Question

Any advantage or difference in using const or Func in a class ?

public sealed class Constants {
  private Constants() {}
  public const string SOME_STRING = "Some String";
  public static Func<string> SomeString = () => "Some String";
}


Debug.WriteLine(Constants.SOME_STRING);
Debug.WriteLine(Constants.SomeString());

For what you’ve shown, use a const. Your intent is clear that way.

A Func is just a function, represented as an object. You don’t seem to need a function, so why use one? A direct access is simpler to understand and more people will expect it. If I saw that usage of a Func, I would definitely do a double take.
