Hello,
Below is the code I have written to display the contents of an MSMQ queue. It works fine in case of winforms. But When i create a web application, Though the queue has some data, Nothing is displayed.
Can u help me..?
Thanks in advance.

using System;
using System.Collections.Generic;
using System.Linq;
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";
        }
       

    }

推荐答案

\\ 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 [ 1 024 ];
theMessage.BodyStream.Read（数据， 0 ， 1024 ）;
string strMessage = ASCIIEncoding.ASCII.GetString（data）;
Console.WriteLine（strMessage）;
}

if （NoMessage）
{
MessageBox.Show（ Message Queue为空）;

}
return 成功;
}


}

\\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"; } }

您想使用console.WriterLine（）在浏览器中写入？这是错误的！

使用Response.Write（）

Your want to use console.WriterLine() for writing in browser? it is wrong!
Use Response.Write()
