Introduction:
Here I will explain how to create directory or folder, delete directory or
folder in asp.net using C#
and VB.NET or
Description:
In previous articles I explained Delete files from uploaded folder in asp.net, Check username availability with progressbar, Richtextbox example in asp.net, Asp.net Interview questions, Joins in SQL Server, Highlight Gridview records based on search and many
articles relating to Gridview,
SQL ,jQuery,asp.net,
C#,VB.NET.
Now I will explain how to create, delete directory or folder in asp.net
using C# and VB.NET.
To create or delete directory/folder we need to write
the code like as shown below
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Create or Delete
Directory/floder in asp.net</title>
</head>
<body>
<form id="form1"
runat="server">
<table>
<tr>
<td><b>Enter File Name to
Create:</b></td>
<td><asp:TextBox ID="txtName"
runat="server"
/></td>
<td> <asp:Button ID="btnCreate"
runat="server"
Text="Create
Directory" Font-Bold="true" onclick="btnCreate_Click" /> </td>
</tr>
<tr>
<td><b>Enter File Name to
Delete:</b></td>
<td><asp:TextBox ID="txtdltName"
runat="server"
/></td>
<td> <asp:Button ID="btnDelete"
runat="server"
Text="Delete
Directory" Font-Bold="true" onclick="btnDelete_Click" /> </td>
</tr>
<tr><td colspan="3"><asp:Label ID="lblResult" runat="server" ForeColor="Red" /> </td></tr>
</table>
</form>
</body>
</html>

Now in code behind add the
following namespaces
C#
Code
using System;
using System.IO;
|
Once you add namespaces write
the following code in code behind
// Create new directory
protected void btnCreate_Click(object
sender, EventArgs e)
{
string strpath = @"D:\" + txtName.Text;
//Condition to check if any directory exists with same
name
if (!(Directory.Exists(strpath)))
{
Directory.CreateDirectory(strpath);
lblResult.Text = "Directory
Created";
}
else
{
lblResult.Text = "Already
Directory Exists with the same name";
}
}
// Delete direcoty or folder
protected void btnDelete_Click(object
sender, EventArgs e)
{
string strpath = @"D:\" + txtdltName.Text;
if (Directory.Exists(strpath))
{
RemoveDirectories(strpath);
}
else
{
lblResult.Text = "Directory not
exists";
}
}
private void RemoveDirectories(string
strpath)
{
//This condition is used to delete all files from the
Directory
foreach (string file in Directory.GetFiles(strpath))
{
File.Delete(file);
}
//This condition is used to check all child Directories
and delete files
foreach (string subfolder in
Directory.GetDirectories(strpath))
{
RemoveDirectories(subfolder);
}
Directory.Delete(strpath);
lblResult.Text = "Directory
deleted";
}

VB.NET
Code
Imports System.IO
Partial Class VBCode
Inherits System.Web.UI.Page
Protected Sub Page_Load(sender As
Object, e As EventArgs)
End Sub
' Create new directory
Protected Sub btnCreate_Click(sender As
Object, e As EventArgs)
Dim strpath As String = "D:\" + txtName.Text
'Condition to check if any directory exists with same
name
If Not (Directory.Exists(strpath)) Then
Directory.CreateDirectory(strpath)
lblResult.Text = "Directory
Created"
Else
lblResult.Text = "Already
Directory Exists with the same name"
End If
End Sub
' Delete direcoty or folder
Protected Sub btnDelete_Click(sender As
Object, e As EventArgs)
Dim strpath As String = "D:\" + txtdltName.Text
If Directory.Exists(strpath)
Then
RemoveDirectories(strpath)
Else
lblResult.Text = "Directory not
exists"
End If
End Sub
Private Sub RemoveDirectories(strpath As String)
'This condition is used to delete all files from the
Directory
For Each file1 As String In Directory.GetFiles(strpath)
File.Delete(file1)
Next
'This condition is used to check all child Directories
and delete files
For Each subfolder As String In Directory.GetDirectories(strpath)
RemoveDirectories(subfolder)
Next
Directory.Delete(strpath)
lblResult.Text = "Directory
deleted"
End Sub
End Class

If you demo with 3 tiers is very good, because all application often use 3 tiers.
