Question

I have the method GetOption(5) that returns the value 5K23 and I need to get the last two characters of the string the thing is the value is a string value, so I would need to use Substring I have tried doing:

if( Convert.ToInt32(GetOption(5).Substring(GetOption(5).Length-2, 2) % 2 == 1) )

I can’t seem to get it right, can anyone help me out.

Thanks

You don’t really need last two digits to determine whether number is odd

var option = GetOption(5);
var isOdd = int.Parse(option[option.Length - 1].ToString()) % 2 == 1;
