How do you get the file size in C#?

I need a way to get the size of a file using C#, and not the size on disk. How is this possible?

Currently I have this loop

foreach (FileInfo file in downloadedMessageInfo.GetFiles())
{
    //file.Length (will this work)
}

Will this return the size or the size on disk?

FileInfo.Length will return the length of file, in bytes (not size on disk), so this is what you are looking for, I think.
