Hi VikasKumar,

Try this code, But this is sample code, you can modify the code as per your requirement and you can implement much better compare this code...
public void Display()
       {
           DateTime date = DateTime.Now;
           System.DateTime BirthDate = new System.DateTime(1991, 9, 11, 0, 0, 0);
           System.TimeSpan diffResult = date.Subtract(BirthDate);
           string TotalDays = diffResult.Days.ToString();
           string Months = ((diffResult.Days) % 365).ToString();
           string RemainingMonths = (Convert.ToInt32(Months) / 31).ToString();
           string RemainginYears = ((diffResult.Days) / 365).ToString();
           string RemainingDays = (Convert.ToInt32(Months) % 31).ToString();
           MessageBox.Show(RemainginYears + "-" + RemainingMonths + "-" + RemainingDays);
       }

1. static void CalculateAge()
2. {
3. DateTime dateOfBirth;
4. DateTime.TryParse("02/18/2008", out dateOfBirth);
5. DateTime currentDate = DateTime.Now;
7. TimeSpan difference = currentDate.Subtract(dateOfBirth);
9. // This is to convert the timespan to datetime object
10. DateTime age = DateTime.MinValue + difference;
12. // Min value is 01/01/0001
13. // Actual age is say 24 yrs, 9 months and 3 days represented as timespan
14. // Min Valye + actual age = 25 yrs , 10 months and 4 days.
15. // subtract our addition or 1 on all components to get the actual date.
17. int ageInYears = age.Year - 1;
18. int ageInMonths = age.Month - 1;
19. int ageInDays = age.Day - 1;
21. Console.WriteLine("{0}, {1}, {2}", ageInYears, ageInMonths, ageInDays);
22. }

try as follows

create one funcction in c# as below

public static string CalculateYourAge(DateTime Dob)
{
DateTime Now = DateTime.Now;
int _Years = new DateTime(DateTime.Now.Subtract(Dob).Ticks).Year - 1;
DateTime _DOBDateNow = Dob.AddYears(_Years);
int _Months = 0;
for (int i = 1; i <= 12; i++)
{
if (_DOBDateNow.AddMonths(i) == Now)
{
_Months = i;
break;
}
else if (_DOBDateNow.AddMonths(i) >= Now)
{
_Months = i - 1;
break;
}
}
int Days = Now.Subtract(_DOBDateNow.AddMonths(_Months)).Days;
return $"Age is {_Years} Years {_Months} Months {Days} Days";
}

in button click call this function

private void bt_click(object sender, EventArgs e)
{
string _Age = CalculateYourAge(dtdob.Value);
lblAge.Text = _Age;
}

Hi Dude,

Please try this below code it will work:
using System;
public class Age
{
public int Years;
public int Months;
public int Days;
public Age(DateTime Bday)
{
this.Count(Bday);
}
public Age(DateTime Bday, DateTime Cday)
{
this.Count(Bday, Cday);
}
public Age Count(DateTime Bday)
{
return this.Count(Bday, DateTime.Today);
}
public Age Count(DateTime Bday, DateTime Cday)
{
if ((Cday.Year - Bday.Year) > 0 ||
(((Cday.Year - Bday.Year) == 0) && ((Bday.Month < Cday.Month) ||
((Bday.Month == Cday.Month) && (Bday.Day <= Cday.Day)))))
{
int DaysInBdayMonth = DateTime.DaysInMonth(Bday.Year, Bday.Month);
int DaysRemain = Cday.Day + (DaysInBdayMonth - Bday.Day);
if (Cday.Month > Bday.Month)
{
this.Years = Cday.Year - Bday.Year;
this.Months = Cday.Month - (Bday.Month + 1) + Math.Abs(DaysRemain / DaysInBdayMonth);
this.Days = (DaysRemain % DaysInBdayMonth + DaysInBdayMonth) % DaysInBdayMonth;
}
else if (Cday.Month == Bday.Month)
{
if (Cday.Day >= Bday.Day)
{
this.Years = Cday.Year - Bday.Year;
this.Months = 0;
this.Days = Cday.Day - Bday.Day;
}
else
{
this.Years = (Cday.Year - 1) - Bday.Year;
this.Months = 11;
this.Days = DateTime.DaysInMonth(Bday.Year, Bday.Month) - (Bday.Day - Cday.Day);
}
}
else
{
this.Years = (Cday.Year - 1) - Bday.Year;
this.Months = Cday.Month + (11 - Bday.Month) + Math.Abs(DaysRemain / DaysInBdayMonth);
this.Days = (DaysRemain % DaysInBdayMonth + DaysInBdayMonth) % DaysInBdayMonth;
}
}
else
{
throw new ArgumentException("Birthday date must be earlier than current date");
}
return this;
}
}
/**
* Usage example:
* ==============
* DateTime bday = new DateTime(1987, 11, 27);
* DateTime cday = DateTime.Today;
* Age age = new Age(bday, cday);
* Console.WriteLine("It's been {0} years, {1} months, and {2} days since your birthday", age.Year, age.Month, age.Day);

Try like below:

String sDate = DateTime.Now.ToString(); // You will take from UI
DateTime datevalue = (Convert.ToDateTime(sDate.ToString()));
String dy = datevalue.Day.ToString();
String mn = datevalue.Month.ToString();
String yy = datevalue.Year.ToString();
