int main()
{
   
   // Displays the property values of the RegionInfo for "US".
   RegionInfo^ myRI1 = gcnew RegionInfo( "US" );
   Console::WriteLine( "   Name:                         {0}", myRI1->Name );
   Console::WriteLine( "   DisplayName:                  {0}", myRI1->DisplayName );
   Console::WriteLine( "   EnglishName:                  {0}", myRI1->EnglishName );
   Console::WriteLine( "   IsMetric:                     {0}", myRI1->IsMetric );

Remarks

The RegionInfo name is one of the two-letter codes defined in ISO 3166 for country/region. For example, the two-letter code for United States is "US".

Important

In some cases, the TwoLetterISORegionName property may have more than two characters. For example, the value of the TwoLetterISORegionName property for the Caribbean region is "029".

Case is not significant. However, the Name, TwoLetterISORegionName, and ThreeLetterISORegionName properties return the appropriate code in uppercase.

Warning

If you want to persist a RegionInfo object or communicate it between processes, you should instantiate it by using a full culture name rather than a two-letter ISO region code. Because RegionInfo properties depend on script and language, instantiating a RegionInfo object by using only a region code loses context and data.

The predefined RegionInfo names are listed in ISO 3166: Country codes.
