C# File Operations: Part 2

This article describes file operations.

Here we perform the three operations Delete, Copy & Move File.

First of all is the basic idea of this article..

OpenFileDialog ofd = new OpenFileDialog();

ofd.ShowDialog();

string myFileName = ofd.FileName;

What happens when the above code is used? Using the above code it will open a OpenFileDialog Box & from that the user can select a particular file.

Using the last line it will store the full path of selected file.

See below image:

FolderBrowserDialog fbd = new FolderBrowserDialog();

fbd.ShowDialog();

string destpath = fbd.SelectedPath;

Also using the above code it will open a "FolderBrowserDialog" box to select a path. Using the last line it will store the full path of the selected folder.

See the image below:

ofd.Dispose();

fbd.Dispose();

It will release all resources, which were used by "ofd" & "fbd".

ofd.SafeFileName;

It will give only filename with extension instead of full path.

System.IO.File.Delete(myFileName);

It will delete the particular given file from the given path.

System.IO.File.Copy(sourcepath, destpath + "\\" + ofd.SafeFileName);

It will copy the file from the source path to the destination path using the same name & if the name is already at destination path then it will give us a message.

System.IO.File.Move(sourcepath, destpath + "\\" + ofd.SafeFileName);

It will move the file from the source path to the destination path using the same name & if the name is already at destination path then it will give us a message.

Main 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;
using System.Data.SqlClient;

namespace MyBlog
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
btnDeleteFile.Click += new EventHandler(btnDeleteFile_Click);
btnCopyFile.Click += new EventHandler(btnCopyFile_Click);
btnMoveFile.Click += new EventHandler(btnMoveFile_Click);
}
private void btnDeleteFile_Click(object sender, EventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog();
ofd.ShowDialog();
string myFileName = ofd.FileName;
try
{
System.IO.File.Delete(myFileName);
MessageBox.Show("Selected File \"" + myFileName + "\" Deleted Successfully.");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString());
}
finally
{
ofd.Dispose();
}
}

private void btnCopyFile_Click(object sender, EventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog();
ofd.ShowDialog();
string sourcepath = ofd.FileName;

FolderBrowserDialog fbd = new FolderBrowserDialog();
fbd.ShowDialog();
string destpath = fbd.SelectedPath;
try
{
System.IO.File.Copy(sourcepath, destpath + "\\" + ofd.SafeFileName);
MessageBox.Show("File Copied Successfully.");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString());
}
finally
{
ofd.Dispose();
fbd.Dispose();
}
}

private void btnMoveFile_Click(object sender, EventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog();
ofd.ShowDialog();
string sourcepath = ofd.FileName;
