c# – Get value from xml/json file in vb.net

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.

jsonObject.state = "status"

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