NumberFormatInfo.CurrentInfo 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 eine schreibgeschützte NumberFormatInfo ab, die Werte auf Grundlage der aktuellen Kultur formatiert.

static property System::Globalization::NumberFormatInfo ^ CurrentInfo { System::Globalization::NumberFormatInfo ^ get(); };public static System.Globalization.NumberFormatInfo CurrentInfo { get; }member this.CurrentInfo : System.Globalization.NumberFormatInfoPublic Shared ReadOnly Property CurrentInfo As NumberFormatInfoEigenschaftswert
Eine schreibgeschützte NumberFormatInfo, die auf der Kultur des aktuellen Threads basiert.
Beispiele
Das folgende Beispiel zeigt, dass die von den Eigenschaften und CurrentInfo zurückgegebenen CultureInfo.CurrentCulture.NumberFormat Objekte identisch sind. Anschließend wird reflektion verwendet, um die Eigenschaftswerte des Objekts anzuzeigen, das von der -Eigenschaft auf einem System zurückgegeben wird, dessen aktuelle Kultur NumberFormatInfo CurrentInfo en-US ist.
