Delete a file in a directory using System.IO

[Arg81]

Hi Guys,

I can do the basic file delete, but I need to work out how to delete a file with a changing part of the filename.

My app creates a PDF called DCList - date_of_creation.pdf i.e. DCList - 01 February 2008.pdf

Any changes made to the data in the database automatically forces the user to re-create this file.
If she edits / adds data on the same date, the file simply overwrites itself.

The bit I'm stumped at is trying to delete the previous day(s) pdf file. There should only ever be 1 PDF file in this folder, so I don't need to delete a lot, just only the one.

Is this something simple to do, and I've just missed the concept??

theDate.AddDays(-1) gets you the date of the previous day.

so something like;

Dim d As Date = Today
        Dim strToDelete As String = strDirectory & "DCList - " & d.AddDays(-1).ToLongDateString & ".pdf"
        If File.Exists(strToDelete) Then File.Delete(strToDelete)

Just edited for my date noobness
