Introduction
Design simple age calculator , calculate remaining days from two dates. Suppose your Date of Birth is 19/mar/1987 and you want to calculate total days on till date. Here we take an simple demonstration of this type of application.Design
Step-1 : Add two DateTimerPicker and one button control on windows form.Step-2 : Take Two Datetime class instance, first for starting date and second for ending date.
Step-3 : Calulate difference between two dates using Timespan structure.
Step-4 : Using TotalDays property of TimeSpan structure you can calculate days.
Code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace datecalulator
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
DateTime dtstart = dateTimePicker1.Value;
DateTime enddate = dateTimePicker2.Value;
TimeSpan totaldays = enddate - dtstart;
int calculate =Convert .ToInt32 (totaldays.TotalDays);
MessageBox.Show(calculate.ToString()+" Days");
}
}
}
Code generate the following output
