被覆盖后如何在VSTO内置函数中调用？

Question

在我的 Ribbon.xml 中给出：

<command idMso="FileSave" onAction="SaveIntercept" getEnabled="IsSaveInterceptEnabled" /> 

在我的 Ribbon.cs 中

public void SaveIntercept(IRibbonControl control, ref bool cancelDefault)
{
  if (!IsFileSavedBefore()) <= works :)
  {
    call here build in FileSave 
    (Build in function switch tab when file was never saved before)
    return;
  }
... File was saved before ... continue with my code

}

我已经试过了

RibbonUi.ActivateTabMso("TabSave");

和

Application.CommandBars.ExecuteMso("FileSave");

如何调用原始功能？

Answer 1

也许这行得通？

public void SaveIntercept(IRibbonControl control, ref bool cancelDefault)
{
  if (!IsFileSavedBefore())
  {
    cancelDefault = false;
    return;
  }
  ...
