[RESOLVED] How to get the size of a file if file is located on a sever

[Netmaster]

How can I get the size of a file in MB if the file is located on a server?

If the file is on a computer I would do this:

Dim file As New IO.FileInfo("c:\myfile.rar"))
label1.text = file.Length
' or: label1.text = (file.Length \ 1024) \ 1024 if i want the size in MB (i guess)

But what about if the file is located on:
http://www.mywebsite.com/myfile.rar

Thank you in advance,

Andrea.
