I want list file directory in treeview control with checkboxes .Tnen perform delete function to delete selectef file or folder in c sharp

Hi ankita!

You may use following code to list files and folders to treeview control...

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 nListingFoldersToTreeView

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

            LoadFoldersInTreeView(treeView1);

        }

        void LoadFoldersInTreeView(TreeView treeName)

        {

            treeName.BeginUpdate();

            treeName.Nodes.Add("Desktop");

            treeName.Nodes[0].Nodes.Add("My Documents");

            treeName.Nodes[0].Nodes.Add("My Computer");

            treeName.Nodes[0].Nodes.Add("My Network places");

            DirectoryInfo dirInfo = new DirectoryInfo(@"C:\");

            TreeNode node = new TreeNode();

            GetFiles(dirInfo, node);

            treeName.EndUpdate();

        }

        void GetFiles(DirectoryInfo d, TreeNode node)

        {

            DirectoryInfo[] dInfo = d.GetDirectories();

            if (dInfo.Length > 0)

            {

                TreeNode treeNode = new TreeNode();

                foreach (DirectoryInfo driSub in dInfo)

                {

                    treeNode = node.Nodes.Add(driSub.Name);

                    // once working I will make it recursive           

                    //GetFiles(driSub, treeNode);

                }

            }

        }

    }

}

You can use following snippet:

// Simple synchronous file copy operations with no user interface.
// To run this sample, first create the following directories and files:
// C:\Users\Public\TestFolder
// C:\Users\Public\TestFolder\test.txt
// C:\Users\Public\TestFolder\SubDir\test.txt
public class SimpleFileCopy
{
    static void Main()
    {
        string fileName = "test.txt";
        string sourcePath = @"C:\Users\Public\TestFolder";
        string targetPath =  @"C:\Users\Public\TestFolder\SubDir";

        // Use Path class to manipulate file and directory paths.
        string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
        string destFile = System.IO.Path.Combine(targetPath, fileName);

        // To copy a folder's contents to a new location:
        // Create a new target folder, if necessary.
        if (!System.IO.Directory.Exists(targetPath))
        {
            System.IO.Directory.CreateDirectory(targetPath);
        }

        // To copy a file to another location and
        // overwrite the destination file if it already exists.
        System.IO.File.Copy(sourceFile, destFile, true);

        // To copy all the files in one directory to another directory.
        // Get the files in the source folder. (To recursively iterate through
        // all subfolders under the current directory, see
        // "How to: Iterate Through a Directory Tree.")
        // Note: Check for target path was performed previously
        //       in this code example.
        if (System.IO.Directory.Exists(sourcePath))
        {
            string[] files = System.IO.Directory.GetFiles(sourcePath);

            // Copy the files and overwrite destination files if they already exist.
            foreach (string s in files)
            {
                // Use static Path methods to extract only the file name from the path.
                fileName = System.IO.Path.GetFileName(s);
                destFile = System.IO.Path.Combine(targetPath, fileName);
                System.IO.File.Copy(s, destFile, true);
            }
        }
        else
        {
            Console.WriteLine("Source path does not exist!");
        }

        // Keep console window open in debug mode.
        Console.WriteLine("Press any key to exit.");
        Console.ReadKey();
    }
}


Thanking you,
