c＃在UWP中将数据从一个xaml移到另一个xaml

Question

It is a possibility to move data from one xaml to another xaml?

On MainPage I have textbox where I can write numbers and button which add "5" and navigate to Page1, on Page1 I have textblock where I want to show result.

eg MainPage

textbox = 5, press button

Page1 textblock = 10

I couldn't find any information about UWP.

You can share data between pages by passing parameters.

var value = int.Parse(textbox.Text) + 5; // make sure you handle faulty input
Frame.Navigate(typeof(Page1), value);

and in Page1 , you can access that value with this override:

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    base.OnNavigatedTo(e);

    var value = (int)e.Parameter; // this should be 10

    // ... do what you need with that value
}
