SimpleGeo - 从响应中获取经度和纬度

Question

我有以下 JSON 格式的响应，但似乎无法弄清楚如何从中获取对数和纬度

我试过了

Dim result = JsonConvert.DeserializeObject(Of Dictionary(Of String, Object))(response.Content)

但是当我尝试获取带有“地址”键的项目时......我什么也没得到

这是 JSON 响应

Answer 1

在这个例子中，我希望有一个名为“query”的键返回另一个字典。那会有经度和纬度的键。

Dim queryDict = result.Item("query")
Dim lng = queryDict.Item("longitude")
Dim lat = queryDict.Item("latitude")

请原谅语法，但我已经很久没有做过 .net/VB 了，所以不知道这是否正确。

如果将您拥有的 JSON 可视化，它也可能对您有所帮助。尝试将其粘贴到此工具中并单击渲染按钮： http://chris.photobooks.com/json/default.htm
