当有人输入错误的答案时，C＃Console关闭

Question

I've been trying to figure out how to get my console to close when someone finally types the wrong answer (in my quiz)?

I've tried Environment.Exit(); but it doesn't work... It gives me the error: "no overload for method 'Exit' takes 0 arguments.

Here's a bit of my code. I've marked with a comment where I'd want the quit code to be:

Console.WriteLine("In what country was Adolf Hitler born?");

string userAnswer = Console.ReadLine();

if (Answers.AnswerOne.Equals(userAnswer))
{
    Console.WriteLine("Congratulations! {0} is the correct answer!", Answers.AnswerOne);
    Console.WriteLine("\n\n(Press Enter to move on to the next question...)");
}
else if (!Answers.AnswerOne.Equals(userAnswer))
{
    Console.WriteLine("Sorry! You wrote the wrong answer!\nThe correct answer was {0}.", Answers.AnswerOne);
    Console.WriteLine("\n\n(Press Enter to exit...)");
    Console.ReadKey();
    //EXIT CONSOLE
}

Otherwise, the code runs perfectly fine.

Thanks in advance.

Answer 1

The error message you are getting is 100% correct. Environment.Exit() needs to be called with a parameter.

Try Environment.Exit(0) . The .Exit() method takes an int value to indicate the 'exit code'.

Exit code to be given to the operating system. Use 0 (zero) to indicate that the process completed successfully.

Answer 2

I think you will find multiple answers here: How do I specify the exit code of a console application in .NET?

Google is your friend. :)

As for Environment.Exit(int exitCode):

// Summary:
//     Terminates this process and gives the underlying operating system the specified
//     exit code.
//
// Parameters:
//   exitCode:
//     Exit code to be given to the operating system.

0 is the default exit code when nothing went wrong.
