Hi,
For that you can add a Ilist as explained below:
IList<string> name = new List<string>();
name.Add("Nick");
name.Add("Pamila");
JArray usersArray = new JArray ();
for (int i = 0; i < name.Count; i++) {
String currentUser = (String)name[i];
usersArray.Add (currentUser.ToString());
}
Dictionary<String, object> jsonObjectMatch = new Dictionary<String, object>();
jsonObjectMatch.Add ("opName", usersArray);
Let me know if it will works for you or need any other assitance regarding this.
Thanks.
