如何解析JSON数组C#? [英] How to parse a JSON array C#?

问题描述

因此，在执行Web请求之后，我得到了这个JSON字符串:

So after doing a web request, I get this JSON string back:

{"status":"okay","result":[{"id":8810,"country":"IE","region":"07","city":"Dublin","latitude":53.3331,"longitude":-6.2489,"comment":"407367 donkeys"},{"id":9688,"country":"IE","region":"04","city":"Cork","latitude":51.8986,"longitude":-8.4958,"comment":"454765 donkeys"},{"id":9963,"country":"IE","region":"06","city":"Donegal","latitude":54.65,"longitude":-8.1167,"comment":"315518 donkeys"}]}

我不确定如何解析它.我有一个包含ID，国家/地区，地区等的城市类，并且我希望能够将每个类分别保存在列表中，以便可以将它们添加到应用程序的列表视图中.

I'm not sure how to parse it. I have a City class that has id, country, region etc, and I would like to be able to save each one separately in a list so I can add them to a List View for an app.

我已经尝试过了:

JObject jobj = JObject.Parse(jsonString);
JToken jstatus = jobj["status"];
JToken jresult = jobj["result"];
status = (String)jstatus;
JArray arrayOfCities = JArray.Parse(jsonString);

        if (status.Equals("okay"))
        {
            foreach (JObject o in arrayOfCities.Children<JObject>())
            {
                foreach (JProperty p in o.Properties())
                {
                    id = p.Name + p.Value.ToString();// (String)jresult["id"];

                    country = (String)jresult["country"];
                    region = (String)jresult["region"];
                    city = (String)jresult["city"];
                    latitude = (String)jresult["latitude"];
                    longitude = (String)jresult["longitude"];
                    comment = (String)jresult["comment"];
                }
            }
        }

但是，我一直在其中解析错误.我尝试了一些尝试，但最终都没有成功. 我如何分别解析数组的每个部分并将其保存到城市列表". 谢谢

However I keep getting parse errors in it. I tried a few things, but none end up working. How could I parse each part of the array separately and save it to a City List. Thanks

推荐答案

您应使用 DeserializeObject .这是一个示例:

You should use DeserializeObject. Here's an example:

public class CitiesResponse
{
    public string Status { get; set; }
    public List<City> Result { get; set; }
}
var response = JsonConvert.DeserializeObject<CitiesResponse>(jsonString);
// response.Result is your list of cities
