C# regular expression expert needed

I want to get the perfect regex pattern to get correct matches from original input string using c#.

Below is original input string
Navi//gate to "https://copyright.gov.in/UserRegistration/frmNewUse//r.aspx" -max//imize

This input will have 4 matches:
1. //gate to "https://copyright.gov.in/UserRegistration/frmNewUse//r.aspx" -max//imize
2. //copyright.gov.in/UserRegistration/frmNewUse//r.aspx" -max//imize
3. //r.aspx" -max//imize
4. //imize

If you can get it done ASAP Please bid on this project
Thanks
