範例

下列範例示範如何使用 IsInRole 方法多載。 列舉 WindowsBuiltInRole 是用來作為識別內建角色之相對標識符 (RID) 的來源。 RID 可用來判斷目前主體的角色。

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.",
