Help with Deleting a file after downloading

[microkarl]

Hi all,
I have implemented some code in my page that will generate a .txt file (on the fly) when the user click on an ASP button, then a download box will show up and so the user can download that file. But I want to delete the file right away after the file is finished downloading...

//Here's the code to generate the file... Everything ends @Response.End();

System.IO.FileInfo fileToDownload = new System.IO.FileInfo(myFileName);
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=" + myFileName);
Response.ContentType = "application/octet-stream";
Response.WriteFile(myFileName);
Response.End();

//I tried to change it to become the following, but still doesn't work...
//Response.Close();
//fileToDownload.Delete();

can anyone give me some hint?

Thanks,
Carl

Rather than create and then delete a file on the server you could simple write the contents direct to the response objects outputstream http://www.xtremedotnettalk.com/showpost.php?p=447870&postcount=10 has a simple example.

Thanks for the response, it actually works! The only concern that I have is would there be a threading problem?
