Do format-patch from the commits between a specific Tag and the last commit

Question

How do I do a format-patch from the commits between a specific tag and the last commit?

I need to do it using git commands and\or C# code.

Currently, I succeeded to get all the relevant commits by:

git log --pretty=oneline HEAD...tag

now I need to know how to do a format-patch just on them

git format-patch receives the same range argument format as git log. You'd also probably want to add the -o argument to specify the output directory for thee patches:

git format-patch HEAD..tag -o /tmp/patches
