deleting a particular image from the folder which contains the images using c#

You can delete a file or a directory using the following code




  protected void lbtnremove1_Click(object sender, EventArgs e)
    {
        string imgname="Image1.jpg";
        try
        {
            File.Delete(Server.MapPath("../PropertyImages/12/" + imgname));
            File.Delete(Server.MapPath("../PropertyImages/12/"+ imgname));
        }
        catch (Exception ex)
        {
            lblMsg.Text = ex.Message.ToString();
        }

    }


U can either delete a root directory too by using the following code:


  protected void lbtnremove1_Click(object sender, EventArgs e)
    {
        string imgname="Image1.jpg";
        try
        {
            Directory.Delete(Server.MapPath("../PropertyImages/12));
            Directory.Delete(Server.MapPath("../PropertyImages/12));
        }
        catch (Exception ex)
        {
            lblMsg.Text = ex.Message.ToString();
        }

    }

Hi Pinky,
 
I tried my best to give you a descriptive answer. If you find it useful, please do accept my answer.
 
 

Let's say you added a form called Form1.
Then you dragged two buttons naemd button1(Open button) and button2(delete button).
You added events for the click events of those buttons as follows.
For button1 : button1_Click
For button2 : button2_Click

Then you added event for form load event.
Form1_Load

Then you dragged a listbox named listBox1.
Then you can use my code to do the rest.
 
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;
using System.IO;
namespace WindowsFormsApplication3
{
public partial class Form1 : Form
{
string path = "C:\\images";
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
try
{
//Save images
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Filter = "Image files (*.jpg)|*.jpg";
openFileDialog1.FilterIndex = 1;
openFileDialog1.RestoreDirectory = true;
string sourceFile = "";
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
sourceFile = openFileDialog1.FileName;
}
else
{
return;
}
string filename = Path.GetFileName(sourceFile);
//Let's say you want to add images to 'C:\images' folder.
string file = string.Format("{1}\\{0}", filename, path);
File.Copy(sourceFile, file);
listBox1.Items.Add(filename);
MessageBox.Show("Image saved");
}
catch (Exception ex)
{
MessageBox.Show(string.Format("Error! {0}", ex.Message));
}
}
private void button2_Click(object sender, EventArgs e)
{
try
{
if (listBox1.Items.Count == 0)
{
MessageBox.Show("No images");
return;
}
if (listBox1.SelectedIndex == -1)
{
MessageBox.Show("No Image selected");
return;
}
string filename = listBox1.SelectedItem.ToString();
string file = string.Format("{1}\\{0}", filename, path);
if (File.Exists(file))
{
File.Delete(file);
listBox1.Items.Remove(filename);
MessageBox.Show("Image deleted");
}
else
MessageBox.Show("File not found");
}
catch (Exception ex)
{
MessageBox.Show(string.Format("Error! {0}", ex.Message));
}
}
private void Form1_Load(object sender, EventArgs e)
{
try
{
string[] files = Directory.GetFiles(path);
foreach (string file in files)
{
string filename = Path.GetFileName(file);
listBox1.Items.Add(filename);
}
}
catch (Exception ex)
{
}
}
}
}
 
Please accept my answer if it helps you.

Hai..

here is the code for on button click it loads the list view item with the name of all photos in the specified folder..Don't forgot to add
using System.IO; in the begining .

 private void button1_Click(object sender, EventArgs e)
        {
            string[] fileEntries = Directory.GetFiles("E:\\Photos");
            foreach (string fileName in fileEntries)
            {
                // do something with fileName
                listBox1.Items.Add(fileName);
            }
        }

U can add in form load also..as u wish...and change the directory according to ur folder present..

If this wat u asked then reply i ll give the solution for delete files..
