Is there a way to create a static readonly array, but the values are calculated at build time

Question

Is there a way I can create a static array with readonly values, but using some logic to create it? Let me try to explain:

I know I can do this:

public static readonly int[] myArray = { 1, 2, 3 };

but is it possible to do something like:

public static readonly int[] myArray2 = 
{
    for (int i = 0; i < 256; i++)
    {
        float[i] = i;
    }
};

EDITED: A good solution to my question: Static Constructor! http://msdn.microsoft.com/en-us/library/k9x6w0hc%28v=VS.100%29.aspx :D

Answer 1

What you can do is:

public class YourClass
{
    public static readonly int[] myArray2 = null;

    static YourClass()
    {
        myArray2 = new int[256];
        for (int i = 0; i < 256; i++)
        {
            myArray2 [i] = i;
        }        
    }
}

Or:

public static readonly int[] myArray2 = Enumerable.Range(0, 255).ToArray();
