hi

this is wt i hve done if i give directly the dob it is coming.but i want it as user enterable.
class Program
{
static void Main(string[] args)
{

DateTime dateOfBirth =Console.ReadKey() ;
Console.WriteLine("Enter The DOB:{0}", dateOfBirth);
//DateTime dateOfBirth = dateOfBirth.ToString();
//= new DateTime(1988, 3, 2);
int ageInYears = 0;
int ageInMonths = 0;
int ageInDays = 0;
CalculateAge(dateOfBirth,out ageInYears, out ageInMonths, out ageInDays);
Console.WriteLine("{0}, {1}, {2}", ageInYears, ageInMonths, ageInDays);
}

static void CalculateAge(DateTime DateOfBirth, out int NoOfYears, out int NoOfMonths, out int NoOfDays)
{
DateTime CurrentDate = DateTime.Now;
NoOfDays = CurrentDate.Day - DateOfBirth.Day;
NoOfMonths = CurrentDate.Month - DateOfBirth.Month;
NoOfYears = CurrentDate.Year - DateOfBirth.Year;
if (NoOfDays==0)
{
NoOfDays += DateTime.DaysInMonth(DateOfBirth.Year,DateOfBirth.Month);
NoOfMonths--;
}


if (NoOfMonths==0)
{
NoOfMonths += 12;
NoOfYears--;
}


}
}
}

You could use the following

// Get difference timespan

TimeSpan elapsed = currentDate.Subtract(dateOfBirth );


// Obtain the number of days since birth and similarly other fields

double daysAgo = elapsed.TotalDays;
