What is the primary purpose of a data reader in ADO.NET?
- To establish a connection to the database
- To execute stored procedures
- To read and process data from a data source sequentially
- To update data in the database
A data reader in ADO.NET is primarily used to sequentially read and process data from a data source. It provides a forward-only, read-only stream of data from a database, allowing efficient retrieval of large datasets without storing the entire result set in memory. This makes it suitable for scenarios where fast, lightweight data access is required, such as data retrieval operations in web applications or data processing tasks.
