SettingsCommand Classe

Definizione

Spazio dei nomi:

Windows.UI.ApplicationSettings

Nota

SettingsPane è deprecato e potrebbe non funzionare in tutte le versioni di Windows 10. Invece di usare settingsPane, integrare le opzioni delle impostazioni nell'esperienza dell'app. Per altre info, vedi Linee guida per le impostazioni dell'app.

Crea un oggetto comando settings che rappresenta una voce di impostazioni. Questo comando di impostazioni può essere aggiunto al vettore ApplicationCommands .

Nota

Questa classe non è agile, il che significa che è necessario considerare il modello di threading e il comportamento di marshalling. Per altre informazioni, vedere Threading e marshalling (C++/CX) e Uso di oggetti Windows Runtime in un ambiente multithreading (.NET).
