问题描述
我正在尝试使用以下代码使用Google 反向地理编码：
I am trying to use Google Reverse Geocoding using below code:
var client = new HttpClient();
client.BaseAddress = new Uri("https://maps.googleapis.com/maps/api/geocode/json?latlng=25.2547667,55.290913&key=AIzaSyC3-0U0ngwYwfFhPeofMtm_C4VhIBMt77A&language=ar");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = await client.GetAsync("https://maps.googleapis.com/maps/api/geocode/json?latlng=25.2547667,55.290913&key=AIzaSyC3-xxxxxxxxx&language=ar");
if (response.IsSuccessStatusCode)
{
var data = await response.Content.ReadAsStringAsync();
dynamic storydata = JsonConvert.DeserializeObject(data);
LabelCity.Text = storydata[0].results.address_components[0].long_name[2];
}
并低于结果。我想知道怎样才能将 results-> address_components [2] - > long_name读入Label控件？
and getting below result. I want to know how can I read the results->address_components[2]->long_name into a Label control?
结果如下：

推荐答案
嗨Jassim Rahma，
Hi Jassim Rahma,
感谢您发布此处。
根据您的文件，我创建了一个JSON文件来存储它。如果你想获得第一个address_components的第三个long_time值Bur Dubai，请尝试下面的代码。
According to your file, I create a JSON file to store it. And if you want to get the third long_time value Bur Dubai of first address_components, please try the code below.
string path = @"D:\Visual Studio 2017\Projects\ConsoleApp\ConsoleApp\get data from JSON.json";
using (StreamReader sr = new StreamReader(path))
{
string data = sr.ReadToEnd();
JObject obj = JObject.Parse(data);
string longTime = (string)obj["results"][0]["address_components"][2]["long_name"];
}
我认为你把[0]，[2]置于错误的位置。
I think you put the [0],[2] in wrong place.
最好的问候，
Wendy
