I tried using a memorystream as input to an xml file download, so I wouldn't have to create a disk file (to then delete)....

            Response.Clear()
            Response.AddHeader("Content-Disposition", "attachment; filename=" & varFileName)
            Response.ContentType = "text/XML"
            '    Response.WriteFile(varFilePath & varFileName)  < the alt way to do it

            ''---  use memorystream
            varMemTab.Position = 0
            Dim wrkStreamReader As New StreamReader(varMemTab, Encoding.UTF8)
            Dim content As String = wrkStreamReader.ReadToEnd()
            ''---- do the write
            Response.WriteFile(content)

....but it gave an http exception error like it was processing the markup in the Response.WriteFile(content) statement.

Might there be a way to make this work?

Any suggestions would be appreciated.

Thanks!

Make sure that your aspx page doesn't have any HTML markup.

also end the response stream after you have written your file to it


Response.End

WriteFile save the file to disk. To send the file to browser as a download, you have to download the file as a byte array. See if the following helps:
