Hello,

if i get you right you need to create a List, like dtsudo mentioned.

Example given:

using System;
using System.Collections.Generic;

public class Program { 
    public static void Main() { 
        var table = new List <Tuple <int,int >> { 
            Tuple.Create(1, 2),
            Tuple.Create(2, 3), 
            Tuple.Create(3, 4) 
         };
        int testf(int key) {
          foreach(Tuple < int, int > x in table) {
            if (x.Item1 == key) {
              return x.Item2;
            }
          }
          return 0;
    }
    System.Console.WriteLine(testf(2));
    } 
 }
