DbCommand ：执行超时已过期。完成操作之前已超时或服务器未响应。

问题：“Timeout 时间已到。在操作完成之前超时时间已过或服务器未响应。”的解决方法

在一个链接数据库的时候，老是出现超时的错误：执行超时已过期。完成操作之前已超时或服务器未响应。

就是给这个链接加上一个TimeOut的属性

 public static DataSet ExeQuery(string Cmd)
    {

        Database db = DatabaseFactory.CreateDatabase(connstring_TMS);
        DbConnection conn = db.CreateConnection();
        try
        {
            DbCommand comm = conn.CreateCommand();
            comm.CommandTimeout = 5000;//500秒，单位是秒
            conn.Open();
            comm.CommandText = Cmd;
            DbDataReader read = comm.ExecuteReader();
            return ConvertDataReaderToDataSet(read);
        }

        finally
        {
            conn.Close();
            conn = null;
        }
    }

  public static DataSet ConvertDataReaderToDataSet(DbDataReader reader)
     {
         DataSet dataSet = new DataSet();
         do
         {

             DataTable schemaTable = reader.GetSchemaTable();
             DataTable dataTable = new DataTable();
             if (schemaTable != null)

                     }
                     dataTable.Rows.Add(dataRow);
                 }
             }

             }
         }
         while (reader.NextResult());
         return dataSet;
