Question

Now the only conflict left is when two endDates (10,15 in code) min value comes against the same startDate(25).

solution: I want to take min value out among those two min. values given by conflicting endDate.

 public class DateController : Controller
    public ActionResult date()
    {
        int allDiff;
        List<int> list=new List<int>();
        int flag = 0;

        DateTime[] startDate = new DateTime[3];
        startDate[0] = new DateTime(2011, 11, 5);
        startDate[1] = new DateTime(2011, 11, 7);
        startDate[2] = new DateTime(2011, 11, 25);

        DateTime[] endDate = new DateTime[3];
        endDate[0] = new DateTime(2011, 11, 10);
        endDate[1] = new DateTime(2011, 11,15);
        endDate[2] = new DateTime(2011, 11, 30);
        DateTime Min= startDate.Min();
        DateTime Max = endDate.Max();

        TimeSpan span = Max - Min;
        int total = span.Days;
        ViewBag.globalTotal = total;


        foreach (DateTime e in endDate)
        {

            foreach (DateTime s in startDate)
            {
                if (s >= e)
                {
                    TimeSpan span1 = s - e;
                    allDiff = span1.Days;
                    list.Add(allDiff);
                    flag = 1;

                }
                else {
                    flag = 0;
                }

            }
            if (flag == 1)
            {
                int m = list.Min();
                ViewBag.dhiraj = m;
                total = total - m;
                list.Clear();
            }

        }
        ViewBag.Total = total;

        return View();
    }

Working code

 public ActionResult date()

        int output = 0;
        DateTime[] startDate = new DateTime[6];

        startDate[0] = new DateTime(2011, 11, 1);
