      "geometry":{  
        "bounds":{  
          "northeast":{  
            "lat":53.135115,
            "lng":-1.1843116
          },
          "southwest":{  
            "lat":53.1334688,
            "lng":-1.1865058
          }
        },
        "location":{  
          "lat":53.1343937,
          "lng":-1.1849156
        },
        "location_type":"APPROXIMATE",
        "viewport":{  
          "northeast":{  
            "lat":53.1356408802915,
            "lng":-1.184059719708498
          },
          "southwest":{  
            "lat":53.1329429197085,
            "lng":-1.186757680291502
          }
        }
      },
      "types":[  
        "postal_code"
      ]
    }
  ],
  "status":"OK"
}

Open in new window


I want the Lat & Lng values from the location_type":"APPROXIMATE", section??
 Heres my Code:

       
Dim result = JsonConvert.DeserializeObject(x)
        Dim lat
        com = result("results")("approximate")("lat")

Open in new window

have you thought about using json.net?

once you have your class objects defined, it makes it a lot easier in working with them and accessing all of the data

hi,

Ive spen all day just getting the right references installed etc ;)
Im happy using 'Newtonsoft.Json', I just dont know how to reference the json itself.

Using this Json and this code It works :
{'books':[{'title':'HarryPotter','pages':'134'}]}
Console.WriteLine(result("books")(0)("title") & " - " & result("books")(0)("pages"))

I jusy dont know how to structure the results line to access the other data

good point Eric, I don't believe they were.

You'll need to download it, then add a reference. Look at the installation doc on the web site for specifics
