's forward-only;

"Provides a way of reading a forward-only stream of data rows from a data source."

Your best alternative is to close the reader and open a new one.

Solution 2

As has been mentioned a DataReader is forward only, if you need to loop through the same data multiple times you should look at loading the data into a DataSet via a DataAdapter.
