The DataReader class in ADO.NET is a forward-only, read-only data stream that enables rapid retrieval of data from a database without keeping the result set in memory. It provides a fast and efficient way to iterate through the rows returned by a query, as it eliminates the need to maintain an in-memory cache of all rows.
