Can u help me..?

using System.Web;
using System.Web.Services;
using System.Messaging;
using System.Text;
using System.Windows.Forms;

namespace MSMQWebService
{
    /// <summary>
    /// Summary description for Service1
    /// </summary>

    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]

    public class Service1 : System.Web.Services.WebService
    {
        string QueueName = ".\\Private$\\q1";


        
        [WebMethod]
        public string DisplayMessage()
        {
            bool NoMessage = true;
           MessageQueue Q1 = new MessageQueue(QueueName);
            System.Messaging.Message[] AllMessages = Q1.GetAllMessages();
            foreach (System.Messaging.Message theMessage in AllMessages)
            {
                NoMessage = false;
                byte[] data = new byte[1024];
                theMessage.BodyStream.Read(data, 0, 1024);
                string strMessage = ASCIIEncoding.ASCII.GetString(data);
                Console.WriteLine(strMessage);    
           }
          
           if (NoMessage)
            {
                MessageBox.Show("Message Queue is Empty");

            }
           return "Success";
        }
       

    }
