string thing = ComparaSave.Resources.Message.EmailAdrRequired;
[Required(ErrorMessage = thing)] <---- The problem!!
[DataType(DataType.EmailAddress)]
[Display(Name = "Email Address")]
[StringLength(100)]
[EmailAddress]
public string Email { get; set; }
Throws the error:
An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type.
How can I read a resource file into an attribute such as this?
You need to use :
[Required(ErrorMessageResourceName= "FullNameRequired", ErrorMessageResourceType = typeof(MyResource)]
ErrorMessage is for string only.
