. NET operations on files on an SFTP server

Because the service provider migrates from the FTP server to the SFTP server, alas ~ ~ ~, the bitter force we will change to the right. Now let's talk a little bit about how this is achieved.

----------------------------------------I'm a shameless split-line------------------------------------------------------------

Do not repeat the difference between FTP and SFTP, only to mention a little to a certain extent the latter more secure, the need for students to visit http://www.cnblogs.com/mfryf/archive/2013/05/29/3107286.html to learn more, thank you!

Well, since we have to go to the server to operate the file, we first have to log on to the server, just like other servers, we need an address, user name, password, may also need a port number.

Here I am with the help of a third-party plugin, Sharpssh 1.1.1.13, which is the address http://www.tamirgal.com/blog/page/SharpSSH.aspx (you can download it yourself).
