Question Parse JSON string

[jaykappy]

I have a JSON string being returned from a function. I want to write each of the values to variables and do something with them.

This is the format my JSON is in....
I am simply trying to write the attributes to variables...

I was trying something like this but not working

I try this below and get cant convert object to string

 

[jaykappy]

I GOT IT...


JObject rss = JObject.Parse(ResponsePolygonCheckExists);
string itemTitle = (string)rss["features"][0]["attributes"]["ADDRESSgeocode"];
txt_CHECKifPOlygonExist.Text = itemTitle;

Sure that may work, but how well does that solution scale? Cut and paste to make it scale up?
What happens when you start cutting and pasting and someone makes a typo on one of the field names? You won't find out until runtime.

You can also use the Value method to convert, this also allows selecting a key from a common token, example:

var token = rss.SelectToken("features[0].attributes"); //same as rss["features"][0]["attributes"]
var address = token.Value<string>("ADDRESSgeocode");
var distance= token.Value<int>("DISTANCEparameter");

Any suggestions Skydiver?
