How to save a file in SQL Server

I have the need to allow a user to upload a file via the web and then save it into a database. THen I also need to be able to retrieve the file for download.

Can someone give me guidance as to code or a sample on how to do this.

Thanks.the sql column is usually set to a type of "image" as this holds binary data.
the file gets uploaded to the webserver and saved to a temp folder.
iv seen samples in the forum where the file is read into a byte array and then from the byte array, is put into the db via a stored proc.|||Look at BLOB, although it's normally better not to store binary data in your DB.
