Opening Excel file and returning it as context response

Here's what i'm trying to do:
- User clicks a button on the asp.net page (C#)
- Open an excel file
- Edit the content of the file
- Returning the excel file for user to download

I have found the way to open the excel file and edit the content (I'm replacing things like "[%customer_name%]" with some text that the user input before clicking the button). But i'm not sure how to have the excel file being returned into the context.Response, so that the user can be prompted to download the excel file.

How do i do that?

Many thanks in advance, and apologies if this has been asked before.. i just couldnt find it..

To download a file in .net is not that hard

C#

//Set appropriate ContentType.
Response.ContentType = "Application/xls";

string fileh = MapPath("myFile.xls");

//Write the file to the output stream.
Response.WriteFile(file);
