SqlDataReader marshal by reference, disposable

SqlDataReader marshal by reference, disposable

System.Data.SqlClient (system.data.dll) sealed class

This class represents a forward-only, read-only cursor that reads data from a SQL Server database and allows you to access it one record at a time. For information about the basic SqlDataReader methods and properties, refer to the reference for the System.Data.IDataReader and System.Data.IDataRecord interfaces, which SqlDataReader implements. In addition, you'll find that SqlDataReader adds many methods that retrieve data in native SQL Server data types.
