Validating password using regex c# [duplicate]

Answer 1

I recommend you create separate patterns to validate the password:

var input = "P@ssw0rd";

var hasNumber = new Regex(@"[0-9]+");
var hasUpperChar = new Regex(@"[A-Z]+");
var hasMinimum8Chars = new Regex(@".{8,}");

var isValidated = hasNumber.IsMatch(input) && hasUpperChar.IsMatch(input) && hasMinimum8Chars.IsMatch(input);
Console.WriteLine(isValidated);
