Bing map API Distance between 2 points

Question

I am trying to get travel distance by car using bing maps api between 2 addresses.

So far I have got the link which returns a JSON file with data but unsure how to get;set; the results to a basic class variable.

Link : var url = "http://dev.virtualearth.net/REST/V1/Routes/Driving?wp.0=11+streetname+parish+city+Postcode&wp.1=3+DestinationStreet+DestinationParish+DestinationPostcode&optimizeWaypoints=true&distanceUnit=mi&key= MY BING API KEY

This returns the following JSON (only part of it):

            },

How can I read this file / set in a class the data such as longitude/latitude and address etc?
