DisplayAttribute name with variable, Dynamic DisplayName

I wonder if this is possible or something with this effect.

public class MyModel
{
    public string Name { get; set; }

    [Display(Name = String.Format("This is [0] phone number", Name)]
    public string PhoneNumber { get; set; }
}

I am talking about DisplayName with a variable in it that is not static, and possibly based on models of other properties. Is this possible anyway?

This is not possible because the arguments specified for attribute parameters must be constant values ​​(instinctively, because there is no context in relation to anything else and may not necessarily be resolved at compile time (which is a requirement)). From the C # specification (3.0) §17.2:

An expression Eis an expression of an argument attribute if all of the following statements are true:

  • E - (§17.1.3).
  • E :
    • .
    • System.Type.
    • --.
