constants

There seem to be three choices for implementing publicly accessible constants in C#. I'm curious if there are any good reason 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?

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
