从 LINQ 查询填充磁贴（Web 服务）

Question

我目前正在从硬编码的数据中填充我的 Windows 磁贴（我想确保我可以先让它工作......）。我所拥有的...它适用于硬编码信息。

我想要尝试做的是从我的 LINQ 查询中提取信息并将它们放入几个变量中，然后将这些变量放入 Tile。

我正在使用网络服务来联系我的 SQL 数据库，并将提供该服务以及我所拥有的以下信息：

网络服务

[OperationContract]
List<TBL_My_Info> FindInfo(string uid);

public List<TBL_My_Info> FindInfo(string uid)
{
    DataClasses1DataContext context = new DataClasses1DataContext();
    var res = from r in context.TBL_My_Info where r.User_Name == uid select r;
    return res.ToList();
}

我可以验证查询是否提取了我需要的 3 条信息，即 Title、Description 和 Author。我遇到的麻烦是将这 3 个部分分配给它们各自的变量，以便我可以在我的磁贴中显示它们。

我的问题是我不确定如何使用我的LINQ 查询结果将它们分配给PrimaryTile..中的变量。

这是我硬编码磁贴的值以确保它正确显示的地方：

private void UpdatePrimaryTile(object sender, Windows.UI.Xaml.RoutedEventArgs e)
    {
        var xmlDoc = TileService.CreateTiles(new PrimaryTile());
        var updater = TileUpdateManager.CreateTileUpdaterForApplication();
        TileNotification notification = new TileNotification(xmlDoc);
        updater.Update(notification);
    }


public class PrimaryTile
{
    public string time { get; set; } = "8:15 AM, Saturday";
    public string message { get; set; } = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore.";
    public string message2 { get; set; } = " At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident.";
    public string branding { get; set; } = "name";
    public string appName { get; set; } = "HoL";
}


public static Windows.Data.Xml.Dom.XmlDocument CreateTiles(PrimaryTile primaryTile)
    {
        XDocument xDoc = new XDocument(
            new XElement("tile", new XAttribute("version", 3),
                new XElement("visual",
                    // Small Tile 
                    new XElement("binding", new XAttribute("branding",

                                )
                            )
                        ),
                        // Medium Tile 
                        new XElement("binding", new XAttribute("branding", primaryTile.branding), 
                            new XAttribute("displayName", primaryTile.appName), new XAttribute("template", "TileMedium"),
                                new XElement("group", new XElement("subgroup",

                                   )
                              )
                         )
                    )
                )
            );
        Windows.Data.Xml.Dom.XmlDocument xmlDoc = new Windows.Data.Xml.Dom.XmlDocument();
        xmlDoc.LoadXml(xDoc.ToString());
        return xmlDoc;
    }
