How to verify the downloaded file completeness with webclient

[makinha]

Hello All,

I can use WebClient.DownloadFile Method to download target file from the website,

like WebClient.DownloadFile("http://www.abc.com/a.pdf", "D:\a.pdf")

but how can I verify the file is exactly the same as the source file?

For example, when we try to download some big files from the internet e.g. Win XP - service pack 2, the IE download windows may sometime report download completed and terminate the download process, but when you go check the downloaded file, the file size may only a few hundred KB.

Is there a way to check the file size on the internet? and allow us to compare the file size after download? thanks.
