What I am trying to is automatic bidding process in Ebay site...

WebClient class can uploads form data easily.

I have collected ebay url & form data to uploads..
Most of process is quite easy and simple. But ebay webserver send me your password is not valid...
But the password is clearly correct.. you can type it at the result page and submit. Then you can see a message - bidding has ended and you are logged in. <- This is the message I want.

I can not find where is a wrong part. Some code is worng?? Or whole different way..? Please help me~~~~

You might want to sniff the session using a network sniffer. I would do the
following

1) USe the browser to do the same scenario. Capture the scenario using a
network sniffer.
2) Do the same using your code. capture it using a network sniffer.

now compare the two sniffs and see what the difference is. That should
explain why it is failing.

I would use https, and pass the userid and password as part of the http
protocol.
