试试这个..

var backStackList = PageHelper.RootApplicationFrame.BackStack.ToList();

    foreach (var page in backStackList)
    {
        if (!pageName.Contains("MainPage"))
        {
          if (page.SourcePageType.ToString().Contains(pageName))
                {
                    PageHelper.RootApplicationFrame.BackStack.RemoveAt(PageHelper.RootApplicationFrame.BackStack.Count - 1);
                }
         }
     }
