It can't find an overload of the method that matches the signature of the delegate

letterletter is a

char

char

, I do not think

char

char

s have ContainsContains method.

TheBoxyBear•9/5/22, 8:30 PM

What do you mean by a letter containing a character?

TheBoxyBear•9/5/22, 8:30 PM

The letter is the character

Anar•9/5/22, 8:30 PM

How would a letter contain a

char

char

? It is already a

char

char

Anar•9/5/22, 8:31 PM

Did you mean to type specialCharacters.Contains(letter)specialCharacters.Contains(letter)?

TheBoxyBear•9/5/22, 8:31 PM

Just use a lambda in Any that compares the character to the letter

TheBoxyBear•9/5/22, 8:32 PM

yes

TheBoxyBear•9/5/22, 8:33 PM

VVerracciii like this? `if((specialCharacters.Any(s => letter == s)))`

Anar•9/5/22, 8:39 PM

Why do it with linq

AAnar Did you mean to type `specialCharacters.Contains(letter)`?

Anar•9/5/22, 8:39 PM

That is just this

Anar•9/5/22, 8:41 PM

You can.

TheBoxyBear•9/5/22, 8:45 PM

Could start by comparing the character values instead of every number on the range

Anar•9/5/22, 8:45 PM

Because that is not how ranges work.

TheBoxyBear•9/5/22, 8:45 PM

if < -26 or > 26

Anar•9/5/22, 8:45 PM

It takes starting value and count, so that returns [-26, 0)[-26, 0).

TheBoxyBear•9/5/22, 8:45 PM

That too

TheBoxyBear•9/5/22, 8:48 PM

Might have to cast the char to a number first

Anar•9/5/22, 8:48 PM

Nah, it is implicitly casted.

TheBoxyBear•9/5/22, 8:48 PM

Then yeah just use comparison operators

VVerracciii what about if it isnt?

Anar•9/5/22, 8:48 PM

Then you check if it is either less than -26 or greater than 26.

Anar•9/5/22, 8:51 PM

TheBoxyBear•9/5/22, 8:52 PM

Enumerable.Range is more useful for explicitely doing something with all numbers

TheBoxyBear•9/5/22, 8:52 PM

In your old code, it would go "is it -26? is it -25? is it -24? ..." all the way to 0

Anar•9/5/22, 8:53 PM

Mhm, linq abuse. when
