This topic is one of the examples used in the Guide to Universal Windows Platform apps . I strongly suggest reading that when getting started with Universal apps.

对于页面标题上的按钮，请使用Windows.UI.Core.SystemNavigationManager并将AppViewBackButtonVisibility属性设置为显示或隐藏按钮，并处理BackRequested事件以执行导航.

For the button on the page header use Windows.UI.Core.SystemNavigationManager and set the AppViewBackButtonVisibility property to show or hide the button and handle the BackRequested event to perform the navigation.

Windows.UI.Core.SystemNavigationManager.GetForCurrentView().AppViewBackButtonVisibility = AppViewBackButtonVisibility.Visible;
Windows.UI.Core.SystemNavigationManager.GetForCurrentView().BackRequested += (s,a) =>
{
    Debug.WriteLine("BackRequested");
    if (Frame.CanGoBack)
    {
        Frame.GoBack();
        a.Handled = true;
    }
}

您可以像在Windows Phone 8.1中一样连接硬件后退按钮，但是您应该检查PhoneContract(或单个类和方法)以确保它在那里:

You wire up the hardware back button the same as you do in Windows Phone 8.1, but you should check for the PhoneContract (or the individual class and method) to make sure it is there:

if (ApiInformation.IsApiContractPresent ("Windows.Phone.PhoneContract", 1, 0)) {  
    Windows.Phone.UI.Input.HardwareButtons.BackPressed += (s, a) =>
    {
        Debug.WriteLine("BackPressed");
        if (Frame.CanGoBack)
        {
            Frame.GoBack();
            a.Handled = true;
        }
    };
}
