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.

Kehadiran GacInstalled bukti menghasilkan GacIdentityPermission dalam set hibah. Jika ada Demand untuk GacIdentityPermission, GacIdentityPermission yang sesuai dengan GacInstalled bukti dibandingkan dengan izin yang diminta.

Konstruktor

GacInstalled()

Kedaluwarsa. Menginisialisasi instans baru kelas GacInstalled.

Metode

Clone()	Kedaluwarsa. Membuat objek baru yang merupakan salinan lengkap instans saat ini. (Diperoleh dari EvidenceBase)
Copy()	Kedaluwarsa. Membuat salinan yang setara dari objek saat ini.
CreateIdentityPermission(Evidence)	Kedaluwarsa. Membuat izin identitas baru yang sesuai dengan objek saat ini.
Equals(Object)	Kedaluwarsa. Menunjukkan apakah objek saat ini setara dengan objek yang ditentukan.
GetHashCode()	Kedaluwarsa. Mengembalikan kode hash untuk objek saat ini.
GetType()	Kedaluwarsa. Mendapatkan instans Type saat ini. (Diperoleh dari Object)
MemberwiseClone()	Kedaluwarsa. Membuat salinan dangkal dari yang saat ini Object. (Diperoleh dari Object)
ToString()	Kedaluwarsa. Mengembalikan representasi string dari objek saat ini.
