Creating a constant Dictionary in C#

Question

What is the most efficient way to create a constant (never changes at runtime) mapping of strings to ints?

Answer 1

I am not sure why no one mentioned this but in C# for things that I cannot assign const, I use static read-only properties.

Example:

public static readonly Dictionary NewDictionary = new Dictionary()
        {
            { "Reference1", Array1 },
            { "Reference2", Array2 },
            { "Reference3", Array3 },
            { "Reference4", Array4 },
            { "Reference5", Array5 }
        };
