Console.ReadLine() returns a string? so a string value that can also be null In an event where it is null, you can't .ToLower() it The most proper way to deal with it would be using a null-coalescing operator, for example

var text = Console.ReadLine()?.ToLower() ?? "";

var text = Console.ReadLine()?.ToLower() ?? "";

So I should replace line 35 with var text = Console.ReadLine()?.ToLower() ?? "";

A simpler but less idiomatic way would be the null-forgiving operator that basically says "trust me bro, this is not null". But if it does happen to be null, well, you're out of luck and your app breaks:

var text = Console.ReadLine()!.ToLower();

var text = Console.ReadLine()!.ToLower();

Yes
