Question

on prod应用程序在从我的db上下文中检索数据时抛出一个ThreadAbortException，它大约是100万行数据表。我设置有意设置一个5小时的大CommandTimeOut，但即使我有一个system.web.httpException达到超时。通过记录，我可以获得此跟踪：

代码：

 public static DataTable GetSegmentDataTable(ICollection<long> idDrills, List<string> segmentColumnToDisplay)
        {
            var predicat = PredicateBuilder.True<DrillSegments>();
            Expression<Func<DrillSegments, bool>> exp = segments => idDrills.Contains(segments.DrillId);
            predicat = predicat.And(exp);

            using (var dqe = new DrillQuerierEntities { CommandTimeout = 18000})
            {

                try
                {
                    //Nom du forage
                    var result = dqe.DrillSegments.Include("DrillSegmentInfo.DrillSegmentInfoExtraData").AsExpandable().Where(predicat).OrderBy(x => x.SequenceNumber).ToList(); // first toList so querying db
                    var segmentDataTable = new DataTable("DrillSegments");

对这个奇怪的异常有什么看法吗？ Thx for advance

这是ASP.NET请求/页面超时。当达到超时时，ASP.NET将中止该线程。当工作进程关闭时，也可能由于新的代码部署而发生这种情况。增加请求超时。我认为该属性名为ScriptTimeout。
