Hinweise

IsComObject returns true if the class type of the instance is attributed with System.Runtime.InteropServices.ComImportAttribute or if it derives directly or indirectly from a class attributed with ComImportAttribute. The Tlbimp.exe (Type Library Importer) tool applies this attribute for you when it imports a type library.

Two other methods also determine whether a specified object represents a COM object, but the requirements for returning true differ from this method's requirements. P:System.Type.IsImport returns true if the class (or interface) is attributed with T:System.Runtime.InteropServices.ComImportAttribute directly; it does not return true for derived types. M:System.Runtime.InteropServices.RegistrationServices.TypeRepresentsComType(System.Type) returns true if the type is attributed with T:System.Runtime.InteropServices.ComImportAttribute or derives from a type with the same GUID.
