Check to See if File is in Repository with SharpSVN

How do I check if a file is already in a repository (or NOT in the repository) so I can determine whether I need to 'add' it first before doing the check in? (For the record, I have check-in working, but I get an exception when I try to check in a file that has not yet bee开发者_C百科n added to the repository.)

I believe you can use SvnClient.GetRepositoryIdFromUri to verify that a specific file exists. If that method returns false, then you'll need to Add the file to the repository.

While SvnClient.GetRepositoryIdFromUri may work (I wasn't able to get it working), I did find an answer elsewhere on SO which did work (this didn't come up in my original search, so sorry about the duplicate question).
