Hello Everyone

 

I need your help. I'm working on windows service on 4.0 version using c# i want to convert string list to json format and pass that json data to third party.

 

My code  is:-  

 

List msisdnlist = new List();

msisdnlist.Add(rdr.GetInt64(0).ToString());

var jsonSerialiser = new JavaScriptSerializer();
var result = jsonSerialiser.Serialize(msisdnlist);

 

 and also try this one:-

 

 //var result = Newtonsoft.Json.JsonConvert.SerializeObject(msisdnlist);

//var result = JsonConvert.SerializeObject(msisdnlist); 

 

now my problem is i'm not gatting the data in correct format and how to pass that data to third party.

 

 data format which i'm gatting is-

["919464522803","919445453803"]

 

but i want this format -

{"msisdn": ["9418451354", "9617853673"]}
