Increment date

Thanks for the reply,

can you do me one more favor please. If i need to convert the enddate into MM-dd-yyyy format and remove the time from it. How can i do that?

Your requirement is not very clear...do you mean to update end date by "1 month" or "15 days" depending upon the condition or do you want to update by 1 month and 15 days (which would be 45 days if the month has 30 days)? This is not clear...I mean do you want a conditional update for either 1 month or 15 days or just 1 update?  If it's only 1 update here's the code:

Assuming you have converted your date from string enddate to a DateTime value dt:

dt = dt.AddMonths(1); then followed by
dt = dt.AddDays(15);
