Select language as “visual c#”
and template as “Windows Forms Application”,give appropritate name,I give name as

66) Now design a
form as following.
77) Drag and drop FolderBrowserDiaglog and Timer control
in the form.they will appear at bottom .go to timer control property and set
Interval=3000.
88) Under the properties of next(>)
,previous(<) and Slide Show button
set Enable property is False.so by default they should be disable state .
99) Before you must need to import namespace System.IO
10)
Then write the
following code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO;
namespace SlideShowApp
{
public partial class Form1 : Form
{
string Dirpath;
int imgindex;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
for (int i = 1; i < 10; i++)
{
comboBox1.Items.Add(i);
comboBox1.SelectedIndex = 0;
}
}
private void button1_Click(object sender, EventArgs e)
{
DialogResult dr = folderBrowserDialog1.ShowDialog();
if (dr != DialogResult.Cancel)
{
listBox1.Items.Clear();
Dirpath = folderBrowserDialog1.SelectedPath;
string[] files = Directory.GetFiles(Dirpath, "*.Jpg");
foreach (string file in files)
{
int pos = file.LastIndexOf("||");
string FName =
file.Substring(pos + 1);
listBox1.Items.Add(FName);
}
listBox1.SelectedIndex =
imgindex = 0;
btnprev.Enabled = true;
btnnext.Enabled =
btnshow.Enabled = true;
}
}
private void btnshow_Click(object sender, EventArgs e)
{
if (btnshow.Text == "Slide
Show")
{
btnshow.Text = "stop show";
timer1.Interval = int.Parse(comboBox1.Text) * 1000;
timer1.Start();
}
else
{
timer1.Stop();
btnshow.Text = "Slide Show";
}
}
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
pictureBox1.ImageLocation =
listBox1.SelectedItem.ToString ();
//
pictureBox1.ImageLocation = Dirpath + "\\" + listBox1.SelectedItem;
}
private void btnprev_Click(object sender, EventArgs e)
{
if (imgindex > 0)
{
imgindex -= 1;
if(imgindex ==0)
{
btnprev .Enabled=false;
}
if (imgindex < listBox1.Items.Count - 1)
btnnext.Enabled = true;
listBox1.SelectedIndex =
imgindex;
}
}
private void btnnext_Click(object sender, EventArgs e)
{
if (imgindex < listBox1.Items.Count - 1)
{
imgindex += 1;
if (imgindex == listBox1.Items.Count - 1)
btnnext.Enabled = false;
if (imgindex > 0)
btnprev.Enabled = true;
listBox1.SelectedIndex =
imgindex;
}
}
private void timer1_Tick(object sender, EventArgs e)
{
btnnext.PerformClick();
}
}
}
11)now
