RegionInfo.ThreeLetterISORegionName Property
Gets the three-letter code defined in ISO 3166 for the country/region.
Namespace: System.Globalization
Assembly: mscorlib (in mscorlib.dll)
The ThreeLetterISORegionName property contains the three-letter code defined in ISO 3166 for this country/region. For example, the three-letter code for United States is "USA".
Case is not significant. However, the Name, the TwoLetterISORegionName, and the ThreeLetterISORegionName properties return the appropriate code in uppercase.
The following code example displays the properties of the RegionInfo class.
using System; using System.Globalization; public class SamplesRegionInfo { public static void Main() { // Displays the property values of the RegionInfo for "US". RegionInfo myRI1 = new 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 ); Console.WriteLine( " ThreeLetterISORegionName: {0}", myRI1.ThreeLetterISORegionName ); Console.WriteLine( " ThreeLetterWindowsRegionName: {0}", myRI1.ThreeLetterWindowsRegionName ); Console.WriteLine( " TwoLetterISORegionName: {0}", myRI1.TwoLetterISORegionName ); Console.WriteLine( " CurrencySymbol: {0}", myRI1.CurrencySymbol ); Console.WriteLine( " ISOCurrencySymbol: {0}", myRI1.ISOCurrencySymbol ); } } /* This code produces the following output. Name: US DisplayName: United States EnglishName: United States IsMetric: False ThreeLetterISORegionName: USA ThreeLetterWindowsRegionName: USA TwoLetterISORegionName: US CurrencySymbol: $ ISOCurrencySymbol: USD */
