以下是一个简单的WPF示例，演示如何在三个Page之间进行导航切换，使用Frame控件作为导航容器，并包含基本的导航按钮（前进/后退/主页）
Page类更简单，比Window更精简。
代码见下文以及资源文件：

本例介绍如下界面实现：
一、Page的显示
Page可以放到Frame中。
1), Frame的 NavigationUIVisibility ="Visible" 可以显示导航的小图标。
<Frame x:Name="MainFrame" Grid.Column="1" NavigationUIVisibility="Visible"/>
2）.使用Frame的Navigate方法可以导航到某个页面，如下文
MainFrame.Navigate(new Page1());
3）页面之间跳转可以使用超级链接或者NavigationService.Navigate实现，
a). NavigationService
NavigationService.Navigate(new Page3());
其中NavigationService：获得了页的宿
b). 使用Frame的GoBack,GoForward函数
if (MainFrame.CanGoBack)
MainFrame.GoBack();
if (MainFrame.CanGoForward)
MainFrame.GoForward();
c). 超级链接
<TextBlock Margin="10">
click <Hyperlink NavigateUri="Page3.xaml" > 这儿</Hyperlink> 到页面3
</TextBlock>
如果想对URi做验证，可以添加事件RequestNavigate 来处理具体的导航请求。
<TextBlock Margin="10">
click <Hyperlink NavigateUri="Page3.xaml" RequestNavigate="Hyperlink_RequestNavigate"> 这儿</Hyperlink> 到页面3
</TextBlock>
private void Hyperlink_RequestNavigate(object sender, RequestNavigateEventArgs e)
{
if (e.Uri != null)
{
// 获取当前NavigationService并导航
var navService = NavigationService.GetNavigationService((DependencyObject)sender);
navService?.Navigate(new Uri(e.Uri.ToString(), UriKind.RelativeOrAbsolute));
e.Handled = true; //设置为 true 表示事件已处理
}
}
关于参数 RequestNavigateEventArgs：
| 属性/方法 | 说明 |
|---|---|
e.Uri |
获取Hyperlink中指定的目标URI（如 NavigateUri="Page2.xaml"） |
e.Handled |
设置为 true 表示事件已处理，阻止默认行为（必须设置！） |
e.Source |
事件源（即Hyperlink控件本身） |
二、代码如下
