Ejemplos

En el ejemplo de código siguiente se muestra que CultureInfo. Clone también clona las instancias de DateTimeFormatInfo y NumberFormatInfo asociadas a la CultureInfo.The following code example shows that CultureInfo.Clone also clones the DateTimeFormatInfo and NumberFormatInfo instances associated with the CultureInfo.

using namespace System;
using namespace System::Globalization;
int main()
{
   
   // Creates and initializes a CultureInfo.
   CultureInfo^ myCI = gcnew CultureInfo( "en-US",false );
   
   // Clones myCI and modifies the DTFI and NFI instances associated with the clone.
   CultureInfo^ myCIclone = dynamic_cast<CultureInfo^>(myCI->Clone());
   myCIclone->DateTimeFormat->AMDesignator = "a.m.";
   myCIclone->DateTimeFormat->DateSeparator = "-";
   myCIclone->NumberFormat->CurrencySymbol = "USD";
   myCIclone->NumberFormat->NumberDecimalDigits = 4;
   
   // Displays the properties of the DTFI and NFI instances associated with the original and with the clone. 
   Console::WriteLine( "DTFI/NFI PROPERTY\tORIGINAL\tMODIFIED CLONE" );
   Console::WriteLine( "DTFI.AMDesignator\t{0}\t\t{1}", myCI->DateTimeFormat->AMDesignator, myCIclone->DateTimeFormat->AMDesignator );
   Console::WriteLine( "DTFI.DateSeparator\t{0}\t\t{1}", myCI->DateTimeFormat->DateSeparator, myCIclone->DateTimeFormat->DateSeparator );
   Console::WriteLine( "NFI.CurrencySymbol\t{0}\t\t{1}", myCI->NumberFormat->CurrencySymbol, myCIclone->NumberFormat->CurrencySymbol );
   Console::WriteLine( "NFI.NumberDecimalDigits\t{0}\t\t{1}", myCI->NumberFormat->NumberDecimalDigits, myCIclone->NumberFormat->NumberDecimalDigits );
}

OverridesOverrides

El usuario puede optar por invalidar algunos de los valores asociados a la referencia cultural actual de Windows a través de la parte de opciones de idioma y configuración regional del panel de control.The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. Por ejemplo, el usuario podría elegir mostrar la fecha en un formato diferente o utilizar una moneda distinta de la predeterminada para la referencia cultural.For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture.

Si UseUserOverride se true y la referencia cultural especificada coincide con la referencia cultural actual de Windows, el CultureInfo utiliza esas invalidaciones, incluida la configuración de usuario para las propiedades de la instancia de DateTimeFormatInfo devuelta por la propiedad DateTimeFormat y las propiedades de la NumberFormatInfo instancia de devuelta por la propiedad NumberFormat.If UseUserOverride is true and the specified culture matches the current culture of Windows, the CultureInfo uses those overrides, including user settings for the properties of the DateTimeFormatInfo instance returned by the DateTimeFormat property, and the properties of the NumberFormatInfo instance returned by the NumberFormat property. Si la configuración del usuario es incompatible con la referencia cultural asociada al CultureInfo, por ejemplo, si el calendario seleccionado no es ninguno de los OptionalCalendars, los resultados de los métodos y los valores de las propiedades son indefinidos.If the user settings are incompatible with the culture associated with the CultureInfo, for example, if the selected calendar is not one of the OptionalCalendars, the results of the methods and the values of the properties are undefined.

Los valores de las propiedades DateTimeFormat y NumberFormat no se calculan hasta que el usuario obtiene acceso a la propiedad.The values of the DateTimeFormat property and the NumberFormat property are not calculated until the user accesses the property. Si el usuario usa el panel de control para cambiar la referencia cultural actual a una nueva referencia cultural mientras la aplicación se está ejecutando y, a continuación, accede a la propiedad DateTimeFormat o NumberFormat, la aplicación recupera los valores predeterminados de la nueva referencia cultural.If the user uses the Control Panel to change the current culture to a new culture while the application is running and then accesses the DateTimeFormat or NumberFormat property, the application retrieves the defaults for the new culture. no las invalidaciones de la referencia cultural original.not the overrides for the original culture. Para conservar las invalidaciones de la referencia cultural actual original, la aplicación debe tener acceso a las propiedades DateTimeFormat y NumberFormat antes de cambiar la referencia cultural actual.To preserve the overrides for the original current culture, the application should access the DateTimeFormat and NumberFormat properties before changing the current culture.
