In this post I will explain about how to Calculate age from Date of Birth in C# with example.

Description:

In my previous posts I have explained various topics like Select random numbers items from list in C#, Sql Server Coalesce,Method Overloading, Abstract Class in C#

Now in this post, I will explain about how to Calculate age from Date of Birth in C# with appropriate example.To achieve this you need to make use of DateTime datatype and related calculation.

Now open Visual Studio , create Console Application and write below line of C#.Net in it.

using LibClass;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;

namespace DotNetByExample
{
    class Program
    {
        static void Main(string[] args)
        {
            DateTime dob = Convert.ToDateTime("1991/10/28");
            string fullAge = CalculateAgeFromDOB(dob);           

            Console.WriteLine(fullAge);            
            Console.ReadLine();
        }

        static string CalculateAgeFromDOB(DateTime p_Dob)
        {
            // Method to Calculate age from Date of Birth in C#
            DateTime Today = DateTime.Now;
            int Years = new DateTime(DateTime.Now.Subtract(p_Dob).Ticks).Year - 1;
            DateTime PastYearDate = p_Dob.AddYears(Years);
            int Months = 0;
            for (int i = 1; i <= 12; i++)
            {
                if (PastYearDate.AddMonths(i) == Today)
                {
                    Months = i;
                    break;
                }
                else if (PastYearDate.AddMonths(i) >= Today)
                {
                    Months = i - 1;
                    break;
                }
            }
            int Days = Today.Subtract(PastYearDate.AddMonths(Months)).Days;
            int Hours = Today.Subtract(PastYearDate).Hours;
            int Minutes = Today.Subtract(PastYearDate).Minutes;
            int Seconds = Today.Subtract(PastYearDate).Seconds;
            return String.Format("Age: {0} Year(s) {1} Month(s) {2} Day(s) {3} Hour(s) {4} Second(s)",
            Years, Months, Days, Hours, Seconds);
        }
    }
}

When you run above code snippet you will below output.
Age: 28 Year(s) 7 Month(s) 10 Day(s) 20 Hour(s) 19 Second(s)
