Hi Akshay,
Please see the below code. It will return you the date difference in the same format you want:
DateDifference dateDifference = new DateDifference(this.dateTimeTo.Value, this.dateTimeFrom.Value);
string dateDifferenceResult = dateDifference.ToString();
Implementation of above class(DateDifference.cs) :
public class DateDifference
{
///
/// defining Number of days in month; index 0=> january and 11=> December
/// february contain either 28 or 29 days, that's why here value is -1
/// which wil be calculate later.
///
private int[] monthDay = new int[12] { 31, -1, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 };
///
/// contain from date
///
private DateTime fromDate;
///
/// contain To Date
///
private DateTime toDate;
///
/// this three variable for output representation..
///
private int year;
private int month;
private int day;
public DateDifference(DateTime d1, DateTime d2)
{
int increment;
if (d1 > d2)
{
this.fromDate = d2;
this.toDate = d1;
}
else
{
this.fromDate = d1;
this.toDate = d2;
}
///
/// Day Calculation
///
increment = 0;
if (this.fromDate.Day > this.toDate.Day)
{
increment = this.monthDay[this.fromDate.Month - 1];
}
/// if it is february month
/// if it's to day is less then from day
if (increment == -1)
{
if (DateTime.IsLeapYear(this.fromDate.Year))
{
// leap year february contain 29 days
increment = 29;
}
else
{
increment = 28;
}
}
if (increment != 0)
{
day = (this.toDate.Day increment) - this.fromDate.Day;
increment = 1;
}
else
{
day = this.toDate.Day - this.fromDate.Day;
}
///
///month calculation
///
if ((this.fromDate.Month increment) > this.toDate.Month)
{
this.month = (this.toDate.Month 12) - (this.fromDate.Month increment);
increment = 1;
}
else
{
this.month = (this.toDate.Month) - (this.fromDate.Month increment);
increment = 0;
}
///
/// year calculation
///
this.year = this.toDate.Year - (this.fromDate.Year increment);
}
public override string ToString()
{
//return base.ToString();
return this.year " Year(s), " this.month " month(s), " this.day " day(s)";
}

{
