C# input has to be 5 digits -

i have question asks user come in pupil number, how can create take 5 digit number. input beingness added object

console.writeline("enter pupil number: ");

then

studentobject.studentnumber = int.parse(console.readline());

i've tried using

if (console.readline().length != 5) { //do } else { //do }

but won't work, .length says can't convert type int bool. i'm stuck, help please?

you can utilize regular expressions:

string input; { console.writeline("please come in pupil number:"); input = console.readline(); } while (!regex.ismatch(input, @"^\d{5}$")); // <- 5 digits expected // input contains 5 digit string int number = int.parse(number);

p.s. in case input should "five digit number, not starting zero" regular look has changed that:

while (!regex.ismatch("12345", @"^[1-9]\d{4}$")); // 5 digits, not zero-starting
