推荐答案

功能性解决方案如下所示:

A functional solution can look like:

MainWindow XAML:

MainWindow XAML:

<StackPanel>
    <Frame Name="frmMainContent" Height="260"
         DataContext="MyPageInformation"
         Source="{Binding}"
         NavigationUIVisibility="Hidden">           
    </Frame>

</StackPanel>

MainWindow CS:

MainWindow cs:

 frmMainContent.Source = new Uri("test1.xaml", UriKind.Relative); // initialize frame with the "test1" view

test1 XAML:

test1 XAML:

<Grid>
    <Button Click="ButtonBase_OnClick" Background="Red" Height="30" Width="100">Go to page 2</Button>
</Grid>

test1 cs:

private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
    {
        NavigationService ns = NavigationService.GetNavigationService(this);
        ns.Navigate(new Uri("test2.xaml", UriKind.Relative));
    }

test2 XAML:

test2 XAML:

  <Grid>
        <Button Click="ButtonBase_OnClick" Width="100" Height="30" Background="RoyalBlue"> Go to page 1</Button>
    </Grid>

test2 cs:

 NavigationService ns = NavigationService.GetNavigationService(this);
            ns.Navigate(new Uri("test1.xaml", UriKind.Relative));

这是使用NavigationService的有效解决方案.

This is a working solution using NavigationService.
