WS MQ - 从队列中删除消息

我正在使用 .net 框架来处理 ws 队列。是否可以从队列中移除/删除消息？

检索它会将其从队列中删除。如果您不想对检索到的消息执行任何操作，则可以将其丢弃。

    // Hit up MSMQ for list of new messages
    var queuedMessages = myMessageQueue.GetAllMessages();

    // Receive actual message to remove from the message queue
    var messages = new List<Message>();
    foreach (var queuedMessage in queuedMessages)
    {
        // Receive the message, which removes it from the queue. 
        try
        {
            messages.Add(this.messageQueue.ReceiveById(queuedMessage.Id));
        }
        // If it's already been removed, we skip over it.
        // TODO: Should try to catch only the "removed" exception
        catch (Exception)
        {
            continue;
        }
    }

返回消息；

Retrieving it will remove it from the queue. You can then discard the retrieved message if you don't want to do anything with it.

    // Hit up MSMQ for list of new messages
    var queuedMessages = myMessageQueue.GetAllMessages();

    // Receive actual message to remove from the message queue
    var messages = new List<Message>();
    foreach (var queuedMessage in queuedMessages)
    {
        // Receive the message, which removes it from the queue. 
        try
        {
            messages.Add(this.messageQueue.ReceiveById(queuedMessage.Id));
        }
        // If it's already been removed, we skip over it.
        // TODO: Should try to catch only the "removed" exception
        catch (Exception)
        {
            continue;
        }
    }

return messages;
