the following solution worked out me.
private bool ftpupload(fileupload file, string ftpserver, string username, string ftppass, string domainname = "") { // ftp://domain\user:password@ftpserver/url-path // if member of domain, "ftp://domain-name\username:password@url-path" may fail because backslash (\) sent in literal character , internet explorer incorrectly looks file instead of parsing web address. changing backslash (\) in domain-name\username domainname%5cusername works correctly. try { string ftpaddres; if (domainname != string.empty) ftpaddres = "ftp://" + domainname + @"%5c" + username + ":" + ftppass + "@" + ftpserver + "/" + file.filename; else ftpaddres = "ftp://" + username + ":" + ftppass + "@" + ftpserver + "/" + file.filename; using (var webclient = new system.net.webclient()) { webclient.uploaddata(new uri(ftpaddres), file.filebytes); } } catch (exception e) { throw new exception(e.message, e); } return true; } thanks @freelancer link posted in comment.
