I'm hoping someone here can help me out. I am trying to read the response from the ftp server after a PutFile command. If I try to simply read the response:

jobid = client.PutFile(localFileName, filename);
response = client.ReadResponse();

I get this error:
System.InvalidOperationException: No response from the server is expected.

Yet in the log fie there re two responses after the STOR command is sent.

Command: STOR ZENT001A.jcl
Response: 125 Accepting JCL to submit
Response: 250 It is known to JES as J0001904

Is there a way to read the raw ftp server response?

Here is the log file for the entire transaction.

When the PutFile method finishes, it has already transferred the file and read all outstanding responses. There is no further response to be read at that point and therefore the ReadResponse method fails.

To capture responses processed by the PutFile method, use Ftp object's ReadResponse event (add a custom event handler before the PutFile method is called and remove it afterwards).

Thank you. That was just what I was looking for.
