C# .ASP uploading files to SQL

The bolded line of code below works when ran locally....but will not work when published to the server and ran from the web.
The error it gives is: "can't find "c:/....."
I know what it's doing....it's trying to find that path/file on the server when it needs to be looking locally.
How do I make it look locally for that file/path so it can be converted to a stream?
I'm using the .ASP fileupload button that visual studio provides.
NOTE: the word filePath below is just a variable.....as I said above, I successfully load the file completely into my SQL Database when it's ran locally. I just can't make it look locally for a file when ran from the server.


FileStream fs = new FileStream(filePath,FileMode.Open, FileAccess.Read);

Thanks for any help/advice you can provide.
