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;

}

///
