// Construct a new, privately used culture that extends the en-US culture
// provided by the .NET Framework. In this sample, the CultureAndRegion-
// Types.Specific parameter creates a minimal CultureAndRegionInfoBuilder
// object that you must populate with culture and region information.

    CultureAndRegionInfoBuilder cib1 = null;
    CultureAndRegionInfoBuilder cib2 = null;
    try {
        cib1 = new CultureAndRegionInfoBuilder(

        }
    catch (ArgumentException ae)
        {
        Console.WriteLine(ae);
        return;
        }

// Populate the new CultureAndRegionInfoBuilder object with culture information.
    CultureInfo ci = new CultureInfo("en-US");
    cib1.LoadDataFromCultureInfo(ci);

// Populate the new CultureAndRegionInfoBuilder object with region information.
    RegionInfo  ri = new RegionInfo("US");
    cib1.LoadDataFromRegionInfo(ri);

// Display a property of the new custom culture.
    Console.Clear();
    Console.WriteLine(msg1, cib1.CultureName);

// Save the new CultureAndRegionInfoBuilder object in the specified file in
// LDML format. The file is saved in the same directory as the application
// that calls the Save method.

    Console.WriteLine("Saving the custom culture to a file...");
    try {
        cib1.Save( savedCARIB );
        }
    catch (IOException exc)
        {
        Console.WriteLine("** I/O exception: {0}", exc.Message);
        return;
        }

// Create a new CultureAndRegionInfoBuilder object from the persisted file.
    Console.WriteLine(msg2, savedCARIB);
    try {
        cib2 = CultureAndRegionInfoBuilder.CreateFromLdml( savedCARIB );
        }
    catch (XmlException xe)
        {
        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
// custom culture available to other applications. The mySavedCARIB.xml file
// remains on your computer.
    }
}

/*
This code example produces the following results:

The name of the original CultureAndRegionInfoBuilder is "x-en-US-sample".
Saving the custom culture to a file...
Reconstituting the CultureAndRegionInfoBuilder object from "mySavedCARIB.xml".
The name of the reconstituted CultureAndRegionInfoBuilder is "x-en-US-sample".

Remarks

The xmlFileName parameter specifies a file name that contains the XML representation of a CultureAndRegionInfoBuilder object. The format of the XML file is called Locale Data Markup Language (LDML) version 1.1. A new CultureAndRegionInfoBuilder object is created and initialized with the data in xmlFileName. The Save method performs the reverse operation of the CreateFromLdml method.

In the LDML file, the properties of a culture are specified as child elements of the <special> element in the <identity> section. A property value is typically specified by the element's type attribute. For example, the following excerpt from an LDML file defines a culture's parent as the English neutral culture.

XML

<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>

For more information about the LDML standard, see Unicode Technical Standard #35, "Locale Data Markup Language (LDML)" on the Unicode Consortium website.
