c# – 将有毒消息移动到处理队列

// path = "FormatName:DIRECT=OS:machine-nameprivate$queue-name";

var poisonQueue = new MessageQueue(path + ";poison");
var processingQueue = new MessageQueue(path);

foreach(var message in poisonQueue.GetAllMessages())
{
    processingQueue.Send(message);
}

var poisonCount = poisonQueue.GetAllMessages().Count();
var processingCount = processingQueue.GetAllMessage().Count();

不幸的是,Send()似乎没有做任何事情.调试器将计数显示为：

poisonCount: 6
processingCount: 0
