如何在XAML中使用字符串作为this.Frame.Navigate（typeof（）的参数）进行导航？

Question

in Xaml file I have

<ComboBox Grid.Row="2" Grid.Column="2" Margin="50,50,50,50" FontSize="50" SelectionChanged="NavigateKing">
        <ComboBoxItem></ComboBoxItem>
        <ComboBoxItem Content="Prince Wijaya"></ComboBoxItem>
        <ComboBoxItem Content="Pandukabhaya"></ComboBoxItem>
        <ComboBoxItem Content="Dewanampiya Tissa"></ComboBoxItem>
    </ComboBox>

And in Xaml.Cs file

private void NavigateKing(object sender, SelectionChangedEventArgs e)
    {
        ComboBoxItem cbi = (ComboBoxItem)((sender as ComboBox).SelectedItem);
        string navigatingURI = cbi.Content.ToString();
        this.Frame.Navigate(typeof(/*IntendedXaml filename should be here*/);
    } 

Rather than writing a whole if-else or switch-case scenario can I just pass the NavigationURI to navigate?

Try this.

XAML

<ComboBox Margin="50,50,50,50" FontSize="50" SelectionChanged="NavigateKing">
    <ComboBoxItem Content="Prince Wijaya" Tag="BlankPage1"></ComboBoxItem>
    <ComboBoxItem Content="Pandukabhaya" Tag="BlankPage2"></ComboBoxItem>
    <ComboBoxItem Content="Dewanampiya Tissa" Tag="BlankPage3"></ComboBoxItem>
</ComboBox>

C#

private void NavigateKing(object sender, SelectionChangedEventArgs e)
{
    ComboBoxItem cbi = (ComboBoxItem)((sender as ComboBox).SelectedItem);
    string navigatingURI = cbi.Content.ToString();
    this.Frame.Navigate(Type.GetType(this.GetType().Namespace + "." + cbi.Tag.ToString()));
}
