cannot post to MSMQ from dotnet code   

I am not able to post a simple message locally to my local MSMQ through this 
code although I can post to the same queue using some demo code.

My code is



using System;
using System.Collections.Generic;
using System.Xml;
using System.IO;
using System.Text;
using System.Reflection;
using System.Messaging;

namespace WindowsApplication1
{
    static class test
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            

            string oobject;
            Message mymessage = new Message();
            MessageQueue myMSMQueue = new MessageQueue();
            MessageQueueTransaction myquetrans = new 
MessageQueueTransaction();
            ActiveXMessageFormatter xmlmessageformat = new 
ActiveXMessageFormatter();
            myMSMQueue.Path = (@".\private$\incomingqueue");


            oobject = "message sent";
            mymessage.Label = "testx";
            mymessage.Body = oobject;
            try
            {
                myMSMQueue.Send(oobject);
            }
            catch (MessageQueueException ex)
            {
                Console.WriteLine("message " + ex.Message);
                Console.WriteLine("message " + ex.Source);
                Console.WriteLine("message " + ex.InnerException.Message);
            }

            myMSMQueue.Close();

                    }
    }
}
