Dear All

I have two dates ile Start Date and End Date.

I want to get the difference of the 2 dates in months.....How do we do it...

For eg.

Start Date = 01/11/2009
End Date: 01/01/2010;

The answer i want is 2 months

Help requested.

Thanks in advance

Convert both the dates to Datetime using

Convert.ToDateTime();
 

use TimeSpan to calculate the difference. Then you can get the number of days by Days property of TimeSpan object.

DateTime dt1 = new DateTime(2009,10,19), 
    dt2 = new DateTime(2009,11,19);
TimeSpan ts = dt2.Subtract(dt1);
int months = ts.Days / 30;

It isn't perfect, since not every month is 30 days, but it's close enough.

Adapt InsertAlias's code to us ts.TotalDays
TotalDays is the full timespan expressed as whole and fractional days

Good point, I used the wrong one.
