RegistrationServices Class

Provides a set of services for registering and unregistering managed assemblies for use from COM.


Namespace:  System.Runtime.InteropServices
Assembly:  mscorlib (in mscorlib.dll)

public class RegistrationServices : IRegistrationServices

The RegistrationServices type exposes the following members.

Public methodRegistrationServicesInitializes a new instance of the RegistrationServices class.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetManagedCategoryGuidReturns the GUID of the COM category that contains the managed classes.
Public methodGetProgIdForTypeRetrieves the COM ProgID for the specified type.
Public methodGetRegistrableTypesInAssemblyRetrieves a list of classes in an assembly that would be registered by a call to RegisterAssembly.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodRegisterAssemblyRegisters the classes in a managed assembly to enable creation from COM.
Public methodRegisterTypeForComClients(Type, Guid)Registers the specified type with COM using the specified GUID.
Public methodRegisterTypeForComClients(Type, RegistrationClassContext, RegistrationConnectionType)Registers the specified type with COM using the specified execution context and connection type.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodTypeRepresentsComTypeIndicates whether a type is marked with the ComImportAttribute, or derives from a type marked with the ComImportAttribute and shares the same GUID as the parent.
Public methodTypeRequiresRegistrationDetermines whether the specified type requires registration.
Public methodUnregisterAssemblyUnregisters the classes in a managed assembly.
Public methodUnregisterTypeForComClientsRemoves references to a type registered with the RegisterTypeForComClients method.

Registration is needed when the objects within an assembly are being used by COM clients. The Regasm.exe (Assembly Registration Tool) and Microsoft Visual Studio 2005 use methods exposed by the RegistrationServices class to add or remove COM-enabling registry entries for managed assemblies.

You can use the following methods to assist you in preparing a registration file:

Although these methods help in gathering information to be used in a registration file, they do not actually produce a registration file. Instead, you can use the Regasm.exe (Assembly Registration Tool) tool with the /regfile option to perform this task. RegistrationServices methods cannot export and register a type library. To export and register a type library, you can use the Regasm.exe (Assembly Registration Tool) tool and the Tlbexp.exe (Type Library Exporter) tool.
