Array error reference error in asmx project

Question

This is a very mysterious behavior.

In my C# ASP.NET project (.asmx web service), constants are assigned in a file Constants.cs.

namespace MyProject
{
    public class MyConstants
    {
        public const string MyString = "Mars";
        public static readonly string[] MyArray = { "Pluto", "Eart", "Venus" };
    }
}

If MyString is called in main unit with

string StrPlanet = MyConstants.MyString;

all works.

If I call ANY element of MyArray and assign it with

string StrPlanet = MyConstants.MyArray[0];

I get this error:

System.IndexOutOfRangeException: Index was outside the bounds of the array.
at MyProject.Constants..cctor()

Where is mistake?

Thanks.

Please have a look at the answers to Declare a const array and see if any of them provide a good solution for you. — Andrew Morton

The above code seems to work fine. Are you sure you are not looping over the MyConstants.MyArray? Maybe your index is going out of bounds there. — Rahul Sharma

Same code in other project works fine. It is very mystery for me. — NicoBlu

"Same code in other project works fine." - So the code works for you? — nicomp

Try making the class static: public static class MyConstants

Also You could try to use List<string> instead.

but I bet it not in a asmx class - which is static by default......
