How do I call a static member of a CLR type?

Site seeder question: I have defined a CLR data type, used for storage of localised currency. I have a static member on that class which takes as it's input a string representing the currency symbol or name, and a decimal representing the value. How do I call it from within T-SQL code?

Edit -> Woot - going for my tumbleweed badge with this one! I'll provide an answer after a couple of days if there aren't any.
