NumberFormatInfo.CurrentInfo Propiedad

Definición

Espacio de nombres:

System.Globalization

Ensamblado:

System.Runtime.dll

Source:

NumberFormatInfo.cs

Obtiene un NumberFormatInfo de solo lectura que aplica formato a los valores basándose en la referencia cultural actual.

public:
 static property System::Globalization::NumberFormatInfo ^ CurrentInfo { System::Globalization::NumberFormatInfo ^ get(); };

public static System.Globalization.NumberFormatInfo CurrentInfo { get; }

static member CurrentInfo : System.Globalization.NumberFormatInfo

Public Shared ReadOnly Property CurrentInfo As NumberFormatInfo

Valor de propiedad

NumberFormatInfo

NumberFormatInfo de solo lectura que se basa en la referencia cultural del subproceso actual.

Ejemplos

En el ejemplo siguiente se muestra que los objetos devueltos por las CurrentInfo propiedades y CultureInfo.CurrentCulture.NumberFormat son idénticos. A continuación, usa la reflexión para mostrar los valores de propiedad del NumberFormatInfo objeto devuelto por la CurrentInfo propiedad en un sistema cuya referencia cultural actual es en-US.
