Parse JSON array in JSON.NET

Question

I have JSON object in REST API response:

{
    Result:
    [
        {
            \"id\": 1,
            \"id_endpoint\": 1,
            \"name\": \"Endpoint 1\         


        

Answer 1

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; }
}

And an outer class which your json was wrapped.

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

Finally, you can use JsonConvert to Deserialize your json.

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

Answer 2

You can use JsonDeserialize to parse json

var array = JsonConvert.DeserializeObject<List<DeviceInfo>>(str);

Answer 3

Please refer to following code:

var response =  JsonConvert.DeserializeObject<Dictionary<string,object>>(JSONstring);

if(response != null && response["StatusCode"] == "200")
{
     List<DeviceInfo> lstResult = JsonConvert.DeserializeObject<List<DeviceInfo>(response["Result"]);
}

I hope this would help.
