        Console.WriteLine("** XML validation exception: {0}", xe.Message);
        return;
        }

// Display a property of the resonstituted custom culture.
    Console.WriteLine(msg3, cib2.CultureName);

// At this point you could call the Register method and make the reconstituted

Commenti

Il xmlFileName parametro specifica un nome di file che contiene la rappresentazione XML di un CultureAndRegionInfoBuilder oggetto . Il formato del file XML è denominato Locale Data Markup Language (LDML) versione 1.1. Viene creato e inizializzato un nuovo CultureAndRegionInfoBuilder oggetto con i dati in xmlFileName. Il Save metodo esegue l'operazione inversa del CreateFromLdml metodo .

Nel file LDML le proprietà di impostazioni cultura vengono specificate come elementi figlio dell'elemento <special> nella <identity> sezione . Un valore della proprietà viene in genere specificato dall'attributo dell'elemento type . Ad esempio, l'estratto seguente da un file LDML definisce l'elemento padre di una cultura come impostazioni cultura indipendenti dall'inglese.

<identity>
   <version number="1.1">ldml version 1.1</version>
   <generation date="2012-05-16" />
   <special xmlns:msLocale="http://schemas.microsoft.com/globalization/2004/08/carib/ldml">
      <!-content removed -->
      <msLocale:parentName type="en" />
      <!-content removed -->
   </special>
</identity>
