Write the service (or just the page) that will accept the link, access the database based on some identifier contained in the link (maybe row primary key or something) and send binary (file) stream to the client (via response.write).

You want to use Response.Binary write. If you google that you'll see lots of examples. For example, c# - Reading a binary file and using Response.BinaryWrite() - Stack Overflow[^]
