If you want to response this result {"msisdn": ["1234","5432"]}

You just replace the variable data with o.

Here is the code :
//string data;
List<string> s = new List<string>();
s.Add("1234");
s.Add("5432");
JArray msisdn = new JArray();
msisdn.Add(s);
JObject o = new JObject();
o["msisdn"] = msisdn;
//var data = o["msisdn"];
Response.Write(o);

1. //string data;
2. List<string> s = new List<string>();
3. s.Add("1234");
4. s.Add("5432");
5. JArray msisdn = new JArray();
6. msisdn.Add(s);
7. JObject o = new JObject();
8. o["msisdn"] = msisdn;
9. var data = o["msisdn"];
10. Response.Write(data);
The type of your variable data is not a string , List is the correct type !
