AppDomain.SetPrincipalPolicy(PrincipalPolicy) 方法

定义

指定在此应用程序域中执行时如果线程尝试绑定到用户,用户和标识对象应如何附加到该线程。Specifies how principal and identity objects should be attached to a thread if the thread attempts to bind to a principal while executing in this application domain.

public:
 virtual void SetPrincipalPolicy(System::Security::Principal::PrincipalPolicy policy);
public void SetPrincipalPolicy (System.Security.Principal.PrincipalPolicy policy);
abstract member SetPrincipalPolicy : System.Security.Principal.PrincipalPolicy -> unit
override this.SetPrincipalPolicy : System.Security.Principal.PrincipalPolicy -> unit
Public Sub SetPrincipalPolicy (policy As PrincipalPolicy)

参数

policy
PrincipalPolicy

PrincipalPolicy 值之一,指定要附加到线程的主体对象类型。One of the PrincipalPolicy values that specifies the type of the principal object to attach to threads.

异常

在卸载的应用程序域上尝试该操作。The operation is attempted on an unloaded application domain.

示例

下面的示例演示对使用 SetPrincipalPolicy 方法更改应用程序域的主体策略的线程的影响。The following example shows the effect on threads of using the SetPrincipalPolicy method to change the principal policy of the application domain. 它还显示了使用 SetThreadPrincipal 方法更改可附加到应用程序域中的线程的主体的效果。It also shows the effect of using the SetThreadPrincipal method to change the principal that is available for attaching to threads in the application domain.

注解

仅当你在使用 Thread.CurrentPrincipal 属性之前设置此值时,设置此值才有效。Setting this value will only be effective if you set it before using the Thread.CurrentPrincipal property. 例如,如果将 Thread.CurrentPrincipal 设置为给定主体(例如,一般主体),然后使用 SetPrincipalPolicy 方法将 PrincipalPolicy 设置为 WindowsPrincipal,则当前主体将保留为泛型主体。For example, if you set Thread.CurrentPrincipal to a given principal (for example, a generic principal) and then use the SetPrincipalPolicy method to set the PrincipalPolicy to WindowsPrincipal, the current principal will remain the generic principal.
