Keterangan

Perhatian

Keamanan Akses Kode (CAS) tidak digunakan lagi di semua versi .NET Framework dan .NET. Versi terbaru .NET tidak mematuhi anotasi CAS dan menghasilkan kesalahan jika API terkait CAS digunakan. Pengembang harus mencari cara alternatif untuk menyelesaikan tugas keamanan.

Anda dapat menggunakan PermissionSet untuk melakukan operasi pada beberapa izin yang berbeda sebagai grup.

Konstruktor

PermissionSet(PermissionSet)	Kedaluwarsa. Menginisialisasi instans PermissionSet baru kelas dengan nilai awal yang permSet diambil dari parameter .
PermissionSet(PermissionState)	Kedaluwarsa. Menginisialisasi instans PermissionSet baru kelas dengan yang ditentukan PermissionState.

Properti

Count	Kedaluwarsa. Mendapatkan jumlah objek izin yang terkandung dalam kumpulan izin.
IsReadOnly	Kedaluwarsa. Mendapatkan nilai yang menunjukkan apakah koleksi bersifat baca-saja.
IsSynchronized	Kedaluwarsa. Mendapatkan nilai yang menunjukkan apakah koleksi dijamin aman untuk utas.
SyncRoot	Kedaluwarsa. Mendapatkan objek akar dari koleksi saat ini.

Metode

AddPermission(IPermission)	Kedaluwarsa. Menambahkan izin tertentu ke PermissionSet.
AddPermissionImpl(IPermission)	Kedaluwarsa. Menambahkan izin tertentu ke PermissionSet.
Assert()	Kedaluwarsa. Menyatakan bahwa kode panggilan dapat mengakses sumber daya yang dilindungi oleh permintaan izin melalui kode yang memanggil metode ini, bahkan jika penelepon yang lebih tinggi di tumpukan belum diberikan izin untuk mengakses sumber daya. Menggunakan Assert() dapat membuat kerentanan keamanan.
ContainsNonCodeAccessPermissions()	Kedaluwarsa. Mendapatkan nilai yang menunjukkan apakah PermissionSet berisi izin yang tidak berasal dari CodeAccessPermission.
ConvertPermissionSet(String, Byte[], String)	Kedaluwarsa. Mengonversi yang dikodekan PermissionSet dari satu format pengodean XML ke format pengodean XML lainnya.
Copy()	Kedaluwarsa. Membuat salinan PermissionSet.
CopyTo(Array, Int32)	Kedaluwarsa. Menyalin objek izin dari set ke lokasi yang ditunjukkan dalam Array.
Demand()	Kedaluwarsa. SecurityException Memaksa pada durasi jika semua penelepon yang lebih tinggi dalam tumpukan panggilan belum diberikan izin yang ditentukan oleh instans saat ini.
Deny()	Kedaluwarsa. Menyebabkan setiap Demand() yang melewati kode panggilan untuk izin yang memiliki persimpangan dengan izin jenis yang terkandung dalam saat ini PermissionSet gagal.
Equals(Object)	Kedaluwarsa. Menentukan apakah objek atau NamedPermissionSet yang ditentukan PermissionSet sama dengan saat iniPermissionSet.
FromXml(SecurityElement)	Kedaluwarsa. Merekonstruksi objek keamanan dengan status tertentu dari pengodean XML.
GetEnumerator()	Kedaluwarsa. Mengembalikan enumerator untuk izin set.
GetEnumeratorImpl()	Kedaluwarsa. Mengembalikan enumerator untuk izin set.
GetHashCode()	Kedaluwarsa. Mendapatkan kode hash untuk PermissionSet objek yang cocok untuk digunakan dalam algoritma hash dan struktur data seperti tabel hash.
GetPermission(Type)	Kedaluwarsa. Mendapatkan objek izin dari jenis yang ditentukan, jika ada dalam set.
GetPermissionImpl(Type)	Kedaluwarsa. Mendapatkan objek izin dari jenis yang ditentukan, jika ada dalam set.
GetType()	Kedaluwarsa. Mendapatkan dari instans Type saat ini. (Diperoleh dari Object)
Intersect(PermissionSet)	Kedaluwarsa. Membuat dan mengembalikan set izin yang merupakan persimpangan dari saat ini PermissionSet dan yang ditentukan PermissionSet.
IsEmpty()	Kedaluwarsa. Mendapatkan nilai yang menunjukkan apakah PermissionSet kosong.
IsSubsetOf(PermissionSet)	Kedaluwarsa. Menentukan apakah saat ini PermissionSet adalah subset dari yang ditentukan PermissionSet.
IsUnrestricted()	Kedaluwarsa. Menentukan apakah PermissionSet adalah Unrestricted.
MemberwiseClone()	Kedaluwarsa. Membuat salinan dangkal dari saat ini Object. (Diperoleh dari Object)
PermitOnly()	Kedaluwarsa. Menyebabkan setiap Demand() yang melewati kode panggilan untuk setiap PermissionSet yang bukan subset dari saat ini PermissionSet gagal.
RemovePermission(Type)	Kedaluwarsa. Menghapus izin jenis tertentu dari set.
RemovePermissionImpl(Type)	Kedaluwarsa. Menghapus izin jenis tertentu dari set.
RevertAssert()	Kedaluwarsa. Menyebabkan bingkai sebelumnya Assert() dihapus dan tidak lagi berlaku.
SetPermission(IPermission)	Kedaluwarsa. Mengatur izin ke PermissionSet, menggantikan izin yang ada dari jenis yang sama.
SetPermissionImpl(IPermission)	Kedaluwarsa. Mengatur izin ke PermissionSet, menggantikan izin yang ada dari jenis yang sama.
