Question

Windows 8应用程序 - metro应用程序 - 您好我想从网络更新平铺图像，但我无法让它工作。我用这个Link 我只进行了一些小的自定义，但网络上的图像不适合我。我有字符串src1中的图像，如果我使用 const字符串src1 =“ms-appx：///Assets/clock24x24.png”; 然后图像工作，但从网络它不工作。有没有人有一些想法？

        var tileUpdater = TileUpdateManager.CreateTileUpdaterForApplication();
        var plannedUpdated = tileUpdater.GetScheduledTileNotifications();
        DateTime now = DateTime.Now;
        DateTime planTill = now.AddHours(4);

        DateTime updateTime = new DateTime(now.Year, now.Month, now.Day, now.Hour, now.Minute, 0).AddMinutes(1);
        if (plannedUpdated.Count > 0)
            updateTime = plannedUpdated.Select(x => x.DeliveryTime.DateTime).Union(new [] { updateTime }).Max();
        string xml = "<tile>"

        documentNow.LoadXml(tileXmlNow);

        tileUpdater.Update(new TileNotification(documentNow) { ExpirationTime = now.AddMinutes(1) });

        for (var startPlanning = updateTime; startPlanning < planTill; startPlanning = startPlanning.AddMinutes(1))
        {
            Debug.WriteLine(startPlanning);
            Debug.WriteLine(planTill);

                XmlDocument document = new XmlDocument();
                document.LoadXml(tileXml);

                ScheduledTileNotification scheduledNotification = new ScheduledTileNotification(document, new DateTimeOffset(startPlanning)) { ExpirationTime = startPlanning.AddMinutes(1) };
                tileUpdater.AddToSchedule(scheduledNotification);

            }
