NumberFormatInfo.CurrentInfo Propriété

Définition

Obtient un objet NumberFormatInfo en lecture seule qui met en forme des valeurs en fonction de la culture actuelle.Gets a read-only NumberFormatInfo that formats values based on the current culture.

public:
 static property System::Globalization::NumberFormatInfo ^ CurrentInfo { System::Globalization::NumberFormatInfo ^ get(); };
public static System.Globalization.NumberFormatInfo CurrentInfo { get; }
member this.CurrentInfo : System.Globalization.NumberFormatInfo
Public Shared ReadOnly Property CurrentInfo As NumberFormatInfo

Valeur de propriété

Objet NumberFormatInfo en lecture seule basé sur la culture du thread actif.A read-only NumberFormatInfo based on the culture of the current thread.

Exemples

L’exemple suivant montre que les objets retournés CurrentInfo par CultureInfo.CurrentCulture.NumberFormat les propriétés et sont identiques.The following example shows that the objects returned by the CurrentInfo and CultureInfo.CurrentCulture.NumberFormat properties are identical. Il utilise ensuite la réflexion pour afficher les valeurs de propriété NumberFormatInfo de l’objet retourné CurrentInfo par la propriété sur un système dont la culture actuelle est en-US.It then uses reflection to display the property values of the NumberFormatInfo object returned by the CurrentInfo property on a system whose current culture is en-US.

Remarques

La récupération d' NumberFormatInfo un objet à CurrentInfo partir de la propriété est équivalente NumberFormatInfo à la récupération CultureInfo.CurrentCulture.NumberFormat d’un objet de la propriété.Retrieving a NumberFormatInfo object from the CurrentInfo property is equivalent to retrieving a NumberFormatInfo object from the CultureInfo.CurrentCulture.NumberFormat property.
