How to find days in year except Saturday and Sunday in C#

Before 2 years I have written a blog post to find Saturday and Sunday in given date range.  It has gain a lot of popularity and on that blog post one user ask about how we can find days in year except Saturday and Sunday in C#. This post is a in reply for that. Following is a code for that.

using System;

namespace DatimeApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            DateTime startDate = new DateTime(2013, 1, 1);
            DateTime endDate = new DateTime(2013, 12, 31);

            TimeSpan diff = endDate - startDate;
            int days = diff.Days;
            int j=0;
            for (var i = 0; i <= days; i++)
            {
                var testDate = startDate.AddDays(i);
                if (testDate.DayOfWeek != DayOfWeek.Saturday && testDate.DayOfWeek != DayOfWeek.Sunday)
                {
                    j = j + 1;
                    Console.WriteLine(testDate.ToShortDateString());
                }
            }
            Console.WriteLine(string.Format("Total Days:{0}",j));
            Console.ReadLine();
        }
    }
}

If you see above code,  Its very easy to find all days except Saturday and Sunday in a year. I have created two dates with Start date and end date and then I found a difference between those two days. And then in for loop I have checked whether they are weekdays then I have printed a date for that. I have calculated all days except Saturday and Sunday for year 2013. At the end I have printed total days also.

Once you run the code following is a output as expected.



That’s it. Hope you like it. Stay tuned for more…
