Properti

AllResourceMaps	Mendapatkan peta objek ResourceMap yang biasanya terkait dengan paket aplikasi, yang diindeks berdasarkan nama paket.
Current	Mendapatkan ResourceManager untuk aplikasi yang sedang berjalan.
DefaultContext	Mendapatkan ResourceContext default untuk aplikasi yang sedang berjalan. Kecuali ditimpa secara eksplisit, ResourceContext default digunakan untuk menentukan representasi yang paling tepat dari sumber daya bernama yang diberikan. Catatan DefaultContext dapat diubah atau tidak tersedia untuk rilis setelah Windows 8.1. Sebagai gantinya, gunakan ResourceContext.GetForCurrentView.
MainResourceMap	Mendapatkan ResourceMap yang terkait dengan paket utama aplikasi yang sedang berjalan.

Metode

GetAllNamedResourcesForPackage(String, ResourceLayoutInfo)	Mendapatkan daftar semua sumber daya bernama untuk paket aplikasi.
GetAllSubtreesForPackage(String, ResourceLayoutInfo)	Mendapatkan daftar semua koleksi subtree sumber daya untuk paket aplikasi.
IsResourceReference(String)	Menentukan apakah string yang disediakan cocok dengan format referensi sumber daya (pengidentifikasi URI string ms-resource).
LoadPriFiles(IIterable<IStorageFile>)	Memuat satu atau beberapa file Indeks Sumber Daya Paket (PRI) dan menambahkan kontennya ke manajer sumber daya default.
UnloadPriFiles(IIterable<IStorageFile>)	Membongkar satu atau beberapa file Indeks Sumber Daya Paket (PRI).
