c# XML parsing into a GeoCoordinate

我有这个XML(示例文件):

 <Record counter="1">
      <Fields>
       <Field name="id">4234</Field>
       <Field name="county"></Field>
     </Fields>          
     <Distance>
       <Miles>0.14</Miles>
       <KM>0.22</KM>
     </Distance>
     <Point>
       <Lat>51.498199</Lat>
       <Lon>-0.126334</Lon>
     </Point>
</Record>

我有下面的代码将其全部放在'vList'集合中这一切都很好。但是，我需要在GeoCoordinate中转换纬度和长度。

做这样的事情:

GeoCoordinate Location = new GeoCoordinate(Convert.ToDouble(Lat), Convert.ToDouble(Lon));

并且它需要被暴露，以便xaml页面可以看到它以转换为Pushpins。它需要与vList保持在同一个集合中，以便XML的所有元素保持在一起。我希望这是有意义的。我花了一整天的时间试图解决这个问题，但不知道如何最终将这个地理位置"位置"值添加到我的收藏中。谢谢。
