How to deserialize or parse the Json object into an array...

Mohd Taufeeque

{

"shapes":[{"id":"A","cursor":"pointer","visual":null,"x":69.25,"y":50},{"name":"Right"},{"name":"Auto"}],"width":10,"height":10},"undoable":true}],

"connections":[{"id":"8Op6PApGWW","selectable":true,"serializable":true,"from":{"shapeId":"A"},"toX":null,"toY":null,"to":{"shapeId":"B"}}]

This is my json data.

I have to deserialize the data into an array format so i can access the from and to value of connections.

like var fromid=connections[0].from;

There are more than one shape and connections.

What I have tried is:

string jsonString = diagram.ResponseData.diagramJson;

JArray jsondata = (JArray)JsonConvert.DeserializeObject(jsonString);

But It will throw an error.

{"Unable to cast object of type 'Newtonsoft.Json.Linq.JObject' to type 'Newtonsoft.Json.Linq.JArray'."}

Is anything wrong while deserializing.

Can you show how the JSON looks with 2 shapes and connections?

Read attribute by attribute and use Split(":").

The JSON is an object, containing a property named shapes, which is an array.

JObject jsondata = (JObject)JsonConvert.DeserializeObject(jsonString);

Now you should be able to use the array jsonData.shapes.

You can probably do this:

string jsonArray = JsonConvert.SerializeObject(jsonData.shapes);
JArray data = (JArray)JsonConvert.DeserializeObject(jsonArray);

A much better option would be to create some classes to map to your JSON and use those instead.
