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

This tutorial will show you how to delete 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 delete a simple directory to the disk, we will need to first import the System.IO namespace. The System.IO namespace contains the Delete() method that we will use to perform our delete with.

imports System.IO

We migrated our web sites to Server Intellect over one weekend and the setup was so smooth that we were up and running right away. They assisted us with everything we needed to do for all of our applications. With Server Intellect's help, we were able to avoid any headaches!

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

When the btnSubmit_Click() event fires it executes the Delete() method of the Directory namespace with the specified directory name in with the current directory (MapPath(".")) concatenating with our directory name and the boolean value of chkRecurse. This last argument specifies whether or not we would like to delete every subdirectory within our primary directory.

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

We chose Server Intellect for its dedicated servers, for our web hosting. They have managed to handle virtually everything for us, from start to finish. And their customer service is stellar.

We have one textbox, a Submit button, a label, and a checkbox 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> <asp:CheckBox ID="chkRecurse" runat="server" Text="Recursive Delete" /><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>

Yes, it is possible to find a good web host. Sometimes it takes a while. After trying several, we went with Server Intellect and have been very happy. They are the most professional, customer service friendly and technically knowledgeable host we've found so far.

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.Delete(MapPath(".") & "\" & txtDir.Text, chkRecurse.Checked) 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
