Using an enum as an array index in C#

Question

I want to do the same as in this question, that is:

enum DaysOfTheWeek {Sunday=0, Monday, Tuesday...};
string[] message_array = new string[number_of_items_at         


        

Answer 1

Compact form of enum used as index and assigning whatever type to a Dictionary and strongly typed. In this case float values are returned but values could be complex Class instances having properties and methods and more:

enum opacityLevel { Min, Default, Max }
private static readonly Dictionary _oLevels = new Dictionary
{
    { opacityLevel.Max, 40.0 },
    { opacityLevel.Default, 50.0 },
    { opacityLevel.Min, 100.0 }
};

//Access float value like this
var x = _oLevels[opacitylevel.Default];
