How can I implement removing the backStack Entry in Metro style applications?

推荐答案

我发现此答案很有用:

如何清除Backstack并重新开始

编写您自己的NavigationService并将导航状态存储在构造函数中.

Write your own NavigationService and store the navigationstate in the constructor.

string state;

public NavigationService(Frame mainFrame)
{
    state = mainFrame.GetNavigationState();

_mainFrame = mainFrame;
_mainFrame.Navigating += _mainFrame_Navigating;
}

然后在服务上实现此方法，并在需要时调用它:

Then implement this method on the service and call it when needed:

    public void ClearBackstack()
    {
        _mainFrame.SetNavigationState(state);
    }
