如何收听Visual Studio代码模型事件?

您可能正在寻找通过DTE2对象公开的代码模型事件。对于完全功能化的同步,您还需要处理elementChanged和elementAdded事件:

public void RegisterCodeModelEvents(DTE2 applicationObject)
{
   events = (Events2)applicationObject.Events; //events Must be a field
   codeModelEvents = events.get_CodeModelEvents(null); 

   codeModelEvents.ElementChanged += CodeModelElementChanged;
   codeModelEvents.ElementAdded += CodeModelElementAdded;
   codeModelEvents.ElementDeleted += CodeModelElementDeleted; // this is it!
}

完成后不要忘记删除处理程序:

private void UnregisterCodeModelEvents()
{
    if (codeModelEvents != null)
    {
        codeModelEvents.ElementAdded -= CodeModelElementAdded;
        codeModelEvents.ElementChanged -= CodeModelElementChanged;
        codeModelEvents.ElementDeleted -= CodeModelElementDeleted;
    }
}
