Définition
Important
Certaines informations portent sur la préversion du produit qui est susceptible d’être en grande partie modifiée avant sa publication. Microsoft exclut toute garantie, expresse ou implicite, concernant les informations fournies ici.
Obtient un objet NumberFormatInfo en lecture seule qui met en forme des valeurs en fonction de la culture actuelle.
public:
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 NumberFormatInfoValeur de propriété
Objet NumberFormatInfo en lecture seule basé sur la culture du thread actif.
Exemples
L’exemple suivant montre que les objets retournés par les CurrentInfo CultureInfo.CurrentCulture.NumberFormat Propriétés et sont identiques. Il utilise ensuite la réflexion pour afficher les valeurs de propriété de l' NumberFormatInfo objet retourné par la CurrentInfo propriété sur un système dont la culture actuelle est en-US.

Remarques
La récupération d’un NumberFormatInfo objet à partir de la CurrentInfo propriété est équivalente à NumberFormatInfo la récupération d’un objet de la CultureInfo.CurrentCulture.NumberFormat propriété.
