.Net Core=I want add personality rules for UserValidator

Question

For Example; I have password column in the table. AnyBody while enter system must write password. I want contain password minumum one character such as(/,-,?,+,!). I did such one code;

public UserValidator()
{
    RuleFor(p => p.Password).MinimumLength(10);
    RuleFor(p => p.Password).Must(MustBeCharacter);
}
private bool MustBeCharacter(string arg)
{
    return arg.Contains("."+","+"?"+"!"+"*"+"-"+"+");
}

I take a problem. system want all of them ("."+","+"?"+"!"+"*"+"-"+"+"). but I want minimum one more. How can I do this rule. Thank you so much

Answer 1

System want all of them because you are looking for entire string and not one character.

you need array first

private string[] arr = [".",",","?","!","*","-","+"];
private bool MustBeCharacter(string arg)
{  
        return arr.Any(s => args.Contains(s));
    
}
