AppDomain.SetPrincipalPolicy(PrincipalPolicy) Metode

Definisi

Ruang nama:

System

Rakitan:

netstandard.dll, System.Runtime.dll

Sumber:

AppDomain.cs

Menentukan bagaimana objek utama dan identitas harus dilampirkan ke utas jika utas mencoba mengikat ke prinsipal saat menjalankan di domain aplikasi ini.

public:
 void SetPrincipalPolicy(System::Security::Principal::PrincipalPolicy policy);

public void SetPrincipalPolicy(System.Security.Principal.PrincipalPolicy policy);

member this.SetPrincipalPolicy : System.Security.Principal.PrincipalPolicy -> unit

Public Sub SetPrincipalPolicy (policy As PrincipalPolicy)

Parameter

policy

PrincipalPolicy

Salah PrincipalPolicy satu nilai yang menentukan jenis objek utama untuk dilampirkan ke utas.

Pengecualian

AppDomainUnloadedException

Operasi ini dicoba pada domain aplikasi yang tidak dimuat.

Contoh

Contoh berikut menunjukkan efek pada utas menggunakan SetPrincipalPolicy metode untuk mengubah kebijakan utama domain aplikasi. Ini juga menunjukkan efek menggunakan SetThreadPrincipal metode untuk mengubah prinsipal yang tersedia untuk melampirkan ke utas di domain aplikasi.

Keterangan

Mengatur nilai ini hanya akan efektif jika Anda mengaturnya sebelum menggunakan Thread.CurrentPrincipal properti . Misalnya, jika Anda mengatur Thread.CurrentPrincipal ke prinsipal tertentu (misalnya, prinsipal generik) lalu menggunakan SetPrincipalPolicy metode untuk mengatur PrincipalPolicy ke WindowsPrincipal, prinsipal saat ini akan tetap menjadi prinsip generik.
