update json object in c# -

i have json object like

{ "name" : "sai", "age" : 22, "salary" : 25000} 

i want update json object by

`{ "name" : "sai", "age" : 23, "gender" : "male"}` 

then want result

{ "name" : "sai", "age" : 23, "salary" : 25000, "gender" : "male"} 

i tried like

foreach(var item in actualjson) { bool isfound = false; foreach(var newitem in newjson) {   if(item == newitem)  // returns false, wrong this? { isfound = true; break; } } if(!isfound) { // add json } } 

i not getting idea solve this?

any help/guidance appreciated.

with json.net can this:

        var json1 = "{ \"name\" : \"sai\", \"age\" : 22, \"salary\" : 25000}";         var json2 = "{ \"name\" : \"sai\", \"age\" : 23, \"gender\" : \"male\"}";          var object1 = jobject.parse(json1);         var object2 = jobject.parse(json2);          foreach (var prop in object2.properties())         {             var targetproperty = object1.property(prop.name);              if (targetproperty == null)             {                 object1.add(prop.name, prop.value);             }             else             {                 targetproperty.value = prop.value;             }         }          var result = object1.tostring(formatting.none); 

this either add property of json2 json1 if doesn't exist or update value if exists.
