C＃“已经有一个与此Connection关联的开放DataReader，必须先关闭它

Question

  

可能重复：
  MultiThreading error: There is already an open DataReader associated with this Connection which must be closed first

我不知道为什么我仍然遇到这个问题，这是我的下面的代码，感谢任何帮助。

public static DataTable DTTable(string mysqlQuery, string queryName)
        {
            lock (_object)
            {
                DataTable DTTableTable = new DataTable();
                try
                {
                    using (MySqlDataAdapter DataDTTables = new MySqlDataAdapter(mysqlQuery, MySQLProcessing.MySQLStatic.Connection))
                    {
                        using (DataTable DataDTTablesDT = new DataTable())
                        {
                            DataDTTables.SelectCommand.CommandTimeout = 240000;
                            DataDTTables.Fill(DataDTTablesDT);
                            DTTableTable = DataDTTablesDT;
                            DataDTTables.Dispose();
                        }
                    }

                }
                catch (Exception ex)
                {

                    GenericLogging("Failed MySQLquery: " + ex.Message.ToString(), "MySQLProcessor", "DTTable", "", "MysqlError", "", queryName, mysqlQuery);

                }
                return DTTableTable;
            }
        }
