json.net has key method?

Question

If my response has key \"error\" I need to process error and show warning box.

Is there \"haskey\" method exists in json.net? Like:

var x= JObject.P         


        

Answer 1

JObject.ContainsKey(string propertyName) has been made as public method in 11.0.1 release
