	CurrencySymbol	Gets the currency symbol associated with the country/region.
	CurrentRegion	Gets the RegionInfo that represents the country/region used by the current thread.
	DisplayName	Gets the full name of the country/region in the language of the localized version of the .NET Framework for Silverlight.
	EnglishName	Gets the full name of the country/region in English.
	IsMetric	Gets a value indicating whether the country/region uses the metric system for measurements.
	ISOCurrencySymbol	Gets the three-character ISO 4217 currency symbol associated with the country/region.
	Name	Gets the name or ISO 3166 two-letter country/region code for the current RegionInfo object.
	NativeName	Gets the name of a country/region formatted in the native language of the country/region.
	TwoLetterISORegionName	Gets the two-letter code defined in ISO 3166 for the country/region.

Methods

	Name	Description
	Equals	Determines whether the specified object is the same as the current RegionInfo object. (Overrides Object.Equals(Object).)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for the current RegionInfo, suitable for hashing algorithms and data structures, such as a hash table. (Overrides Object.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string containing the culture name or ISO 3166 two-letter country/region code specified for the current RegionInfo. (Overrides Object.ToString().)

Remarks

In contrast to CultureInfo, RegionInfo does not represent user preferences and does not depend on the user's language or culture.

The RegionInfo name is one of the two-letter codes defined in ISO 3166 for a country/region. Case is not significant. The Name and TwoLetterISORegionName properties retrieve the appropriate codes in uppercase.

Note:
Although a RegionInfo object is identified by a two-letter country/region code, that two-letter code cannot be used to instantiate a new RegionInfo object. Instead, to instantiate a new RegionInfo object, a full culture name must be passed to its class constructor. A full culture name combines a language code with a country or region code, such as "en-US", "zh-Hans", and "eu-ES".

The following is a list of the predefined RegionInfo names that are recognized by this class and other classes in the System.Globalization namespace.
