The Pivo FTP component is a fully featured, easy to use implementation of the FTP protocol for .NET, ASP.NET and COM based applications. Fully compliant with RFC 959 and related RFCs, the component has been thoroughly tested with all popular FTP servers. The component is written in 100% managed C# code.

Pivo FTP is a Server component completely written using .NET technology. It can be used with any window, web based .NET applications and COM clients to programmatically add FTP functionality.

Pivo FTP is a low overhead, highly optimized assembly that only needs the Microsoft .NET (or equivalent) framework to run. Any system that can support the Microsoft.NET framework will be able to use Pivo FTP.

Pivo FTP can be used from any environment supported by .NET. These environments include winforms, ASP.NET, console applications, components, or web services. Pivo FTP supports a list of Asynchronous functions.

Microsofts .NET Framework class library contains no classes that will allow developers to access File Transfer Protocol (FTP) services directly.

KCommons FTP component was designed to compensate for the fact that .NET lacks FTP support.

With this FTP component, programmers can build either Windows Forms or ASP.NET (Web Forms) applications that will allow users to send or receive a single file or multiple files, using the FTP protocol.

Operations for synchronous and asynchronous (using a callback or an event) transfers are supported. KCommon supports passive mode, but does not support active mode, which could cause problems with poorly written firewalls. Recall that in passive mode, the data flow is set up and initiated by the FTP client, rather than the server.

This means improved security for the client computer, because it wont have to deal with data flow being set up by the server. The component is written in C#.

It is not marked as CLS compliant. It does not support proxy servers. The online description erroneously refers to an FtpSession type (it should be Session).

Whats New in This Release:

· Removed FileCollection and DirectoryCollection
· Added support for VBs for each statement
· VB client can directly access FtpDirectory.Files and FtpDirectory.SubDirectories with for each statement now

Kellerman NET FTP description
Kellerman .NET FTP is a robust and easy to use .NET FTP Component that supports FTPS and proxy servers Kellerman FTP is a robust and easy to use .NET 2.0 FTP component. It supports FTPS and proxy servers. All the standard FTP operations will be supported plus a multitude of other features that will help shorten development time. Kellerman FTP has the most features of any FTP component available.

Whether FTP is needed for a back end process or as part of an end user interface; the Kellerman .NET FTP library can handle it all. If there is a server in New York and a server in Los Angeles, Kellerman FTP can handle all the file date differences by simply specifying the GMT offset of the FTP server.

Kellerman FTP provides numerous progress statistics, including estimated time to completion, and calculating peak and average KB/sec. These statistics are critical for end users to know how long transfers will take. Below are some of the other powerful features of Kellerman FTP.

Here are some key features of "Kellerman NET FTP":

· Easy to Use - A full GUI FTP client demo is included. Source code is provided in both VB.NET and in C#.

Mabry Software has been designing, writing, and supporting Internet components for almost a decade. Mabry used this experience in designing Ftp/NET from the ground up to take advantage of the exciting new features of Microsofts .NET platform.

FTP/Net fully supports both the synchronous and asynchronous programming models as designed by Microsoft. Each method such as GetFile or BeginGetFile contains a number of useful overloads that provide flexibility and functionality found in no other FTP component. The synchronous model can be used where it is not a problem to block the thread that is invoking the method. The asynchronous model, which was designed to be 100% compatible with the .Net frameworks model, can be used where it is not desirable to have a thread blocked for the duration of a methods execution.

FTP/Net is also providing a number of useful events that are fired during both synchronous and asynchronous method execution. The Progress event is fired periodically as files are sent and received. A DirectoryItem event is fired as directory listings are returned, enabling you to update UI elements as data arrives. And the StateChanged event can be used to track the state of method invocation and provide status information to your users.

FTP/Net includes everything required of a modern FTP client component including the ability to restart interrupted transfers, firewall and proxy traversal support, and easy-to-use methods for sending custom commands and receiving the servers responses.

Unique in the industry, Mabrys FTP/Net also includes FtpWebRequest, FtpWebResponse, and TFTP objects. FtpWebRequest and FtpWebResponse are subclasses of WebRequest and WebResponse, respectively, and provide easy integration with the .Net frameworks HTTP request design.

As always, Mabry Software pushes the boundaries of what is required in components. The TFTP class provided by FTP/Net continues that tradition by including, among other things, complete support for the latest TFTP-related RFCs, a feature not found in other TFTP components. And, like the Ftp class, both the synchronous and asynchronous programming models are fully implemented in the TFTP class.

When you buy FTP/Net you get a complete set of FTP components designed especially for the .Net framework. Compare FTP/Net with the offerings of other vendors and you will see that Mabrys FTP/Net is the best FTP solution available.
