A simple example of C timer timing updates

class Program 
    { 

        static void Main(string[] args) 
        { 
            //for (int i = 0; i < 100; i++) 
            //{ 

            //    SendMessage("13161626306", "13161626306"); 
            //} 
            System.Timers.Timer aTimer = new System.Timers.Timer(); 
            aTimer.Elapsed += new ElapsedEventHandler(aTimer_Elapsed); 
            //  Sets the time interval for the trigger time   Set this to 1 second (1000 milliseconds)  
            aTimer.Interval = 300;  // Set the time interval  
            aTimer.Enabled = true; 
            Console.WriteLine(" Press enter to end the program "); 
            Console.WriteLine("  Waiting for the program to execute... "); 
            Console.ReadLine(); 

    
            //SendMessage("13161626306", "13161626306"); 
        } 

        static void aTimer_Elapsed(object sender, ElapsedEventArgs e) 
        { 
            SendMessage("13161626306", "13161626306"); 
        } 

      
        private static void SendMessage(string PhoneNum, string Message) 
        { 
            try
            { 

  
                using (ServiceReference1.WcfServiceClient sum = new ConsoleApplication1.ServiceReference1.WcfServiceClient()) 
                { 
                   ServiceReference1.MessageOk ok = new ConsoleApplication1.ServiceReference1.MessageOk(); 

                        ok.Message = Message; 
                        ok.Phone = PhoneNum; 

                        ServiceReference1.MessageOk NewMessage = sum.Ok(ok); 

  
                        Console.WriteLine(NewMessage.Message); 
                        Console.WriteLine("22"); 

                    //Console.ReadLine(); 
                } 
            } 
            catch(Exception e) 
            { 
                Console.WriteLine(e.ToString()); 
                Console.ReadKey();
