How to import file of the www

Hi!

How can I check that file exists in the internet, because for example the
following is NOT working ...

blnExist =
System.IO.File.Exists("http://www.suomenpankki.fi/ohi/fin/0_new/0.1_valuutta
k/fix-rec.txt")

.... and how do You recommend to import/update file of the net into DataSet
DataTable daily? Any examples available?

Thanks in advance!

No, and indeed it shouldn't. System.IO.File is about file system
objects, not web pages.

Download it using WebClient or WebRequest. If those give you a 404
(HttpStatusCode.NotFound) then that's the equivalent of the file not
existing.
