ASP.NET Get future 6 months

Question

So what I am looking to do is to get future six months in a dropdown box and I was trying something like

        public List<String> GetTrainingDates()
    {
        var monthList = new List<String>();
        var currentMonth = DateTime.Now.Month;
        for(var i = currentMonth; i <= currentMonth + 6; i++)
        {
            monthList.Add(CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(i));
        }
        return monthList;
    }

But ofcourse this goes greater than 12, so would have to restart at 12 and then start from 1 again.

Just wondering if anybody has a good idea how to do this ?

Just use the % modulus operator:

monthList.Add(CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(
               ((i - 1) % 12) + 1));

        {
            var monthList = new List<String>();
            var currentDate = DateTime.Now();
            for(var i = 0; i <= 6; i++)
            {              
                monthList.Add(CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(currentDate.AddMonths(i).Month));
            }
            return monthList;
        }

This will not get the _next_ 6 months. Just January to June. – Oded Aug 01 '12 at 15:48
@Oded Please explain? I don't agree. – Curtis Aug 01 '12 at 15:48
Apologies - missed the use of `DateTime.Now.AddMonths` – Oded Aug 01 '12 at 15:56

Use the .AddMonths function of the DateTime class...

public List<String> GetTrainingDates()
{
    var monthList = new List<String>();
    var month;
    for(var i = 1; i <= 6; i++)
    {
       month = DateTime.Now.AddMonths(i).Month;
       monthList.Add(CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(month));
    }
    return monthList;
}

Simply, you can use LINQ expression with Range.....

 List<string> listMonth = Enumerable.Range(1, 6).ToList()
                             .Select(i => CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(DateTime.Now.AddMonths(i).Month))
                             .ToList();

ASP.NET Get future 6 months
