Poznámky

LocalizationExtenderProvider může rozšířit o IRootDesigner sadu vlastností a metod, které poskytují podporu pro architekturu lokalizace rozhraní .NET Framework. Další informace o používání prostředků najdete v tématu Lokalizace.

Architektura podpory lokalizace umožňuje návrhářům inicializovat vlastnosti komponent pomocí souborů prostředků, které lze za běhu prohodit pro podporu různých jazyků, stylů specifických pro jazykovou verzi a dynamicky konfigurovatelných funkcí. Pomocí metod této třídy můžete povolit návrhářům a kódu generující serializátory načítání z prostředků a sestavení inicializační kód, který používá lokalizační funkce.

Výchozí serializátory, které se dodávají se sadou Visual Studio, jsou již schopné lokalizovat komponenty a ovládací prvky, ale pouze pokud vyhledá podporu pro architekturu lokalizace rozhraní .NET Framework. Chcete-li zjistit přítomnost lokalizační podpory, serializační systém musí najít veřejnou Boolean vlastnost s názvem "Lokalizovatelné" v kořenové komponentě návrháře. Pokud serializátor najde tuto vlastnost, vyhledá vlastnost typu CultureInfo s názvem "Language" k určení aktuální konfigurace prostředku. Výchozí serializátory používají tyto vlastnosti k určení, zda má lokalizovat jakékoli lokalizovatelné prostředky komponenty, a pokud ano, v jakém CultureInfo formátu by měly být informace o prostředcích uloženy.
