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;
}
