Upload file to AS400 using FtpWebRequest

Question

I’m attempting to upload a file to AS400 using C#. The structure is:  ftp server ip address/library/table. E.g. 10.123.1.23/ABCD/XYZ. FileName : sample.txt

The AS400 table has same fields as my file layout. I am able to successfully upload file using ftp commands using PUT command as below.

ftp> open 10.123.1.23

ftp> username

ftp> password

ftp> cd ABCD

ftp> put sample.txt ABCD/XYZ. I get a success message.

But when I try using FtpWebRequest, i get a 550 :” File unavailable or no access” error message.’

I’m not sure how to construct the URI. Currently, my code looks like

FtpWebRequest ftpRequest = (FtpWebRequest)WebRequest.Create(@"ftp://110.123.1.23/ABCD/” + file.Name);

 

Also, i’m unable to browse to the ftp folder using internet explorer or windows explorer. I get the same 550 error.

i'm using .Net 4.0, VS 2010

Any help is much appreciated.

Answer 1

The file on the server should not be specified in the .Create() call, as it does not yet exist.   See the example here: http://msdn.microsoft.com/en-us/library/ms229715.aspx

@Mike Thanks a ton. That worked. Modified URL looks like this

FtpWebRequest ftpRequest = (FtpWebRequest)WebRequest.Create(@"ftp://110.123.1.23/ABCD/XYZ”);
