How to post code to Google Code?

I am new to SVN, subversion, etc. I have a C# application in MS Visual Studion 2008 that I would like to share on Google Code.

I have been looking around for some info on how to do that without any luck. I have now installed TortoiseSVN. When I right-click and choose Export or Import I get the following error messages:

"Server sent unexpected return开发者_如何学JAVA value (405 Method Not Allowed) in response to"
"OPTIONS request for 'http://code.google.com/p/atm/source/browse/%23svn/trunk'"

What am I doing wrong?

I believe these might work for you. Screenshots included.
