Indicates whether a specified object represents a COM object.
Assembly: mscorlib (in mscorlib.dll)
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. Type.IsImport returns true if the class (or interface) is attributed with ComImportAttribute directly; it does not return true for derived types. RegistrationServices.TypeRepresentsComType returns true if the type is attributed with ComImportAttribute or derives from a type with the same GUID.
