Regularexpression only letters in the Model

Question

Using the following Regularexpression in the Model:

[RegularExpression(@"^\d+$")]
public int ano_da_configuracao { get; set; }

I get the following result:

I tried as follows to accept only letters:

[RegularExpression(@"/^[A-ZÁÀÂÃÉÈÍÏÓÔÕÖÚÇÑ ]+$/")]

thinking that it could achieve the same result, but it didn’t work.

How to fix this expression so it works as the first example?

Answer 1

The right thing would be:

[RegularExpression(@"^[a-zA-Z]+$", ErrorMessage = "Use apenas caracteres alfabéticos.")]
public String MinhaString { get; set; }
