using HalconDotNet;
using System;

internal class Program
{
    static void Main(string[] args)
    {
        HTuple tuple = new HTuple();
        switch ((int)tuple) // ILSpy doesn't generate (int) here, can't compile
        {
            case 1:
                Console.WriteLine(1);
                break;
            case 2:
                Console.WriteLine(2);
