Validating User Input? C#
- by Alex
Hi, in an assignment, I have designed a input validation loop in C#, and I would like it to be able to check for the correct input format. I'm not for sure, but I think my designed loop is not checking the type of input, just what char is entered. I know I could use a try-catch block, but shouldn't you only use exceptions for exceptional situations? This is not an exceptional situation, because I expect that the user would enter an incorrect value.
Input validation is not part of my assignment, so the loop is in a homework assignment, but is not part of the homework assignment.
Question:
Is there a way I could redesign this loop so that it checks for valid input type as well?
Code:
do
{
Console.Write("Do you wish to enter another complex number?: (Y or N)");
response = char.Parse(Console.ReadLine());
response = char.ToUpper(response);
if (response != 'Y' && response != 'N')
Console.WriteLine("You must respond Y or N!");
} while (response != 'Y' && response != 'N');
Thanks!!
