Beispiele

Im folgenden Codebeispiel wird einer Komponente ein LocalizationExtenderProvider hinzugefügt.

// Adds a LocalizationExtenderProvider that provides localization support properties to the specified component.
extender = gcnew LocalizationExtenderProvider( this->component->Site,this->component );

// Adds a LocalizationExtenderProvider that provides localization support properties to the specified component.
extender = new LocalizationExtenderProvider(this.component.Site, this.component);

' Adds a LocalizationExtenderProvider that provides localization support properties to the specified component.
extender = New LocalizationExtenderProvider(Me.component_.Site, Me.component_)

Das folgende Codebeispiel enthält eine Beispielkomponente und einen Designer. Der Designer verwendet ein LocalizationExtenderProvider , um die Lokalisierungsunterstützungseigenschaften für die Komponente hinzuzufügen.

Hinweise

LocalizationExtenderProviderkann eine IRootDesigner mit einer Reihe von Eigenschaften und Methoden erweitern, die Unterstützung für die .NET Framework Lokalisierungsarchitektur bieten. Weitere Informationen zur Verwendung von Ressourcen finden Sie unter Lokalisierung.

Die Lokalisierungsunterstützungsarchitektur ermöglicht Es Designern, Komponenteneigenschaften mithilfe von Ressourcendateien zu initialisieren, die zur Laufzeit ausgetauscht werden können, um eine Vielzahl von Sprachen, kulturspezifischen Stilen und dynamisch konfigurierbaren Features zu unterstützen. Sie können die Methoden dieser Klasse verwenden, um Designern und codegenerierenden Serialisierern das Laden aus Ressourcen zu ermöglichen und Initialisierungscode zu erstellen, der Lokalisierungsfeatures verwendet.

Die standardmäßigen Serialisierer, die in Visual Studio enthalten sind, sind bereits in der Lage, Komponenten und Steuerelemente zu lokalisieren, aber sie tun dies nur, wenn sie Unterstützung für die .NET Framework Lokalisierungsarchitektur finden. Um das Vorhandensein von Lokalisierungsunterstützung zu erkennen, muss das Serialisierungssystem eine öffentliche Boolean Eigenschaft namens "Localizable" für die Stamm-Designer-Komponente suchen. Wenn ein Serialisierer diese Eigenschaft findet, sucht es nach einer Eigenschaft vom Typ CultureInfo "Language", um die aktuelle Ressourcenkonfiguration zu bestimmen. Standardserialisierer verwenden diese Eigenschaften, um zu bestimmen, ob lokalisierbare Ressourcen der Komponente lokalisiert werden sollen und in welchem CultureInfo Format die Ressourceninformationen gespeichert werden sollen.
