I have this string:
[{ \"processLevel\" : \"1\" , \"segments\" : [{ \"min\" : \"0\", \"max\" : \"600\" }] }]
I\'m deserializing the object:
See mridula's answer for why you are getting null. But if you want to directly convert the json string to dictionary you can try following code snippet.
Dictionary values = JsonConvert.DeserializeObject>(json);
