Windows phone 7 将XML转换为地图上的PIN

所以我需要在网站上做什么-但在电话上-我不太确定你的问题是什么，但我认为你的图钉绑定不起作用 您已在ObservableCollection上实现INotifyPropertyChanged。那没必要。要使其工作，必须在PinModel上实现它，并在设置Location属性时调用RaisePropertyChanged方法 您的PinModel类应该如下所示，以使绑定工作（尽管您的绑定现在可能正在工作，因为您将它作为一个整体绑定一次）
还要注意，对linq查询调用的het.Single（）方法返回的是单个值，而不是列表。请看一下Lance关于如何构造linq查询的答案。（有关.Single（）文档，请参见此）您检查过LINQ方法的输出了吗？您似乎只在列表中创建了一个实例。尝试此方法，而不是当前的解析方法
var locations = (from n in doc.Descendants(ns + "ArrayOfStop")
select new RootContainer
{
Location = (from s in n.Elements(ns + "Stop")
select new Location
{
latitude = s.Element(ns + "Lat").Value + " ," + s.Element(ns + "Long").Value,
// longitude = s.Element(ns + "Long").Value,
}).ToList()
});
您好，我正在尝试获取站点列表，它们的lat和long被生成为一个列表，即纬度。然后我希望所有的站点都显示在地图上。我已经更改了pinModel，请参见编辑…可以；我看不出我可以把RaisePropertyChanged放在哪里，但它没有显示为错误OK，oi已经更新了，但是站点仍然没有在地图上填充。这一切都起作用了，这输出了位置，它将它们作为一个图钉。似乎发生的是，你的所有位置都被放在你的ObservableCollection中的一个项目中。即使在输出列表框中，它也会显示所有值，但它仍然是单个项。好的，我如何才能不将它们作为单个项来获取？这应该会有所帮助：
