问题 As I understand it, the FtpWebRequest.Proxy property denotes an HTTP proxy. I have to issue FTP requests to an external server via an FTP proxy. The only way I've got this to work so far is by creating a script which uses the Windows FTP command and downloading that way. Is it possible to use the FtpWebRequest to download files via an FTP proxy? 回答1: If you have the budget for it - Dart do some great classes for this: http://www.dart.com/ or specifically http://www.dart.com/ptftpnet.aspx 回答2:

问题 I am working on a PowerShell script, which will pull files from an FTP site. The files are uploaded to the FTP site every hour so I need to download the most recent one.

How to Reuse FtpWebRequest Connection

I need to list thousands of files on FTP server, and delete the necessary ones. As you can guess, performance is essential, so I need a way to reuse the FTP connection. There is not enough explanation on MSDN about the connection usage of FtpWebRequests! It only says "Multiple FtpWebRequests reuse existing connections, if possible." What does "if possible" mean? I want to control when to close connection, simple as that! Any idea? Regards Damith Previous connections to the server are reused if possible as long as the KeepAlive parameter to the HttpWebRequest object is set to true .This

I am having a problem connecting a Windows service to an FTP site. I inherited a Windows service from another developer. The service connects to a 3rd party server, downloads a csv file and then processes it. For some reason, the service stopped working (well over a year ago, before I was given the project). So I went back to basics, created a console app and tried the connection/ file download function only in that app. I have tried many different methods to connect to the FTP, but all of them return the same error to my application: The remote server returned an error: 227 Entering Passive
