Parsing a JSON response from an API in C#

Question

I called REST API and was able to put the JSON response received back in a String using:

string vResp = new StreamReader(response.GetResponseStream(), Encoding.Default).ReadToEnd();

Below is the result of vResp from Console.WriteLine

{
  "Response" : [ {
    "UserID " : "23123213",
    "UserName " : "dms"
  }, {
    "UserID " : "542515",
    "UserName " : "ark"
  }, {
    "UserID " : "56546",
    "UserName " : "oneim"
  }, {
    "UserID " : "33336536",
    "UserName " : "cyberx"
  }, {
    "UserID " : "7563624",
    "UserName " : "bt"
  }, {
    "UserID " : "1221414",
    "UserName " : "azure"
  } ],
  "count" : "6"
}

I want to parse each UserID and UserName and insert each record in a table but not able to parse correctly. I tried different codes and I am able to separate Response and count but not able to reach one level below. Can anyone please help in this?

Answer 1

Create C# class that match with your vResp json result and then then use JSON.NET to deserialize the JSON data to created C# class objects.

You may refer this tool http://json2csharp.com/ to generate C# class based on your Json data.

Here is the code sample how you can parse Json data into C# class. User userObj = JsonConvert.DeserializeObject(vResp);

Now User will have parsing information and you can insert into table.

Answer 2

install Newtonsoft.Json nuget package and try this code

using Newtonsoft.Json;

.....
jsonDeserialized = JsonConvert.DeserializeObject<DataRoot>(json); 

classes

    public class Response
    {
      
        public string UserID { get; set; }

       public string UserName { get; set; }
    }

    public class DataRoot
    {
        public List<Response> Response { get; set; }
        public string count { get; set; }
    }

use for each to see the result

foreach (var item in jsonDeserialized.Response)
{
     Console.WriteLine ( $"UserID : {item.UserID}, UserName: {item.UserName} ");
        
}
