Question

I have the following code:

    [HttpPost]
    public ActionResult FileUploadMultiple(IEnumerable<HttpPostedFileBase> files)
    {

        foreach (var file in files)
        {
            if (file != null)
            {
                var fileName = Path.GetFileName(file.FileName);
                string extension = Path.GetExtension(file.FileName);

                var path = Path.Combine("C://Reports//36000", fileName);

                file.SaveAs(path);

            }

        }

        return RedirectToAction("Index");
    }

I have 2 files that I am testing on – as such it should loop twice. The first saves fine to the given path. When the code goes and tries to do the second file, I get the following message:

The process cannot access the file ‘C:\Reports\36000\Report #36028.pdf’ because it is being used by another process.

I think I need to do a dispose but, when I tried to do file.Dispose() this didn’t appear to be correct in Intellisense.

You can try this to delete an existing File, before saving:

if (System.IO.File.Exists(path))
 System.IO.File.Delete(path);
file.SaveAs(path);
