通过Powershell在MSMQ上的消息数 [英] The number of messages on an MSMQ via Powershell

问题描述

我想提供一个队列路径并据此获取消息数量.关于如何做到这一点有什么建议吗?

I'd like to provide a queuepath and get the number of messages thereupon. Any advice on how this could be done?

So, I saw this: What can I do with C# and Powershell? and went here:http://jopinblog.wordpress.com/2008/03/12/counting-messages-in-an-msmq-messagequeue-from-c/

做到了

# Add the .NET assembly MSMQ to the environment.
[Reflection.Assembly]::LoadWithPartialName("System.Messaging")

# Create a new QueueSizer .NET class help to warp MSMQ calls.
$qsource = @"
public class QueueSizer
    {
        public static System.Messaging.Message PeekWithoutTimeout(System.Messaging.MessageQueue q, System.Messaging.Cursor cursor, System.Messaging.PeekAction action)
        {
            System.Messaging.Message ret = null;
            try
            {
                // Peek at the queue, but timeout in one clock tick.
                ret = q.Peek(new System.TimeSpan(1), cursor, action);
            }
            catch (System.Messaging.MessageQueueException mqe)
            {
                // Trap MSMQ exceptions but only ones relating to timeout. Bubble up any other MSMQ exceptions.
                if (!mqe.Message.ToLower().Contains("timeout"))
                {
                    throw;
                }
            }
            return ret;
        }

        // Main message counting method.
        public static int GetMessageCount(string queuepath)
        {
            // Get a specific MSMQ queue by name.
            System.Messaging.MessageQueue q = new System.Messaging.MessageQueue(queuepath);

            int count = 0;

            // Create a cursor to store the current position in the queue.
            System.Messaging.Cursor cursor = q.CreateCursor();

            // Have quick peak at the queue.
            System.Messaging.Message m = PeekWithoutTimeout(q, cursor, System.Messaging.PeekAction.Current);

            if (m != null)
            {
                count = 1;

                // Keep on iterating through the queue and keep count of the number of messages that are found.
                while ((m = PeekWithoutTimeout(q, cursor, System.Messaging.PeekAction.Next)) != null)
                {
                    count++;
                }
            }

            // Return the tally.
            return count;
        }
    }
"@

# Add the new QueueSizer class helper to the environment.
Add-Type -TypeDefinition $qsource -ReferencedAssemblies C:\Windows\assembly\GAC_MSIL\System.Messaging\2.0.0.0__b03f5f7f11d50a3a\System.Messaging.dll

# Call the helper and get the message count.
[QueueSizer]::GetMessageCount('mymachine\private$\myqueue');

它奏效了.
