Forcing user to choose 1, 2 or 3

Hello, im a bit lost! first is a while-loop to make sure input is not null, but then how would I best structure this to make it not move on if input is not 1, 2 or 3? Switch didnt work, since default; sends user back to the menu instead of changing the input

is there any way to make this a part of the while loop? so that it will enter loop not only if TryParse but also if number is not one two or three?

&& (bokTyp < 1 || bokTyp > 3)

did i put it incorrectly? it moves on to the switch anyways

ero•2y ago

Ah, it's || !(bokTyp >= 1 && bokTyp <= 3) Other way around

Still not working, not getting any error messages but it doesnt seem to be checking the second condition before moving on from the while

While(boktype <= 3 && boktype >=1) This should work (!value.IsNullOrEmpty(input)) You can use this to check for null or empty

I was missing one set of ()! now it does check the second condition but instead, doesnt move on despite the number being 1 2 3 :p

string input = "4";

if (!int.TryParse(input, out int x) || x < 1 || x> 3)
Console.WriteLine("foo");

string input = "4";

if (!int.TryParse(input, out int x) || x < 1 || x> 3)
Console.WriteLine("foo");
