    What?

    If I have a case 42: in C#, I can issue a goto 42 and resume execution after that case? Or how would that work?

    From what I know, labels are only an identifier followed by a colon, like:

    stop: printf("stopped.\n");

    Or just the label and colon on one line and statements following on subsequent lines. I’ve never seen a switch case expression being called a “label”. Very new to me. Would love to see a minimal demonstration example. 🙏

    Edit: huh, I guess you can.

      Yes, you would do goto case 42;
      From MSDN:

      private static decimal CalculatePrice(CoffeeChoice choice)
{
    decimal price = 0;
    switch (choice)
    {
        case CoffeeChoice.Plain:
            price += 10.0m;
            break;

        case CoffeeChoice.WithMilk:
            price += 5.0m;
            goto case CoffeeChoice.Plain;

        case CoffeeChoice.WithIceCream:
            price += 7.0m;
            goto case CoffeeChoice.Plain;
    }
    return price;
}
