在JSON.NET中解析JSON数组 [英] Parse JSON array in JSON.NET

问题描述

我在REST API响应中有JSON对象:

I have JSON object in REST API response:

{
    Result:
    [
        {
            "id": 1,
            "id_endpoint": 1,
            "name": "Endpoint 1",
            "description": "Endpoint 1",
            "unit": "mmol",
            "minthreshold": 30,
            "maxthreshold": -15,
            "id_device": 4,
            "value": 7,
            "time": "2016-12-24T21:20:19.000Z",
            "address": "Endpoint 1",
            "id_user": 1
        }, {
            "id": 2,
            "id_endpoint": 1,
            "name": "Endpoint 1",
            "description": "Endpoint 1",
            "unit": "mmol",
            "minthreshold": 30,
            "maxthreshold": -15,
            "id_device": 4,
            "value": 6,
            "time": "2016-12-24T21:20:16.000Z",
            "address": "Endpoint 1",
            "id_user": 1
        }, {
            "id": 3,
            "id_endpoint": 1,
            "name": "Endpoint 1",
            "description": "Endpoint 1",
            "unit": "mmol",
            "minthreshold": 30,
            "maxthreshold": -15,
            "id_device": 4,
            "value": 8,
            "time": "2016-12-24T21:18:38.000Z",
            "address": "Endpoint 1",
            "id_user": 1
        }
    ],
    StatusCode: 200
}

如果出现错误，他们将得到:

And if Error, they will get:

{
    Result: null,
    StatusCode: 404
}

我正在使用JSON.NET，并且已将类 DeviceInfo.cs

I'm using JSON.NET and I've class DeviceInfo.cs

public class DeviceInfo
{
    public int DeviceID {get;set;}
    public int EndpointID {get;set;}
    public string DeviceName {get;set;}
    public double MinThreshold {get;set;}
    public double MaxThreshold {get;set;}
    public double CurrentValue {get;set;}
    public DateTime ValueTime {get;set;}
    public string EndpointAddress {get;set;}
    public int IDUser {get;set;}
}

我的问题是如何解析JSON对象中的Result数组并将其存储在DeviceInfo类中?

And my question is how to parse Result array in JSON object and stored it in DeviceInfo class?

推荐答案

您需要属性帮助Newtonsoft.Json将源映射到您的类.

You need attributes help Newtonsoft.Json mapping the source to your class.

public class DeviceInfo
{
    [JsonProperty("id")]
    public int DeviceID { get; set; }
    [JsonProperty("id_endpoint")]
    public int EndpointID { get; set; }
    [JsonProperty("name")]
    public string DeviceName { get; set; }
    [JsonProperty("minthreshold")]
    public double MinThreshold { get; set; }
    [JsonProperty("maxthreshold")]
    public double MaxThreshold { get; set; }
    [JsonProperty("value")]
    public double CurrentValue { get; set; }
    [JsonProperty("time")]
    public DateTime ValueTime { get; set; }
    [JsonProperty("address")]
    public string EndpointAddress { get; set; }
    [JsonProperty("id_user")]
    public int IDUser { get; set; }
}

还有一个封装了您的json的外部类.

And an outer class which your json was wrapped.

public class RootObject
{
    public List<DeviceInfo> Result { get; set; }
    public int StatusCode { get; set; }
}

最后，您可以使用JsonConvert对您的json进行反序列化.

Finally, you can use JsonConvert to Deserialize your json.

var result = JsonConvert.DeserializeObject<RootObject>(json);
