Question

我有两个私有消息队列几乎同时出现同样的错误。

var msgLog = _msmqLogging.Receive(TimeSpan.FromSeconds(_timeoutSeconds));

if (msgLog != null) {
    var objLogEntry = msgLog.Body as LogEntry;

    _dsLog.Create(objLogEntry, _strConnection);
}

我得到的例外是

System.Messaging.MessageQueueException (0x80004005):  Operation was cancelled before it could be completed.
   at System.Messaging.MessageQueue.ReceiveCurrent(TimeSpan timeout, Int32 action, CursorHandle cursor, MessagePropertyFilter filter, MessageQueueTransaction internalTransaction, MessageQueueTransactionType transactionType)
   at System.Messaging.MessageQueue.Receive(TimeSpan timeout)

此代码在其他几台计算机上运行，但仅在一台特定计算机上运行。之后，MessageQueue似乎不起作用。从Thread内部调用该方法，并捕获异常。这就是为什么我怀疑这台机器上的MSMQ问题。我将尝试从Event-Log获取更多信息，只是想知道某人是否曾在过去遇到此行为。

在分析Windows事件日志之后，我在收到第一个异常之前立即发现了这些错误消息：

操作在完成之前被取消
