This article describes the implementation of C# custom FTP operation encapsulation classes. Share it for your reference. The details are as follows:
This C# class encapsulates common operations of FTP, including connecting to ftp servers, directories and files on list servers, downloading files from ftp, uploading files to ftp servers, etc.
