I have the following enumerator
public enum MeuEnumerador
{
[Description("Descrição do item do enumerador")]
Enumerador1 = 1,
[Description("Outra descrição")]
Enumerador2 = 2
}
How do I get the value that is in the Description of the enumerator?
I found a solution creating the following extensions for type Enum
public static T ObterAtributoDoTipo<T>(this Enum valorEnum) where T : System.Attribute
{
var type = valorEnum.GetType();
var memInfo = type.GetMember(valorEnum.ToString());
var attributes = memInfo[0].GetCustomAttributes(typeof(T), false);
return (attributes.Length > 0) ? (T)attributes[0] : null;
}
public static string ObterDescricao(this Enum valorEnum)
{
return valorEnum.ObterAtributoDoTipo<DescriptionAttribute>().Description;
}
Where the ObterAtributoDoTipo<T> extension will return the attribute that is requested, in this case the Description . Example usage:
var meuEnumerador = MeuEnumerador.Enumerador1;
Attribute atributo = meuEnumerador.ObterAtributoDoTipo<DescriptionAttribute>();
And the extension ObterDescrição will actually return me to Description and for this it uses the other extension to fetch the attribute. Example usage:
var meuEnumerador = MeuEnumerador.Enumerador1;
string descricao = meuEnumerador.ObterDescricao();
I looked in various places on how to do it, and that was the best solution I found, if anyone knows other ways to do this, share it on the answers.
just use getDescription:
var teste = MeuEnumerador.GetDescription();
