DbDataReader.Dispose Method

Definition

Namespace:

System.Data.Common

Assembly:

System.Data.Common.dll

Releases the resources used by the DbDataReader and calls Close().

Overloads

Dispose()	Releases all resources used by the current instance of the DbDataReader class.
Dispose(Boolean)	Releases the unmanaged resources used by the DbDataReader and optionally releases the managed resources.

Dispose()

Source:

DbDataReader.cs

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

public:
 virtual void Dispose();

public void Dispose ();

abstract member Dispose : unit -> unit
override this.Dispose : unit -> unit

Public Sub Dispose ()

Implements

Dispose()

Remarks

Call Dispose or DisposeAsync when you've finished using the DbDataReader. Calling one of these methods leaves the DbDataReader in an unusable state. After disposing, 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.

Note

Always 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.
