How to deserialize nested json

I have two APIs:

  1. GetDeviceInfo(string addr), which returns JSON data for a single device as follows:

    {
  "DeviceName": "TCatPlcCtrl",
  "TurbineName": "WTG2",
  "State": "run",
  "TurbineType": "1500",
  "Version": "2.11.1816"
}

  2. GetAllDeviceInfo(), which returns a collection of device data with IP addresses:

    {
  "192.168.151.1": {
    "DeviceName": "TCatPlcCtrl",
    "TurbineName": "WTG2",
    "State": "run",
    "TurbineType": "1500",
    "Version": "2.11.1816"
  },
  "192.168.151.33": {
    "DeviceName": "TCatPlcCtrl",
    "TurbineName": "WTG2",
    "State": "stop",
    "TurbineType": "1500",
    "Version": "2.11.2216"
  }
}

For API GetDeviceInfo(string addr), I have tried NewtonSoft.Json and got correct data by calling JsonConvert.DeserializeObject<ModelClass>(content).

But I dont know how to deserialize nested JSON data returned by the GetAllDeviceInfo() API.

Assuming your model class is defined like this:

public class DeviceInfo
{
    public string DeviceName { get; set; }
    public string TurbineName { get; set; }
    public string State { get; set; }
    public string TurbineType { get; set; }
    public string Version { get; set; }
}

Then, for the first JSON, you can deserialize like this:

var device = JsonConvert.DeserializeObject<DeviceInfo>(json);

And for the second case, you can deserialize to a dictionary, where the keys are the IP addresses, and the values are the devices:

var dict = JsonConvert.DeserializeObject<Dictionary<string, DeviceInfo>>(json2);
