The IDataReader interface enables you to implement a DataReader class, which provides a means of reading one or more forward-only streams of result sets. For more information about DataReader classes, see Implementing a DataReader Class for a Data Processing Extension.

An application does not create an instance of the IDataReader interface directly, but creates an instance of a class that implements IDataReader.

Classes that implement IDataReader must also implement the required members, and typically define additional members to add provider-specific functionality.

Changes made to a result set by another process or thread while data is being read may be visible to the user of a class that implements an IDataReader. However, the precise behavior is both provider and timing dependent.

Users do not create an instance of a DataReader class directly. Instead, they obtain the DataReader through the ExecuteReader method of the Command object. Therefore, you should mark DataReader constructors as internal.
