Deserialize Json Array Object to DataTable

Use Below Code

protected void GetCustomerType()
        {
            String serverurl = "API URL";
            Uri myUri = new Uri(serverurl);
            HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(myUri);
            httpWebRequest.ContentType = "application/json";
            httpWebRequest.Method = "GET";

            HttpWebResponse httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
            Stream dataStream = httpResponse.GetResponseStream();
            StreamReader reader = new StreamReader(dataStream);
            string sResponse = reader.ReadToEnd();

            DataTable dt = JsonStringToDataTable(sResponse);
            foreach (DataRow dr in dt.Rows)
            {
                String name = dr[""].ToString();
                String telephone = dr[""].ToString();
                String email = dr[""].ToString();
            }

                    }
        public DataTable JsonStringToDataTable(string jsonString)
        {
            DataTable dt = new DataTable();
            string[] jsonStringArray = Regex.Split(jsonString.Replace("[", "").Replace("]", ""), "},{");
            List<string> ColumnsName = new List<string>();
            foreach (string jSA in jsonStringArray)
            {
                string[] jsonStringData = Regex.Split(jSA.Replace("{", "").Replace("}", ""), ",");
                foreach (string ColumnsNameData in jsonStringData)
                {
                    try
                    {
                        int idx = ColumnsNameData.IndexOf(":");
                        string ColumnsNameString = ColumnsNameData.Substring(0, idx - 1).Replace("\"", "");
                        if (!ColumnsName.Contains(ColumnsNameString))
                        {
                            ColumnsName.Add(ColumnsNameString);
                        }
                    }
                    catch (Exception ex)
                    {
                        throw new Exception(string.Format("Error Parsing Column Name : {0}", ColumnsNameData));
                    }
                }
                break;
            }
            foreach (string AddColumnName in ColumnsName)
            {

                DataRow nr = dt.NewRow();
                foreach (string rowData in RowData)
                {
                    try
                    {
                        int idx = rowData.IndexOf(":");
                        string RowColumns = rowData.Substring(0, idx - 1).Replace("\"", "");
                        string RowDataString = rowData.Substring(idx + 1).Replace("\"", "");
                        nr[RowColumns] = RowDataString;
                    }
                    catch (Exception ex)
                    {
                        continue;
                    }
                }
                dt.Rows.Add(nr);
            }
            return dt;
