c # — ошибка исправления: System.AccessViolationException
У меня есть приложение быстрого исправления .net. я использую .net / c ++ версия быстрого исправления
Иногда мое приложение выдает эту ошибку, и я не могу поймать ее с помощью блока try catch.
Длина сообщений об исправлении составляет около 3000. Я не получаю эту ошибку каждый раз.

Решение
это выглядит связанным.
Речь идет о состоянии гонки в объекте Group, который собирает мусор до того, как на него ссылаются.
Вы хотите что-то вроде gcnew за: .Чистая сборка мусора
Другие решения
Я исправил эту проблему, сделал список запросов.
Пример:
public void RequisitarMarketData(List<String> _lstAtivo, String _mercado, String _id, SessionID sessionId)
{
QuickFix44.MarketDataRequest _marketDataRequest = new QuickFix44.MarketDataRequest();
_marketDataRequest.set(new MDReqID(_id));
_marketDataRequest.set(new SubscriptionRequestType('1'));var anoMDEntryTypes = new QuickFix44.MarketDataRequest.NoMDEntryTypes();
var amdEntryType_bid = new MDEntryType('2');anoMDEntryTypes.set(amdEntryType_bid);
_marketDataRequest.addGroup(anoMDEntryTypes);
_marketDataRequest.set(new MarketDepth(0));
foreach (String _ativo in _lstAtivo)
{
var relatedSymbol = new QuickFix44.MarketDataRequest.NoRelatedSym();
relatedSymbol.set(new Symbol(_ativo));
_marketDataRequest.addGroup(relatedSymbol);
}var relatedSymbola = new QuickFix44.MarketDataRequest.NoRelatedSym();
relatedSymbola.set(new SecurityExchange(_mercado));
_marketDataRequest.addGroup(relatedSymbola);
//Send message
Session.sendToTarget(_marketDataRequest, sessionId);
