Recently working on a FTP solution using C# , i encountered an error “The remote server returned an error: (530) Not logged in.”
The code i used was following:
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftp://xxxxxx/file.txt);
request.Method = WebRequestMethods.Ftp.UploadFile
request.Credentials = new NetworkCredential(usernameVariable, passwordVariable);What was more bewildering was if i modified the code to following, the solution was working fine. But this for obvious reasons is not an option as the username cannot be hardcoded
//works but implausible to use in realtime solutions
request.Credentials = new NetworkCredential("dmn/#gsgs", password); Some googling revealed that special charcters create issues in the NetworkCredential Object. Hence some playing around worked for me, and it works irrespective of wether i do a FTPWebRequest or WebRequest.
Solution:
Instantiate NetworkCredential object with three paramters (username, password, domain) and make sure to normalize the string variables while instantiating the NetworkCredential Object.
i.e:
//this works
request.Credentials = new NetworkCredential(usernameVariable.Normalize(),passwordVariable.Normalize(),domainVariable.Normalize());Note: Normalize the string while instantiating the NetworkCredential object like above . The following doesnt work:
string usr = usernameVariable.Normalize()
string pwd= passwordVariable.Normalize()
string dom = domainVariable.Normalize()
request.Credentials = new NetworkCredential(usr,pwd,dom); // wont work
Hope it helps !!
