Bing 地图 - 无法从 JSON/XML 获取地址以进行反向地理编码

问题描述

有一段简单的代码，给定 LATitude 和 LONgitude，检索地址。 使用可选的 mapquest、ARCGiS 或 BING。在 propertygridBox 中显示结果。

    Dim AdressofPoint As New BingMapsRESTService.Common.JSON.Address
    url = "http://dev.virtualearth.net/REST/v1/Locations/47.64054,-122.12934?&key=" + apikey
    xmlhttpRequest.open("GET",url)
    xmlhttpRequest.send()
    responsetext = xmlhttpRequest.responseText
    'AdressofPoint = Newtonsoft.Json.JsonConvert.DeserializeObject(Of BingMapsRESTService.Common.JSON.Address)(responsetext)
    AdressofPoint = System.Text.Json.JsonSerializer.Deserialize(Of BingMapsRESTService.Common.JSON.Address)(responsetext)
    Return AdressofPoint ' to set the Selectedobject property of propertygrid object) (System.Windows.Forms.PropertyGrid)

Simple Screenshot

ARCGIS 和 mapquest 很好，BING 的问题是属性网格框显示字段名称但不显示值。所有返回的值（Admindistrict、locality、postalcode.....）都是空的（什么都没有）。这似乎是一个反序列化问题。由于它是几行代码，我尝试了许多不同的版本，例如：

• 输出 XML / JSON
• 从返回的 JSON 创建类（粘贴 Json 作为 VS2019) / 实施数据契约 https://docs.microsoft.com/en-us/bingmaps/rest-services/json-data-contracts
• System.Text / NewtonSoft 解串器

返回的 responsetext（或 responsexml）没有问题，并且包含值！
