I have a REST API that sends the following answer in json format and I want to go through it in order to add a listview to what I go through.

{
"resultado": "OK",
"datos": [
{
  "Pago": "1500.00",
  "Fecha": "2018-09-27"
},
{
  "Pago": "900.00",
  "Fecha": "2018-10-16"
}
]
}

The server's response deserializo asi:

dynamic msjdes = JsonConvert.DeserializeObject(responseText);

Where msjdes is the json format already in c # and it appears as I put it up.
How do I go through it to add them as Item to a listview?
Thank you very much ...

You have to deserialize a class

using System;
using Newtonsoft.Json;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        string json = "{\r\n\"resultado\": \"OK\",\r\n\"datos\": [\r\n{\r\n  \"Pago\": \"1500.00\",\r\n  \"Fecha\": \"2018-09-27\"\r\n},\r\n{\r\n  \"Pago\": \"900.00\",\r\n  \"Fecha\": \"2018-10-16\"\r\n}\r\n]\r\n}";

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

        foreach(var item in  result.datos){
            Console.WriteLine(item.Pago);
        }


    }
}

public class Dato
{
    public string Pago { get; set; }
    public string Fecha { get; set; }
}

public class RootObject
{
    public string resultado { get; set; }
    public List<Dato> datos { get; set; }
}

As you will see when typing the deserialization you have access to the properties you could also do with the dynamic, only you will not have intellisense in the code
