Not sure to fully understand your expected output. How can the "last two week" can give you Nov 1 - 15? And you want a string as the output?

This is exactly what I can't understand. :0

Do you have any idea how to output ToString("MMM d ------and the end day" );

Considering that today we are Dec 2nd, what are you expecting to get as the output?

k, today is Dec 2 and I want to go 2 weeks back so the output I'm looking for to show is:
from the day Dec 2 to the previous two weeks. which actually should give me - Dec 2 - 19

this will give you a string of the last 2 weeks:

DateTime d = DateTime.Today;
string s = d.AddDays(-14).ToString("MMM d") + " - " + d.ToString("MMM d");
MessageBox.Show(s);

Dec 2 to 19  is not 2 weeks! and it is not previous, it is the future!

Consider this code:

DateTime d = DateTime.Today;
string prev = d.AddDays(-14).ToString("MMM d") + " - " + d.ToString("MMM d");
string next = d.ToString("MMM d") + " - " + d.AddDays(14).ToString("MMM d");
MessageBox.Show(prev + Environment.NewLine + next);

Thank you for your solution it works, but its not exactly what I want  as I did what you did in a different way:

Here is an example:

List<DateTime> LastFirstWeek = (from i in Enumerable.Range(0, 2) select DateTime.Today.AddDays(-(i * 6))).ToList();
 foreach (var t in LastFirstWeek)
            {
                var tf = new Timeframe();
                tf.firstWeek = t.ToString("MMM d");
                lst.Add(tf);

            }

What I'm trying to do is to return month, then the date of today and the date of 2 weeks before:
please look below:

This method then?

private void button1_Click(object sender, EventArgs e)
{
    DateTime d = DateTime.Today;
    MessageBox.Show(GetSpecialDateRange(d));
}

private string GetSpecialDateRange(DateTime pDate)
{
    if (pDate.Day >= 1 && pDate.Day <= 15)
    {
        return pDate.ToString("MMM") + " 1 - 15";
    }
    else
    {
        return pDate.ToString("MMM") + " 16 - " + DateTime.DaysInMonth(pDate.Year, pDate.Month);
    }
}

Thank you for your help.
It seems that you hard coded the days? I don't really get it.

That should be a dynamic data.

Actually you helped me a lot and thank you soo much. Now I understand this class much better.

I found exactlly what I need;

Here is my solution:

string datestr = dd.AddDays(-12).ToString("MMM d") + " " + (int)DateTime.Now.DayOfWeek;

Thanks for the great help.

Sorry if I wasn't clear enough.
