Boolean and strings

Question

hey folks!
i have this simple code

Console.Write("Are you Cool?");
string str = Console.ReadLine();
if (str == "yes")
{
Console.WriteLine("HAHA! THAT'S NOT TRUE!");
}
if (str == "no"){
Console.WriteLine("no? weeell.....i think you are");
}
if (str != "yes" || "no") {
Console.WriteLine("I'm Sorry, I Didn't understand you...doofus");
}
how do i make this work? it says it does not work with || since bool values cannot have bool operands
Could anyone help me with this? any help is really appreciated :D

Answer 1

if(str != "yes" && str != "no")
....

Answer 2

Because you are asking if both are true, if string is not "yes", and it is not "no" then print something

Answer 3

Hm, you could write all the cases, for example if(str=="YES"||str=="Yes"||str=="yes")

Answer 4

What @Filip said.
Also you could do if, if else, else:
Pseudo code:
if(yes)
...HAHA
else if(no)
...no?
else
...doofus

Answer 5

string str = Console.ReadLine().ToLower();
str is now all lower case so you only need to check with "yes" and "no".

Answer 6

Easiest is regex but idk how it works in cs...

Answer 7

Thanks! that worked! may i ask for an explanation of why AND works but not OR?

Answer 8

is there also an easy way to make the code non-case sensetive? so that you can write ex: "YES", "Yes" or "yes"?

Answer 9

All the things i asked about works now :D
Filips "if(str != "yes" && str != "no")" gloriously solved my problem!
Jafcas "string str = Console.ReadLine().ToLower();" made my code cooler!

Thanks a bunch!
