NumberFormatInfo.CurrentInfo Eigenschap
Definitie
Belangrijk
Bepaalde informatie heeft betrekking op een voorlopige productversie die aanzienlijk kan worden gewijzigd voordat deze wordt uitgebracht. Microsoft biedt geen enkele expliciete of impliciete garanties met betrekking tot de informatie die hier wordt verstrekt.
Hiermee haalt u een alleen-lezen op NumberFormatInfo waarmee waarden worden opgemaakt op basis van de huidige cultuur.
public:
static property System::Globalization::NumberFormatInfo ^ CurrentInfo { System::Globalization::NumberFormatInfo ^ get(); };public static System.Globalization.NumberFormatInfo CurrentInfo { get; }static member CurrentInfo : System.Globalization.NumberFormatInfoPublic Shared ReadOnly Property CurrentInfo As NumberFormatInfoWaarde van eigenschap
Een alleen-lezen NumberFormatInfo op basis van de cultuur van de huidige thread.
Voorbeelden
In het volgende voorbeeld ziet u dat de objecten die worden geretourneerd door de CurrentInfo en CultureInfo.CurrentCulture.NumberFormat eigenschappen identiek zijn. Vervolgens wordt weerspiegeling gebruikt om de eigenschapswaarden weer te geven van het NumberFormatInfo object dat wordt geretourneerd door de eigenschap op een systeem waarvan de CurrentInfo huidige cultuur is en-US.

Opmerkingen
Het ophalen van een NumberFormatInfo object uit de CurrentInfo eigenschap is gelijk aan het ophalen van een NumberFormatInfo object uit de CultureInfo.CurrentCulture.NumberFormat eigenschap.
