It's not easy to do anything dynamically in C# but I found something here which might help:

No I want to parse the json Using key Value 
for example I want value for a particular Key like in Android or IOS.


because my json is changing dynamically. some time it return string , sometime object and some time List

If the structure itself is fixed but the data changes then, yes, you should be able to parse it using either the DataContractJsonSerializer class (a reference needed to System.Runtime.Serialization.dll):

or the Newtonsoft.Json package which is perhaps the more popular option at present:
