I’m studying about the RegularExpression, But I don’t quite understand.
In my Model the property CPF must be filled in by numbers only:
[RegularExpression(@"[0-9]", ErrorMessage = "CPF deve conter apenas números")]
public string CPF { get; set; }
I wanted to understand how to validate using Regularexpression.

Well, the expression is not exactly right. The correct would be:
[RegularExpression(@"[0-9]{11}", ErrorMessage = "CPF inválido. O CPF deve conter 11 caracteres e apenas dígitos")]
public string CPF { get; set; }
This is because the way it was you are only validating a digit from 0 to 9, not 11 digits.
Validation is done on the client. Make sure that the Bundle jQuery Validation is added to View:
@section Scripts {
@Scripts.Render("~/bundles/jqueryval");
}
It worked here @Gypsy, I will post another question about using Mask in input, but using through model, if you can help me, thanks
Just paste the link here for me.

\d = [0-9] Let’s remember him :D

Its validation means, the input value of CPF should only receive numbers (or only one) that is expressed by [0-9] the square bracket means it’s a list, the 0-9 is the range of caractars allowed.
The problem seems to be that only one digit is captured, a 'normal' CPF has 11 numeric digits (it has that other 'Cpf' cic an Amarelinho that has a different format), you can report it through a fixed quantifier {11} which is the number passed between the keys.
What a grammar, eh, young man?
@Ciganomorrisonmendez which part?
...a normal CPF has 11 numeric digits.
@Gypsy omorrisonmendez lol, parallel processing, thank you I will fix.

If it should only contain numbers, why not use a
intinstead of a string?– dcastro
