How to Delete File(s) Listed in a ListBox (not ListBox1.Clear)

-1

I am working on a program that can create and delete files within it. The files are located (for example) at: C:FilesForProgramXXXXXXX The Xs are for the name of the program.
Say, for example that I want to delete the following files:

C:FilesForProgramXXXXXXXdeleteme.txt

C:FilesForProgramXXXXXXXdeleteme2.exe

C:FilesForProgramXXXXXXXTrashineedtobedeleted.txt

I have no way to do that. I can create the files, but not delete them. Here is a example of what the code I am currently using:

    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

    If ListBox3.Items.Count - 1 >= 0 Then

        ListBox3.Enabled = True

        Button3.Enabled = True

    End If

    For Each path As String In ListBox3.SelectedItems

        System.IO.File.Delete(path)

    Next

When I click the button to delete the files, nothing happens. If I remember correctly, the program will just enter into break mode. I do not know what is wrong with the code. To me it looks perfectly fine. But then again, I am still trying to learn VB.Net. Any help is greatly appreciated.

Thanks!

A ListBox does not contain files directly - but ListViewItem object instances which can represent anything - and whose lifetime is independent of the object they represent (such as a file on-disk or a business/domain object).

@Dai Thank you for the information. Is there a way to provide a example for me, to help me build from there. If so that would be greatly appreciated!

Can you add one sample item value from the list box to your question?

@Sunil I have added that, the sample path is: C:TestFolderText.txt but I want to delete all files in the listbox, such as: C:TestFolderText.txt C:TestFolderText2.txt C:TestFolderText3.txt and so on

If you want to delete items from a listbox using a loop you need to remove the items from the highest index and go down to 0. That way the indices of the items won't be changed during removal..
if you want to remove all items use the clear command:

    listBox1.Items.Clear()
