Hi Thirunavukkarsu,

Try this...

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 Total_days_from_two_dates_csharp
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btn_total_Click(object sender, EventArgs e)
        {
            int Totaldays = duration(textBox1.Text, textBox2.Text);

            label1.Text = Convert.ToString(Totaldays);
        }
        public int duration(string startdate, string enddate)
        {

            DateTime dt1 = DateTime.Parse(Convert.ToDateTime(textBox1.Text).ToString("dd/MM/yyyy"));
            DateTime dt2 = DateTime.Parse(Convert.ToDateTime(textBox2.Text).ToString("dd/MM/yyyy"));
            TimeSpan ts = dt2.Subtract(dt1);
            int days = ts.Days;
            return days;
