The goto command doesn't work

Question

When I'm doing the code without the goto command it works, but when I add the :Start it get an 8 error.

Here is the relevant code:

        :Start
        Console.Write("Do you want the yes or no?");
        string what = Console.ReadLine();
        switch (what)
        {
            case "yes":
                Console.WriteLine("You choose yes");
                break;
            case "no":
                Console.WriteLine("You choose no");
                break;
            default:
                Console.WriteLine("{0},is not a word",what);
                goto Start;
         }

Answer 1

The correct syntax is Start:. But, instead of goto, you should set this up in a loop:

bool invalid = true;
while (invalid)
{
    Console.Write("Do you want the yes or no?");
    string what = Console.ReadLine();
    switch (what)
    {
        case "yes":
            Console.WriteLine("You choose yes");
            invalid = false;
            break;
        case "no":
            Console.WriteLine("You choose no");
            invalid = false;
            break;
        default:
            Console.WriteLine("{0},is not a word",what);
     }
}
