WPF page Jump

There are two types of page redirects: windows and page.
1: windows page Jump
Windows page Jump I believe anyone who has learned winform programming knows that you can instantiate the form and then show it. eg: there are two forms: Main and Login. to Click the register button on the Login form and jump to the Main, the code in the Click Event of the Login form is as follows: main Mn = new Main (); Mn. show ();
2: Page Jump: Both foreground jump and background jump can be achieved at the front end:

<TextBlockFontSize = "24" TextWrapping = "Wrap" Margin = "0, 0, 0">

<Hyperlinkx: Name = "LnkPre" NavigateUri = "Page1.xaml" Foreground = "Black">

Enter Page1

</Hyperlink>

</TextBlock>

Background implementation:

NavigationService. GetNavigationService (this). Navigate (new Uri ("Page1.xaml", UriKind. Relative ));

NavigationService. GetNavigationService (this). GoForward (); // backward

NavigationService. GetNavigationService (this). GoBack (); // forward

You can also write this in the background: this. content = new Page1 (); (this is relatively simple, but we recommend that you use the previous one to improve yourself)
In addition, you can jump to the page through windows:

NavigationWindow window = new NavigationWindow ();

Window. Source = new Uri ("Page1.xaml", UriKind. Relative );

Window. Show ();
