Параметры

Base
Тип: System.Object

Required. The class from which to derive implementation.

Position
Тип: System.Object

Optional. Default = 0. The code element after which to add the new element. If the value is a CodeElement, then the new element is added immediately after it.

If the value is a Long data type, then AddBase indicates the element after which to add the new element.

Because collections begin their count at 1, passing 0 indicates that the new element should be placed at the beginning of the collection. A value of -1 means the element should be placed at the end.

Возвращаемое значение

Тип: EnvDTE.CodeElement

A CodeElement object.

Заметки

The correctness of the arguments is determined by the language behind the code model. AddBase fails for Visual J# class if there is already a declared base class; you must first remove the existing one with CodeType.RemoveBase.

AddBase returns a CodeElement object rather than a CodeType to accommodate Visual C++, and the Kind of the returned object is vsCMElementVCBase for the implementation of Visual C++.
