.net - FTPS (FTP over SSL) in C# -


i need guidance. need develop customizable ftp in c# should configured using app.config file. also, ftp should push data server client again depends on config file.

i appreciate if can guide, if there api or other useful suggestion, or move me in right direction.

you can use ftpwebrequest; however, low level. there higher-level class webclient, requires less code many scenarios; however, doesn't support ftp/ssl default. fortunately, can make webclient work ftp/ssl registering own prefix:

private void registerftps() {     webrequest.registerprefix("ftps", new ftpswebrequestcreator()); }  private sealed class ftpswebrequestcreator : iwebrequestcreate {     public webrequest create(uri uri)     {         ftpwebrequest webrequest = (ftpwebrequest)webrequest.create(uri.absoluteuri.remove(3, 1)); // removes "s" in "ftps://".         webrequest.enablessl = true;         return webrequest;     } }

once this, can use webclient normal, except uris start "ftps://" instead of "ftp://". 1 caveat have specify method parameter, since there won't default one. e.g.

using (var webclient = new webclient()) {     // note here second parameter can't null.     webclient.uploadfileasync(uploaduri, webrequestmethods.ftp.uploadfile, filename, state); }
