DbDataReader.Dispose Method

Releases all resources used by the current instance of the DbDataReader class.

Namespace:  System.Data.Common
Assembly:  System.Data (in System.Data.dll)

'Declaration
Public Sub Dispose

Implements

IDisposable.Dispose

Call Dispose when you are finished using the DbDataReader. The Dispose method leaves the DbDataReader in an unusable state. After calling Dispose, you must release all references to the DbDataReader so the garbage collector can reclaim the memory that the DbDataReader was occupying.

For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method.

NoteNote

Always call Dispose before you release your last reference to the DbDataReader. Otherwise, the resources it is using will not be freed until the garbage collector calls the DbDataReader object's Finalize method.
