[HttpPost]
public HttpResponseMessage GetAll()
{
            List<IssueModel> issueModelList = new List<IssueModel>();

            try
            {
                IssueBLL issueBLL = new IssueBLL(AdminUserToken);
                issueModelList = issueBLL.GetAllIssueModelList();
            }
            catch(Exception ex)
            {

            }

            string content = ConvertJson.List2Json<IssueModel>(issueModelList);

            HttpResponseMessage result = new HttpResponseMessage { Content = new StringContent(content, Encoding.GetEncoding("UTF-8"), "application/json") };
            return result;
}

public static string List2Json<T>(IList<T> list)
{
      return Newtonsoft.Json.JsonConvert.SerializeObject(list);
}
