Easily Add Comprehensive FTP, SFTP File Transfer Capabilities to Your .NET Apps
Editor: NetXtremeFtp .NET class library offers a number of classes that make the work of transferring files directly from your application using FTP/SSL (an extension of FTP which is fast becoming a standard for secure FTP) and SFTP (a powerful and secure file-transfer protocol that runs over an SSH session) more easily. The FtpClient and SftpClient classes provide a number of convenience asynchronous methods and events that allow you to quickly Create applications which can handle file transfers simultaneously. The library also offers the flexibility, ease of use and rapid development features of a component without the complexities of working with the native socket class or in-depth knowledge of how the File Transfer Protocols are implemented.
