![]() | GetType() | |
![]() | IsDefaultAttribute() | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.) |
![]() | Match(Object^) | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.) |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |

![]() ![]() | _Attribute::GetIDsOfNames(Guid%, IntPtr, UInt32, UInt32, IntPtr) | Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfo(UInt32, UInt32, IntPtr) | Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfoCount(UInt32%) | Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.) |

The following code example shows the use of the PrivateComponentAttribute type.
#using <System.EnterpriseServices.dll> using namespace System; using namespace System::EnterpriseServices; // References: // System.EnterpriseServices // Note: Access checks must be performed at the component level to allow access // to private components. [assembly: ApplicationAccessControl(false, AccessChecksLevel=AccessChecksLevelOption::ApplicationComponent)]; [PrivateComponent] public ref class PrivateComponentAttributeExample : public ServicedComponent { public: void DisplayMessage() { // Display some output. Console::WriteLine("Private component called successfully."); } }; public ref class PrivateComponentAttributeTest : public ServicedComponent { public: static void Test() { // Create a new instance of the example class. PrivateComponentAttributeExample^ example = gcnew PrivateComponentAttributeExample(); // Call a method on the class. example->DisplayMessage(); } };
