參數XAML之間傳遞的Windows Phone

Question

有3個XAML頁面，其中2稱之爲第三頁有不同的參數。我怎樣寫的OnNavigatedTo（）在第三頁？

正在使用NavigationService.Navigate(new Uri("/third.xaml?paramter=xxxx", UriKind.Relative));

Answer 1

借入和從http://msdn.microsoft.com/en-us/library/windowsphone/develop/ff626521(v=vs.105).aspx適於此代碼。

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

    string msg = ""; 

    if (NavigationContext.QueryString.TryGetValue("parameter", out msg)) 
     // now your parameter is in the msg variable, and you could do stuff here. 

    }
