pre-defined constants for non-trivial data types

Question

My Goal: Create a C# class for predefined errors that have both an ID and a Message. Here was what I tried:

public class MyError
{
    public static readonly         


        

Answer 1

The type is not mutable. The Code Analysis gets confused by having public readonly fields.

You can fix the code analysis issue by making your public fields public properties:

public MyError(int id, string message)
{
    this.id = id;
    this.message = message;
}
private readonly int id;
private readonly string message;
public int Id { get { return id; } }
public string Message { get { return message; } }
