Create class from Nested JSON with code re usability in C#

Question

I have JSON data coming as

{ "ResultOne":{ "Value1":2,"Value2":3,"Type":"SimpleAdd","Result":5}}

Few other JSON data as

{ "ResultTwo":{ "Value1":2,"Value2":3,"Type":"SimpleSubtract","Result":-1}}

{ "ResultThree":{ "Value1":2,"Value2":3,"Type":"SimpleMultiply","Result":6}}

and so on.

So basically, the inner JSON remains the same, while the outer value keeps changing. I use json2csharp.com to generate class (to make things easier).

    public class ResultOne
{
    public int Value1 { get; set; }
    public int Value2 { get; set; }
    public string Type { get; set; }
    public int Result { get; set; }
}

public class RootObject
{
    public ResultOne ResultOne { get; set; }
}

How can I create a class in C# to reuse code (instead of creating multiple properties for each results in Rootobject, may be reflection ? any pointers in the right direction is helpful. thanks.

EDIT: I am actually using a Delegate to call the server to get JSON response.

 delegate Task<RootObject> Operation(int Value1, int Value2);

The delegate is used to pass in as variable in the method below. This Operation opMeth will determine the type of result that we receive. That will depend on the user input. so I cannot use ResultOne, but need a generic result in the method below.

private async Task<string> DoSomeOp(int Value1, int Value2, Operation opMeth)
    {
        var opResult = await opMeth(Value1, Value1);
        string resultValue = opResult.ResultOne.Result;
        return resultValue;
    }

Well, though your JSON is pretty simple and represent simple Dictionary type, you can avoid creating any classes at all, by using dynamic:

using Newtonsoft.Json;
using System;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            var str = "{ \"ResultTwo\":{ \"Value1\":2,\"Value2\":3,\"Type\":\"SimpleSubtract\",\"Result\":-1}}";

            dynamic des = JsonConvert.DeserializeObject(str);
            var val = (int)des.ResultTwo.Value1;
            Console.WriteLine(val);
        }
    }
}
