DocumentPageView.Dispose Method

Releases all resources used by the DocumentPageView.

Namespace:  System.Windows.Controls.Primitives
Assembly:  PresentationFramework (in PresentationFramework.dll)

protected void Dispose()

Call Dispose after finished using each DocumentPageView instance. After Dispose is called, the DocumentPageView is released for garbage collection and should no longer be referenced by the application. After calling Dispose and being released, the garbage collector can reclaim the DocumentPageView memory and resources. For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method.


Always call Dispose as the final call to release each DocumentPageView instance. If Dispose is not called, the resources the DocumentPageView is using will not be freed until the garbage collector later calls the page viewer's Finalize method.
