you want convert json string native type access it's values, change them, , create new json string data again. there plenty of solutions on internet can find, including many thirt-party libraries. can recommend http://sourceforge.net/projects/jsonlib/?source=directory written myself, , here example how use it:

string jsonstring = "{\"key1\":\"value1\",\"key2\":2}"; // input string jsonobject jsonobject = jsonobject.parse(jsonstring);   // parse string jsonobject["key1"] = 1;                                 // modify key1 jsonobject["key3"] = "value3";                          // add key3 jsonstring = jsonobject.tostring();                     // create json string 

i hope that's looking for. if interesting more information of how use library refer included examples , wiki pages.
