答えが見つかりました...コードの間違いは、間違ったリストにデータを追加していたことでした
私はこれが数回尋ねられたことを知っていますが、なぜこれが例外を与えるのか理解できません、どこかにロックがありませんか?
var sendsToday = new List<TSend>();
var threads = _maxNumberOfThreads;
if (threads <= 0)
threads = 1;
Parallel.ForEach(_subscribers,
new ParallelOptions { MaxDegreeOfParallelism = threads },
() => new ContentSendLocalStorage<TSend, TMedium>(_contentServices, _logService),
(subscriber, loopState, localStorage) =>
{
localStorage.LogService.Warning(string.Format("Choosing content for subscriber {0}", subscriber.SubscriberId));
foreach (var newsletterId in subscriber.SubscribedNewsletterIds)
{
localStorage.LogService.Warning(string.Format("Choosing content for newsletter {0}", newsletterId));
var clicks = StateBag.Get<LookupList>(StateKeys.LookupList).Clicks.Where(c => c.Subscriber.SubscriberId == subscriber.SubscriberId).Select(c => c.Content.ContentId).ToArray();
foreach (var contentService in _contentServices.Where(contentService => contentService.Contents.Count != 0))
{
subscriber.UrlsClicked = contentService.Contents
.Where(c => clicks.Contains(c.ContentId))
.GroupBy(g => g.Page.Url)
.ToDictionary(k => k.Key, v => 1);
var best = contentService.GetBestForSubscriber(subscriber, new TMedium { MediumId = int.Parse(newsletterId) });
if (best != null)
sendsToday.Add(best);
}
}
localStorage.LogService.Warning(string.Format("Done choosing content for subscriber {0}", subscriber.SubscriberId));
return localStorage;
},
finalStorage =>
{
lock (ContentSendLock)
{
sendsToday.AddRange(finalStorage.SubscriberSends);
}
});
私は以下の例外を受け取り続けます:
