Hi All,

I am using following code for file deletion on server after downloading at client site.

The code is working from visual studio but NOT working when website is hosted even on the coding machine.

C#

Dim filefullname As System.IO.FileInfo = New System.IO.FileInfo(theFileName)
                Response.Clear()
                Response.AddHeader("Content-Disposition", "attachment; filename=Observation_Report.docx")
                Response.AddHeader("Content-Length", filefullname.Length.ToString())
                Response.ContentType = "application/octet-stream"
                Response.WriteFile(filefullname.FullName)
                Response.Flush()
                System.IO.File.Delete(theFileName)
                Response.End()

Put a breakpoint and debug to find out what is the value hold by filefullname.FullName. Is it the fully qualified path?

Thanks for the reply!
I have checked and the path is correct. Infact filefullname.fullname and thefilename are same.
Also code is working fine when pkg run from VS but when hosted, the file is not deleted.

File deletion on IIS host server requires permission. Do the identity impersonation to user who has admin permissions.

First off, I'll bet the error tells you exactly what the problem is. However, I'd bet it's a permissions issue since it works on your machine but not hosted. You'll need to grant whatever account is hosting the IIS application pool the proper permissions to delete files from that path.
