Question

So i want to delete some files when a user closes the browser.

I’m using the page_unload method shown below:

   protected override void OnUnload(EventArgs e)
    {
        base.OnUnload(e);
        string[] uploadedFiles = Directory.GetFiles(Server.MapPath("~/testPdfIn"));
        foreach (string uploaded in uploadedFiles)
        {
            File.Delete(uploaded);
        }
    }

but the page_unload method will just fire right after the page load, deleting the files in folder without the user even closing the browser.

Is there a way to stop the page_unload from firing right after loading and only firing when user closes the browser?

Answer 1

It’s better you detect the browser close event and than call ther server side function using ajax will do for you

<script type="text/javascript">
$(function () {
    $(window).unload(function () {

   jQuery.ajax({ url: "http://localhost:49591/filedelete.aspx", async: false });
      });
});
</script>
