 public string suggestionlist = ""; string querystring = "select * newmedicinemaster";             using (sqlconnection con = new sqlconnection(system.web.configuration.webconfigurationmanager.connectionstrings["hospitalconnection"].connectionstring))             {                  using (sqlcommand command = new sqlcommand(querystring, con))                 {                      con.open();                      using (sqldatareader reader = command.executereader())                     {                          while (reader.read())                         {                              if (string.isnullorempty(suggestionlist))                             {                                 suggestionlist += "\"" + reader["medname"].tostring() + "-" + reader["medid"].tostring() + "\"";                             }                             else                             {                                 suggestionlist += ", \"" + reader["medname"].tostring() + "-" + reader["medid"].tostring() + "\"";                             }                         }                     }                 }             }
