Help in downloading files using C#
i am creating a small application to download some files i just need some code help
for the following things

1. Checking the file size of remote http file it has to only download if the remote file is newer
2. Downloading the files from web with progress bar (preferring multiple downloads at a time)

I am not an programmer but i will understand the logic if i tried once
if you found any links that help me please post them.
