Creating a directory using ASP.NET 2.0 and VB .NET

This tutorial will show you how to create a directory on the disk using ASP.NET 2.0 and VB.NET

The .NET Framework offers a number of types that makes accessing resources on filesystems easy to use.

To write a simple directory to the disk, we will need to first import the System.IO namespace. The System.IO namespace contains the CreateDirectory() method that we will use to create our directory.

Imports System.IO

We are using Server Intellect and have found that by far, they are the most friendly, responsive, and knowledgeable support team we've ever dealt with!

We'll put our code in the btnSubmit_Click() event.

When the btnSubmit_Click() event fires it executes the CreateDirectory() method with the specified directory name in txtDir.

Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Try Directory.CreateDirectory(MapPath(".") & "\" & txtDir.Text) Catch ex As Exception lblStatus.Text = ex.Message End Try End Sub

We have one textbox, a Submit button, and a label on the front end for user interaction. The front end .aspx page looks something like this:

<table width="600" border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#cccccc"> <tr> <td width="100" align="right" bgcolor="#eeeeee" class="header1"> Directory to Create:</td> <td align="center" bgcolor="#FFFFFF"> <asp:TextBox ID="txtDir" runat="server"></asp:TextBox><br /> <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" /><br /> &nbsp; <asp:label ID="lblStatus" runat="server"></asp:label></td> </tr> </table>

The flow for the code behind page is as follows.

Imports System.IO Partial Class _Default Inherits System.Web.UI.Page Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Try Directory.CreateDirectory(MapPath(".") & "\" & txtDir.Text) Catch ex As Exception lblStatus.Text = ex.Message End Try End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load End Sub End Class
