Title Body

There seem to be three choices for implementing publicly accessible constants in C#. I'm curious if there are any good reasons to choose one over the other or if it's just a matter of personal preference. Choice 1 - private field plus property getter private const string _someConstant = "string that will never change"; public string SomeConstant { get { return _someConstant; } } Choice 2 - property getter only public string SomeConstant { get { return "string that will never change"; } } Choice 3 - public field only public const string SomeConstant = "string that will never change"; Which do you recommend and why? Update Apparently, this has turned into a discussion of whether to use const or static readonly . Not exactly what I intended, but it did teach me that Choice 3 is definitely a bad idea because, if the value of the const changes in a future version, it requires all referencing assemblies to be recompiled. However, I don't think anyone has really discussed Choice 2 yet. I'm still curious if there's any disadvantage with having just a getter that returns a value and nothing else.
