c# - DataAnnotations: read out the Name property in code -

i have decorated following enum display dataannotation attributes:

public enum requiredoptions {     [display(name="optional",description ="optional")]     optional,     [display(name="not used",description ="not used")]     notused,     [display(name="required",description ="required")]     required } 

i'd read out name value of display attribute given enum value in code. how do this?

    public static string displayrequiredoptionname(requiredoptions opt)     {         // return value of name display attribute opt     } 

well, after doing digging in mvc source code (see src\system.web.mvc\html\selectextensions.cs, see getdisplayname()), here's got work:

    public static string getenumdisplayname<t>(t enuminstance)     {         return getdisplayname(enuminstance.gettype().getfield(enuminstance.tostring()));     }      private static string getdisplayname(fieldinfo field)     {         displayattribute display = field.getcustomattribute<displayattribute>(inherit: false);         if (display != null)         {             string name = display.getname();             if (!string.isnullorempty(name))             {                 return name;             }         }          return field.name;     }
