Rename File Download ASP.NET C#

I have a module in ASP.NET C# that rename an uploaded file to a new one. In case, if original file name is: thisisatext.txt, when user uploaded into my server it will be renamed to TXT201302.TXT.

All activities are recorded to database, with this structure:

| id    | oldfilename     | newfilename   |
| 1     | thisisatext.txt | TXT201302.TXT |

Now I want to make a download module that rename uploaded file to their original filename, that is: thisisatext.txt

How can I do it?

You have to set the file name in the Content-Disposition http header

Response.AddHeader("Content-Disposition", "attachment; filename=" + oldfilename);
Response.ContentType = "text/plain";

Response.BinaryWrite(fileContents);   //byte array contents of file
Response.End();

File will get downloaded, and user will be prompted to save it with the old file name.
