Get value from xml/json file in vb.net

Question

I am using Vb.net and I have written following code to get data using json object deserialization.

abc is a string format and the value is:

 { 
    "state":"success",
     "data"
          {
            "height":200,
            "width":0 
           }
 }


jsonObject = JsonConvert.DesirializeObject(Of xyz)(abc)

Now, I need to get the values of height and/or width based on the condition when the state is successful.

Please help me how can I get the values from inside data.

I tried for status as below:

jsonObject.state = "status" 

But I don't know what to use for data and getting height and width.
