This tutorial will show you how to delete a directory on the disk using ASP.NET 2.0 and C#.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.

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.

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:

The flow for the code behind page is as follows.
