CMD freezes when char or string is passed into var currentamt

Question

I'm trying to add a failsafe if else statement if a accidently string or char is passed into variable currentamt. But if a char or string is passed into currentamt through currentamt = Convert.toint32(console.readline());

Then the commandline freezes and this is my debugging error "Input string was not in a correct format". How do i fix this

I was like ok? So I tried to do currentamt = Console.Readline(); and then complains that it cannot implicitly convert type string to int. But currentamt is a var?

Answer 1

// try this

Int32.TryParse(Console.ReadLine(), out currentamt);

Answer 2

Can you please link your code?

You could use TryParse() and maybe exception handling.

Answer 3

I think var currentamt would be int as it is initialized with 0.

Answer 4

Ok i put the Int32.Tryparse(Console.Readline(), out currentamt) into the if statement and that worked thanks bud

Answer 5

To improve your conditional statements:

answer = Console.ReadLine().ToUpper().Trim();
if (answer == "YES" || answer == "Y") {...}
