Add Business Days to a date

Hi,

I tried searching this and did not get exactly what I needed. I want to add 2 Business days to a given day. If it is Monday on 09/24/2007 10:00:00 then the code has to add 2 days to become 09/26/2007 10:00:00.

However, if it is Friday on 09/28/2007 10:00:00, then the code has to add 2 business days to become 10/02/2007 10:00:00.

Please help.

Thanks,

Prasanna.

This should do it:

using System;

class Program
{
    static void Main()
    {
       string startDate1 = "09/24/2007 10:00:00";
       string endDate1 = AddTwoBusinessDays(startDate1);
       Console.WriteLine("{0} plus 2 business days is {1}", startDate1, endDate1);
       string startDate2 = "09/28/2007 10:00:00";
       string endDate2 = AddTwoBusinessDays(startDate2);
       Console.WriteLine("{0} plus 2 business days is {1}", startDate2, endDate2);
       Console.ReadKey();
    }

    public static string AddTwoBusinessDays(string startDate)
    {
       string format = "MM/dd/yyyy HH:mm:ss";
       DateTime dt = DateTime.ParseExact(startDate, format, null);
       switch (dt.DayOfWeek)
       {
          case DayOfWeek.Thursday:
          case DayOfWeek.Friday:
              return dt.AddDays(4).ToString(format);
          case DayOfWeek.Saturday:
              return dt.AddDays(3).ToString(format);
          default:
              return dt.AddDays(2).ToString(format);
       }
    }
}
