How do I make a class iterable?

Question

This is my class

public class csWordSimilarity
{
    public int irColumn1 = 0;
    public int irColumn2 = 0;
    public int irColumn3 = 0;
    public int ir         


        

Answer 1

Implement IEnumerable. See Using Iterators (C# Programming Guide)

In your case you could just use the built-in iterator of a List like so:

using System;
using System.Collections.Generic;

class csWordSimilarity : IEnumerable {
    public int irColumn1 = 0;
    public int irColumn2 = 0;
    public int irColumn3 = 0;
    public int irColumn4 = 0;
    public int irColumn5 = 0;

    public IEnumerator GetEnumerator() {
        return (new List() { 
            irColumn1, irColumn2, irColumn3, irColumn4, irColumn5 
        }).GetEnumerator();
    }
    System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator() {
        return GetEnumerator();
    }
}
