1, demo How to obtain the package information of the app

Information/packageinfo.xaml.cs

* * Demonstrates how to obtain the package information of the app * * using System;
Using Windows.applicationmodel;
Using Windows.UI.Xaml.Controls;
    
Using Windows.UI.Xaml.Navigation;
        Namespace Xamldemo.information {public sealed partial class Packageinfo:page {public PackageInfo () {this.
        InitializeComponent (); } protected override void Onnavigatedto (NavigationEventArgs e) {Package Package = Packag
            E.current; PackageID PackageID = package.
    
            Id; Lblmsg.text = "Name:" + packageid.name;
            Package name Lblmsg.text + = Environment.NewLine; Lblmsg.text + = "Version:" + packageid.version;
            Version information Lblmsg.text + = Environment.NewLine; Lblmsg.text + = "Architecture:" + packageid.architecture;
            Supported CPU types (X86, ARM, X64, Neutral (all supported), Unknown) Lblmsg.text + = Environment.NewLine; Lblmsg.text + = "Publisher:" + packageid.publisher; Published by Lblmsg.
