现在我需要访问 json 的名称、描述和联系方式。请帮助我感到震惊 this.The 指针没有进入酒店 child。
我为 json 使用 JObject，它的工作原理是这样的：
string json = File.ReadAllText("E:/HotelResult.txt");
JObject o = JObject.Parse(json);
string name = (string)o["data"]["name"];
string contactPhone = (string)o["data"]["contact"]["phone"];
希望能帮到你
我只提取了你的部分代码做了一个例子
using System;
using Newtonsoft.Json;
public class Program
{
public static void Main()
{
string cityname = "";
string json = "{\"data\": [{\"type\": \"hotel-offers\",\"hotel\": {\"type\": \"hotel\",\"hotelId\": \"ALNYC647\",\"chainCode\": \"AL\",\"dupeId\": \"501447323\",\"name\": \"Aloft Manhattan Downtown - Financial District\",\"rating\": \"4\",\"cityCode\": \"NYC\",\"latitude\": 40.71041,\"longitude\": -74.00666,\"hotelDistance\": {\"distance\": 0.4,\"distanceUnit\": \"KM\"}}}]}";
dynamic parsedJson = JsonConvert.DeserializeObject(json);
cityname = parsedJson.data[0].hotel.name;
Console.WriteLine(cityname);
}
}
同时复制动态和城市名称可以解决您的问题。您应该注意您的模型可能存在的其他一些问题。
1 - 如果您的 json 数据中有多行，您将只会获得最后一个城市名称。你会失去所有其他的
2 - 正如@Marco 在您的评论中指出的那样，实际映射 json
会更好

现在我需要访问 json 的名称、描述和联系方式。请帮助我感到震惊 this.The 指针没有进入酒店 child。
我为 json 使用 JObject，它的工作原理是这样的：
string json = File.ReadAllText("E:/HotelResult.txt");
JObject o = JObject.Parse(json);
string name = (string)o["data"]["name"];
string contactPhone = (string)o["data"]["contact"]["phone"];
希望能帮到你
我只提取了你的部分代码做了一个例子
using System;
using Newtonsoft.Json;
public class Program
{
public static void Main()
{
string cityname = "";
string json = "{\"data\": [{\"type\": \"hotel-offers\",\"hotel\": {\"type\": \"hotel\",\"hotelId\": \"ALNYC647\",\"chainCode\": \"AL\",\"dupeId\": \"501447323\",\"name\": \"Aloft Manhattan Downtown - Financial District\",\"rating\": \"4\",\"cityCode\": \"NYC\",\"latitude\": 40.71041,\"longitude\": -74.00666,\"hotelDistance\": {\"distance\": 0.4,\"distanceUnit\": \"KM\"}}}]}";
dynamic parsedJson = JsonConvert.DeserializeObject(json);
cityname = parsedJson.data[0].hotel.name;
Console.WriteLine(cityname);
}
}
同时复制动态和城市名称可以解决您的问题。您应该注意您的模型可能存在的其他一些问题。
1 - 如果您的 json 数据中有多行，您将只会获得最后一个城市名称。你会失去所有其他的
2 - 正如@Marco 在您的评论中指出的那样，实际映射 json
会更好
