Introduction
In this article I will explain how to create and delete a directory or folder from your drive in ASP.NET using C#.When you are running a community website where the user posts articles, forum messages etc. When a user registers in a web site a folder can be created at run time, then when you upload or ask a query, the data can be automatically placed inside the user's own directory instead of the root or anywhere else. You must import the following namespace:
using System.IO;
Complete Program
Create_and_Remove_Directory.aspx.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO; // Add Namespace
public partial class Create_and_Remove_Directory : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void RadButton1_Click(object sender, EventArgs e)
{
string path = @"D:\" + txtname.Text; // Give the specific path
if (!(Directory.Exists(path)))
{
Directory.CreateDirectory(path);
Sucesslbl.Text = "Directory Created Successfully";
}
else
{
Sucesslbl.Text = "Already Directory Exits With Same Name";
}
}
protected void RadButton2_Click(object sender, EventArgs e)
{
string path = @"D:\" + deletetxt.Text;
if (Directory.Exists(path))
{
DeleteDirectory(path);
}
else
{
Deletelbl.Text = "Directory not exits";
}
}
private void DeleteDirectory(string path)
{
// Delete all files from the Directory
foreach (string filename in Directory.GetFiles(path))
{
File.Delete(filename);
}
// Check all child Directories and delete files
foreach (string subfolder in Directory.GetDirectories(path))
{
DeleteDirectory(subfolder);
}
Directory.Delete(path);
Deletelbl.Text = "Directory deleted successfully";
}
}
