AppDomain.SetThreadPrincipal(IPrincipal) メソッド

定義

アプリケーション ドメインでスレッドを実行中に、スレッドがプリンシパルにバインドしようとした場合に、そのスレッドに関連付ける既定のプリンシパル オブジェクトを設定します。Sets the default principal object to be attached to threads if they attempt to bind to a principal while executing in this application domain.

public:
 virtual void SetThreadPrincipal(System::Security::Principal::IPrincipal ^ principal);
public void SetThreadPrincipal (System.Security.Principal.IPrincipal principal);
abstract member SetThreadPrincipal : System.Security.Principal.IPrincipal -> unit
override this.SetThreadPrincipal : System.Security.Principal.IPrincipal -> unit
Public Sub SetThreadPrincipal (principal As IPrincipal)

パラメーター

principal
IPrincipal

スレッドに関連付けるプリンシパル オブジェクト。The principal object to attach to threads.

例外

principalnullです。principal is null.

スレッドのプリンシパルが既に設定されています。The thread principal has already been set.

アンロードされたアプリケーション ドメインで操作しようとします。The operation is attempted on an unloaded application domain.

次の例は、SetThreadPrincipal メソッドを使用して、アプリケーションドメインで実行されているスレッドにアタッチできるプリンシパルを変更した場合の効果を示しています。The following example shows the effect of using the SetThreadPrincipal method to change the principal that is available for attaching to threads that are executing in the application domain. また、SetPrincipalPolicy メソッドを使用して、アプリケーションドメインのプリンシパルポリシーを変更するスレッドへの影響についても示します。It also shows the effect on threads of using the SetPrincipalPolicy method to change the principal policy of the application domain.
