Add Business Days to a date

Question

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); } } } EDITED: To simplify switch statement
