Bool in C#

Question

Hey (:
Can you please tell me when would you use bool in c# ?
Why ?
It could really help if you'd give an example (:
Thanks in advance!

Answer 1

inbal maslow beiber karsenty , there are some issues in your posted code. This can confuse people, even if you have given a hint for this. Thanks

- <int> and <if> are spelled upper case, but should be lower case
- <bool> in Console.WriteLine(bool) creates an error -> Invalid expression term 'bool'

Here is a sample that demonstrates how it could work. code is made for demonstration only, not for use in a real project.

Console.Write("please enter 1 letter: ");
char inpChar = Convert.ToChar(Console.ReadLine());

bool charState = char.IsLower(inpChar); // this checks if input is lower case. if Yes, charState will <true>, otherwise <false>

Console.WriteLine(inpChar);
Console.Write("input character is lower: ");
Console.WriteLine(charState);

Answer 2

Is it like:
Int x = 2;
Int y = 5;
If(x<y){
Console.WriteLine(bool);}
else{
Console.WriteLine(bool);}

I know it's not the syntax, but that's how I think it supposed to look like....

Answer 3

Some situations are either true or false. Nothing else in those cases you use bool.

Ischecked for a checkbox
IsValid
