WP7应用版本升级的实现方法

首先必须要有一个服务提供升级推送查询

// Code to execute when the application is launching (eg, from Start)

        // This code will not execute when the application is reactivated

        private void Application_Launching(object sender, LaunchingEventArgs e)

        {

            updateServiceReference.UpdateSoapClient usp = new updateServiceReference.UpdateSoapClient();

            usp.CheckMobileUpdateCompleted += new EventHandler<updateServiceReference.CheckMobileUpdateCompletedEventArgs>(usp_CheckMobileUpdateCompleted);

            usp.CheckMobileUpdateAsync(1);

        }

 

        void usp_CheckMobileUpdateCompleted(object sender, updateServiceReference.CheckMobileUpdateCompletedEventArgs e)

        {

            if (e.Result == null)

            {

                return;

            }

            System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();

            //string version = System.Reflection.Assembly.GetExecutingAssembly().FullName;

            //获取程序集的版本号，然后去掉.得到数字对比大小

            string version = assembly.GetCustomAttributes(false).OfType<System.Reflection.AssemblyFileVersionAttribute>().First().Version;

            if (int.Parse(e.Result.Ver) > int.Parse(version.Replace(".", "")))

            {

                if (MessageBox.Show(e.Result.UpdateLog, "升级提示", MessageBoxButton.OKCancel) == MessageBoxResult.OK)

                {

                    Microsoft.Phone.Tasks.MarketplaceDetailTask ms = new Microsoft.Phone.Tasks.MarketplaceDetailTask();

                    ms.ContentType = Microsoft.Phone.Tasks.MarketplaceContentType.Applications;

                    ms.ContentIdentifier = e.Result.DownPath;

                    ms.Show();

                }

            }

        }
