Is there a synchronization class that guarantee FIFO order in C#?

Question

What is it and how to use?

I need that as I have a timer that inserts into DB every second, and I have a shared resource between timer handler and the main thread. I

Answer 1

Actually the answers are good, but I solved the problem by removing the timer and run the method (timer-handler previously) into background thread as follows

    private void InsertBasicVaraibles()
    {
         int functionStopwatch = 0;
         while(true)
         {

           try
           {
             functionStopwatch = Environment.TickCount;
             DataTablesMutex.WaitOne();//mutex for my shared resources
             //insert into DB 
           }
           catch (Exception ex)
           {
             //Handle            
           }
           finally            
           {                
              DataTablesMutex.ReleaseMutex();
           }

           //simulate the timer tick value
           functionStopwatch = Environment.TickCount - functionStopwatch;
           int diff = INSERTION_PERIOD - functionStopwatch;
           int sleep = diff >= 0 ?  diff:0;
           Thread.Sleep(sleep);
        }
    }
