i decided go httpclient , converted collected data directly json string instead of messing array conversion , able work.

public static void addsubscriber(string firstname, string lastname, string email)         {             var addmemberurl = baseurl + "/members/add";             int groupid = 1927094;             string jsonstring = "{\"email\":\"" + email + "\",\"fields\":{\"first_name\":\"" + firstname + "\",\"last_name\":\"" + lastname + "\"},\"group_ids\":[" + groupid + "]}";              using (var httpclient = new httpclient()) {                 try                 {                     httpclient.defaultrequestheaders.authorization = new authenticationheadervalue("basic", convert.tobase64string(                         system.text.asciiencoding.ascii.getbytes(                             string.format("{0}:{1}", publicapikey, privateapikey))));                     httpclient.defaultrequestheaders.accept.clear();                     httpclient.defaultrequestheaders.accept.add(new mediatypewithqualityheadervalue("application/json"));                     httpclient.defaultrequestheaders.add("x-version", "1");                     stringcontent stringcontent = new stringcontent(jsonstring);                     stringcontent.headers.contenttype = new mediatypeheadervalue("application/json");                     var response = httpclient.postasync(addmemberurl, stringcontent);                      var statustext = response.result;                     system.diagnostics.debug.writeline(statustext);                  }                 catch (exception)                 {                     throw;                 }              }         }
