Command Line Parser Library - Boolean Parameter

Question

I try to pass a boolean parameter to a console application and process the value with the Command Line Parser Library.

[Option(\'c\', \"closeWindow\", Requir         


        

Answer 1

You don't need to add True or False. Using -c will evaluate to True. Not using it will evaluate to False. Somewhere in the documentation there is an example with -v for verbose output. But I can't find it right now. I guess Required=true is not necessary for Boolean options.

Answer 2

bool? behaves the way you want

with :

[Option('c', "closeWindow", Required = true, HelpText = "Close the window.")]
public bool? CloseWindow { get; set; }

the result will be :

-c false // -> false
-c true  // -> true
-c       // -> error
         // -> error if Required = true, null otherwise
