hi try below code

first write function 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";
       }


then in button click as below
private void bt_click(object sender, EventArgs e)
      {
          string _Age = CalculateYourAge(dtdob.Date);
         MessageBox.Show(_Age);
      }
here yellow one is your date and _Age is your result

1. {
2. DateTime date = DateTime.Now;
3. System.DateTime BirthDate = new System.DateTime(1991, 9, 11, 0, 0, 0);
4. System.TimeSpan diffResult = date.Subtract(BirthDate);
5. string TotalDays = diffResult.Days.ToString();
6. string Months = ((diffResult.Days) % 365).ToString();
7. string RemainingMonths = (Convert.ToInt32(Months) / 31).ToString();
8. string RemainginYears = ((diffResult.Days) / 365).ToString();
9. string RemainingDays = (Convert.ToInt32(Months) % 31).ToString();
10. MessageBox.Show(RemainginYears + "-" + RemainingMonths + "-" + RemainingDays);
11. }
