示例

以下示例演示如何使用 IsInRole 方法重载。枚举 WindowsBuiltInRole 用作标识内置角色 (RID) 相对标识符的源。 RID 用于确定当前主体的角色。

public:
   static void DemonstrateWindowsBuiltInRoleEnum()
   {
      AppDomain^ myDomain = Thread::GetDomain();

      myDomain->SetPrincipalPolicy( PrincipalPolicy::WindowsPrincipal );
      WindowsPrincipal^ myPrincipal = dynamic_cast<WindowsPrincipal^>(Thread::CurrentPrincipal);

      Console::WriteLine( "{0} belongs to: ", myPrincipal->Identity->Name );

      Array^ wbirFields = Enum::GetValues( WindowsBuiltInRole::typeid );

      for each ( Object^ roleName in wbirFields )
      {
         try
         {
            Console::WriteLine( "{0}? {1}.", roleName,
               myPrincipal->IsInRole(  *dynamic_cast<WindowsBuiltInRole^>(roleName) ) );
         }
         catch ( Exception^ ) 
         {
            Console::WriteLine( "{0}: Could not obtain role for this RID.",
               roleName );
         }
      }
   }

注解

类 WindowsPrincipal 主要用于检查 Windows 用户的角色。方法 WindowsPrincipal.IsInRole 重载允许使用不同的角色上下文来检查用户角色。
