Constructors
ProviderBasedLocalizationService()
Initializes a new instance of the ProviderBasedLocalizationService class.
Declaration
public ProviderBasedLocalizationService()
ProviderBasedLocalizationService(ResourceKeyHandler)
Initializes a new instance of the ProviderBasedLocalizationService class.
Declaration
public ProviderBasedLocalizationService(ResourceKeyHandler keyHandler)
Parameters
Type | Name | Description |
---|---|---|
ResourceKeyHandler | keyHandler | The handler used to manipulate resource keys. |
Properties
AvailableLocalizations
Gets all available localizations that the LocalizationService has knowledge of.
Declaration
public override IEnumerable<CultureInfo> AvailableLocalizations { get; }
Property Value
Type | Description |
---|---|
System.Collections.Generic.IEnumerable<System.Globalization.CultureInfo> |
Overrides
Providers
Gets a list of providers that are used by the ProviderBasedLocalizationService.
Declaration
public IList<LocalizationProvider> Providers { get; protected set; }
Property Value
Type | Description |
---|---|
System.Collections.Generic.IList<LocalizationProvider> | The list of providers. |
Remarks
Note that as the Providers are processed in prioritized order from first to last, you should insert you provider first if you want it to be called first.
Any provider added with a specified name, must have a unique name.
