The Xceed FTP Library for .NET is designed to work well with all types of FTP servers. It provides built in support for Unix, VMS, AS/400 and DOS server types. Thanks to features such as the ability to create custom listing parsers and support for various FTP tweak properties, the library can also work with almost every other lesser-known FTP server type.

Feature:

• .NET technology
  
  • 100% managed code written in C#, source code included in Blueprint Edition
  • Object-oriented design created specifically for the .NET framework
  • VB.NET and C# sample applications included
  • All error handling works through .NET exception classes
  • Objects don't need to be explicitly disposed of
  • CLS compliant (Common Language Specification)
  • Does not use unsafe blocks for minimal permission requirements
  • Documentation fully integrated into Visual Studio.NET
  • Built using System.Net.Sockets namespace
• FTP protocol features
  
  • RFC 959, 1123 and 1579 compliant
  • Supports secure FTP via SSL 3.0 and 3.1 (TLS)
  • Solid, built-in support for various server types including Unix, VMS, AS/400 and DOS.
  • Supports all major FTP operations and allows sending of custom commands
  • Supports FTP passive mode for firewall and proxy server resilience
• Major features
  
  • Send and receive files, folders or entire directory structures quickly and easily
  • Send and receive files to or from disk or memory streams
  • Synchronise a local directory structure with a remote directory structure on an FTP server and vice-versa
  • Support for non-blocking (asynchronous) FTP operations.
  • Operations can be aborted at any time
  • Provides a rich set of events to keep your application notified of all FTP activity
  • Allows you to verify at any time the exact state of the component, including whether it is connected or not, busy or not, sending, receiving, deleting, etc.
  • Obtain a detailed listing of files on the FTP server via a collection object or by events
  • Rename and delete files on the FTP server
  • Resume file transfers from any byte offset
• Component interactivity / Events
  
  • Provides status report events on a file-by-file basis as well as on the entire operation being performed
  • Status reports include various completion percentages, byte counts, file counts, bytes per second, bytes skipped, number of files skipped and more. Displaying a progress bar could not be easier
  • Events are triggered for all major operations such as whenever a file is being sent, received, listed, etc.
  • When sending multiple files and an error occurs, allows you to retry the file, skip it and continue, or abort the entire operation
  • Provides complete file information for the current file being processed.
• Other features　
  
  • Create filters so you can send or receive only files that fit specific criteria such as file size or date
  • Allows you to rename or change filenames and paths before sending
  • Automatic logging to memory or to disk
  • Use the automatic directory listing parser or create your own custom parser for unknown listing formats and FTP server types. You can do this in two ways - through inheritance or by handling an event.
  • Set a timeout limit on all operations and have an exception triggered if it is exceeded
  • Send a file to an FTP server and have the server give it a unique filename
  • Can send files as ASCII or Binary
  • Triggers an event if the connection to the FTP server is lost
  • Allows you to change the user that is currently logged in without disconnecting
  • Built-in tweaks for working with non-standard FTP server types including settable FTP server folder separator character, storage pre-allocation and TYPE command sending.
  • Specify an FTP server by IP address or host name
  • Specify files to send or receive using wildcards
