Namespace: System.Diagnostics
Assembly: System (in system.dll)
Syntax
'Declaration
Public ReadOnly Property Verbs As String()
'Usage
Dim instance As ProcessStartInfo
Dim value As String()
value = instance.Verbs
public string[] Verbs { get; }
public:
property array<String^>^ Verbs {
array<String^>^ get ();
}
/** @property */
public String[] get_Verbs ()
public function get Verbs () : String[]
Eigenschaftenwert
Die Aktionen, die das System auf die durch die FileName-Eigenschaft angegebene Datei anwenden kann.
Hinweise
Wenn Sie die Verbs-Eigenschaft verwenden, müssen Sie beim Festlegen des Werts der FileName-Eigenschaft die Dateinamenerweiterung einschließen. Durch die Dateinamenerweiterung wird die Gruppe möglicher Verben bestimmt.
Beispiel
Im Beispiel werden die definierten Aktionen für den Eingabedateinamen angezeigt. Wenn der Benutzer eine der definierten Aktionen auswählt, wird im Beispiel ein neuer Prozess mit der ausgewählten Aktion und dem Eingabedateinamen gestartet.
