Remarks

Diese Methode ist eine bequeme Methode zum Aufrufen RegisterName.This method is a convenience method for calling RegisterName. Die Implementierung überprüft aufeinanderfolgenden, übergeordneten Elementen, bis die entsprechende NameScope -Implementierung, die gefunden wird, suchen Sie ein Element, das implementiert INameScope.The implementation will check successive parent elements until it finds the applicable NameScope implementation, which is found by finding an element that implements INameScope. Weitere Informationen zu Namescopes finden Sie unter WPF-XAML-Namescopes.For more information about namescopes, see WPF XAML Namescopes.

Aufrufen von RegisterName ist erforderlich, um ordnungsgemäß einbinden Animationsstoryboards für Anwendungen, wenn im Code erstellt.Calling RegisterName is necessary in order to correctly hook up animation storyboards for applications when created in code. Dies ist, da einer der Schlüsselwerte storyboard-Eigenschaften, TargetName, eine Laufzeit-Suche verwendet, statt einen Verweis auf ein Target-Element zu nutzen.This is because one of the key storyboard properties, TargetName, uses a run-time name lookup instead of being able to take a reference to a target element. Dies gilt auch, wenn dieses Element durch einen Verweis aus dem Code zugegriffen werden.This is true even if that element is accessible by reference from the code. Weitere Informationen darüber, warum zum Registrieren von Namen für die Storyboard-Zielen müssen finden Sie unter Übersicht über Storyboards.For more information on why you need to register names for storyboard targets, see Storyboards Overview.
