Use the Locale property of the SPWeb class to return the LCID of a subsite's locale. Otherwise, use the Locales property of the SPRegionalSettings class to return an SPLocaleCollection object that represents the collection of locales for the subsite. Use an indexer to return a single locale from the collection. For example, if the collection is assigned to a variable named myLocales, use myLocales[index] in Microsoft Visual C#, or myLocales(index) in Microsoft Visual Basic, where index is the index number of the locale in the collection.
