member this.GetNeverSupportedPatterns : unit -> System.Windows.Automation.AutomationPattern[]

Public Function GetNeverSupportedPatterns () As AutomationPattern()

Gibt zurück

AutomationPattern[]

Ein Array von Benutzeroberflächenautomatisierung Musterbezeichnern.

Beispiele

Im folgenden Beispiel werden GetNeverSupportedPatterns alle Arten von ControlType Elementen aufgerufen, die als statisches Feld in der ControlType Klasse enthalten sind.

/// Control types are obtained by reflection.

Hinweise

Diese Methode ist nützlich für Benutzeroberflächenautomatisierung Clients wie Testframeworks für eine Anbieterimplementierung, die alle Steuerelementmuster finden muss, die für diesen Steuerelementtyp nicht zulässig sind.
