for that particular response, you could use something like this:

    string response = "{\"Realtime Currency Exchange Rate\": {\"1. From_Currency Code\": \"USD\",\"2. From_Currency Name\": \"United States Dollar\",\"3. To_Currency Code\": \"INR\",\"4. To_Currency Name\": \"Indian Rupee\",\"5. Exchange Rate\": \"71.44300000\",\"6. Last Refreshed\": \"2019-02-19 10:01:45\",\"7. Time Zone\": \"UTC\"}}";

var parsedObject = Newtonsoft.Json.JsonConvert.DeserializeObject<JObject>(response);

var actualContent = parsedObject["Realtime Currency Exchange Rate"];
var currencyCode = actualContent.ElementAt(0);
var currencyName = actualContent.ElementAt(1);
.........
var exchangeRate = actualContent.ElementAt(4);

All you need is a reference to Newtonsoft.Json basically
