C# how to exit console with specific command?

[WereCat]

Hi, I recently started learning in C# but I cant figure out how to do this. I am just playing around with code so far and barely just scratched basics and I know already how to make simple stuff but now I would like to make something more user friendly but I want to make such console that can exit on command.

I know that I can write at the end of the code:

Console.ReadKey ();

and then press anything and it will exit but I want to make it so it will exit only when it is typed "quit" or when the console asks you if you want to exit or continue.

 

Console.WriteLine ("Do you wish to exit or continue?\nPress E if you wish to exit or press C if you wish to continue");

 

if(condition to press C) {

// continue

} else if (condition to press E) {

// exit ... I dont want this to be Console.ReadKey (); to press any key to exit

} else {

Console.WriteLine ("You entered bad input");

}

I think this should be what you want

string response = Console.ReadLine();if (response.ToLower() == "quit") { //Doesn't matter whether they use upper or lower case  //quit} else {  //continue}

Thanks, that helped but I had to delete .ToLower because I was geting error that operator '==' cannot be applied to operands of type 'method group' and 'string'.

Oh yeah I forgot to add the () to the end of that command. I've updated it now, and that version should hopefully work.

Alternatively, if you're happy with it being case sensitive, it's fine without it.

Yep, it does work. Once again, thanks!

Best practice for comparing strings like this and ignoring the case is by using C#'s built in StringComparison comparers.

var stringLower = "string";var stringUpper = "STRING";var sameLetters = stringLower.Equals(stringUpper, StringComparison.OrdinalIgnoreCase); // true

Agreed. I would also use this method.

 

WereCat: Alternatively you can write it like this.

String.Equals(stringLower, stringUpper, StringComparison.OrdinalIgnoreCase)

Both work the same way. Sometimes I find one is more readable than the other. It's mostly personal preference though. Just wanted to let you know the option was there.

Thanks. I appreciate the help. I will try it after work.
