NHibernate multithreading issue (多线程问题)

      int limitTimes;
            int.TryParse(ConfigurationManager.AppSettings["LimitTimes"], out limitTimes);
            var redoPurchaseEntityList =
              this.redoPurchaseEntityRepository.FindByExpression(p => p.SendNumber < limitTimes).ToList();
            if (redoPurchaseEntityList.Count == 0)
            {
                return;
            }
            Parallel.ForEach(
                this.redoPurchaseProvideList,
                redoPurchase =>
                {
                    var task = new Task(() => redoPurchase.RedoPurchase(redoPurchaseEntityList));
                    task.StartAndContinueWith();
                });

上面代码主要是从数据库中查询出一个表的list集合然后多线程并行查找同一个list，会得到一个错误信息

There is already an open DataReader associated with this Command which must be closed first.
at System.Data.SqlClient.SqlInternalConnectionTds.ValidateConnectionForExecute(SqlCommand command)

因为用的是一个session,导致读取错误多线程不可互用同一个session.
