.Net - How to write a Stream to a file in specified location

I am trying to download a zip file from an FTP location to a directory in the server harddisk.

I am getting the zip file as a ReponseStream from the FTP location.

How can i write this z开发者_运维知识库ip file to a specified directory. I can't say what the size of this file will be.

Thanks in advance.

Can you just use WebClient.DownloadFile("remote file", "local file")? It's so much simpler.
