Detect windows shutdown in consol application

[makdu]

as in previous post, i am using followwing code to detect the shutdown

protected override void WndProc(ref Message m)
        {
            if (m.Msg == WM_QUERYENDSESSION)
            {
                
                isShuttingDown = true;
            }
            base.WndProc(ref m);
        }

When the program is in the while loop, if a shut down comes, the break point put inside above fucntion is not hit. So what do event i have to put it in the loop so that when a shutdown messge happens, i get out of the loop

Did u mean put the code in do while loop?
like this ?

        do
                {
                    path = "d:\\madavas2.txt";
                    deletefiles(path);                                      
                    createfiles(path);                                      

                    readtext = readroutetable();                            
                    regMatch = "Active Routes:";
                    ActiveRoutes(regMatch, readtext);                       

                    Thread.Sleep(1000);                     
                    currentgateway();                                      


                    statuszain = comparerangeforz();                         
                    if (statuszain == true)
                    {
                        statusmada = comparerangeformada();                 

                    }
                    if (statusmada == true)
                    {
                        break;
                    }
                } while (statusmada == false);
