Question

What I just want is to initialize a string[] array constant by specifying not only the values, but the indexes they will be attached to.

For example, on:

private static readonly string[] Pets = new string[] {“Bulldog”, “GreyHound”};

I would like to state that BullDog corresponds to index 29 and GreyHound to 5 (Like php 🙂 )

Any suggestion?

Cheers,

If you have some flexibility in terms of your data structure, it would be more efficient to use a Dictionary<int, string> instead of an array for this behavior.

Example (if you are using C# 3 or above):

var pets = new Dictionary<int, string> {
    { 29, "Bulldog" },
    { 5, "Greyhound" }
};
Console.WriteLine(pets[5]);

Same example for legacy applications:

Dictionary<int, string> pets = new Dictionary<int, string>();
pets[29] = "Bulldog";
pets[5] = "Greyhound";
Console.WriteLine(pets[5]);
