public delegate int DelegateClass(out DateTime start,out DateTime stop);

public class Starter {

    public static void Main() {
        DelegateClass del = MethodA;
        DateTime start;
        DateTime stop;
        IAsyncResult ar = del.BeginInvoke(out start, out stop,null, null);
        ar.AsyncWaitHandle.WaitOne();

        int elapse = del.EndInvoke(out start, out stop, ar);
        Console.WriteLine("Start time: {0}", start.ToLongTimeString());
        Console.WriteLine("Stop time: {0}", stop.ToLongTimeString());
        Console.WriteLine("Elapse time: {0} seconds",elapse);
