I also had the issue of parsing and using JSON objects in C   I checked the dynamic type with some libraries  but the issue was always checking if a property exists   In the end  I stumbled upon this web page  which saved me a lot of time  It automatically creates a strongly typed class based on your JSON data  that you will use with the Newtonsoft library  and it works perfectly  It also works with languages other than C
