Expressing intent that method parameters are immutable for reference type arguments
If I want to express intent that a reference type argument is passed into a function, but isn't mutated, may I do so with
in keyword, or should I use ref readonly, or is this entirely innapropriate (has performance downsides)?
I do know that I also still need to do the hard work of making sure that the class's members are readonly too, if I want "true immutability".0 Replies
