C#
DateTime dob = Convert.ToDateTime("18 Feb 1987");
            DateTime PresentYear = DateTime.Now;
            TimeSpan ts = PresentYear - dob;
            DateTime Age = DateTime.MinValue.AddDays(ts.Days);
            MessageBox.Show(string.Format(" {0} Years {1} Month {2} Days", Age.Year - 1, Age.Month - 1, Age.Day - 1));

Hi,
DateTime age = new DateTime(PresentYear.Subtract(dob).Ticks);
Should do the job. If you want to output a readable format,
textBox1.Text = age.Year.ToString() + " years " + age.Month.ToString() + " months " + age.Day.ToString() + " days ";
should be OK.

Regards.

Shows incorrect age.
C#
<pre>private void datediff(TextBox d1, Label lbl, TextBox d2 = null)
        {
            int days;
            int months;
            int years;
            string date2;
            if(d2 == null)
            {
                date2 = "31/08/2019";
            }
            else
            {
                date2 = d2.Text;
            }
            try
            {

I believe there are a couple of reasons why your solution is being downvoted.
1. The question was asked and answered 6.5 years ago and you haven't really added anything to existing solutions.
2. Your solution uses a Convert function which is probably why you added the unnecessary try-catch - Use TryParse functions instead.
3. If you test your code across a suitable range of dates you are going to find errors. If you want an "average" month, don't use the magic number (another reason to downvote) 30 … 30.5 will be more "accurate" and still wrong in some cases.

Reason why Solution 2 is getting lots of up-votes? It uses DateTime and Timespan. Granted it also uses a Convert function - however the value supplied is unambiguous.
I would recommend using AgeCalculator NuGet package. This library not only includes years, months, days and time components of the age but the calculation effected by the time component of the DateTime object. Optionally, it can be configured to treat Feb 29 of a leap year as Feb 28 of a non-leap year.

While I applaud your urge to help people, it's a good idea to stick to new questions, rather than 9 year old ones. After that amount of time, it's unlikely that the original poster is at all interested in the problem any more!
Answering old questions can be seen as rep-point hunting, which is a form of site abuse. The more trigger happy amongst us will start the process of banning you from the site if you aren't careful. Stick to new questions and you'll be fine.
