ForEachVariableMapping.ValueIndex Eigenschaft
Definition
Wichtig
Einige Informationen beziehen sich auf Vorabversionen, die vor dem Release ggf. grundlegend überarbeitet werden. Microsoft übernimmt hinsichtlich der hier bereitgestellten Informationen keine Gewährleistungen, seien sie ausdrücklich oder konkludent.
Ruft den Index für Enumeratoren, die Auflistungen als Wert bereitstellen, in das Array ab oder legt ihn fest.
public:
property System::Object ^ ValueIndex { System::Object ^ get(); void set(System::Object ^ value); };
public object ValueIndex { get; set; }
member this.ValueIndex : obj with get, set
Public Property ValueIndex As Object
Eigenschaftswert
Ein Objekt, das den Index im Array darstellt.
