displayname attribute vs display attribute

Question

What is difference between DisplayName attribute and Display attribute in ASP NET MVC

User · Answer

DisplayName sets the DisplayName in the model metadata  For example    DisplayName  foo    public string MyProperty   get  set      and if you use in your view the following    Html LabelFor x   gt  x MyProperty    it would generate    lt label for  MyProperty  gt foo lt  label gt    Display does the same  but also allows you to set other metadata properties such as Name  Description       Brad Wilson has a nice blog post covering those attributes

They both give you the same results but the key difference I see is that you cannot specify a ResourceType in DisplayName attribute  For an example in MVC 2  you had to subclass the DisplayName attribute to provide resource via localization  Display attribute  new in MVC3 and  NET4  supports ResourceType overload as an  out of the box  property

I think the current answers are neglecting to highlight the actual important and significant differences and what that means for the intended usage  While they might both work in certain situations because the implementer built in support for both  they have different usage scenarios  Both can annotate properties and methods but here are some important differences   DisplayAttribute   defined in the System ComponentModel DataAnnotations namespace in the System ComponentModel DataAnnotations dll assembly can be used on parameters and fields lets you set additional properties like Description or ShortName can be localized with resources   DisplayNameAttribute   DisplayName is in the System ComponentModel namespace in System dll can be used on classes and events cannot be localized with resources   The assembly and namespace speaks to the intended usage and localization support is the big kicker  DisplayNameAttribute has been around since  NET 2 and seems to have been intended more for naming of developer components and properties in the legacy property grid  not so much for things visible to end users that may need localization and such   DisplayAttribute was introduced later in  NET 4 and seems to be designed specifically for labeling members of data classes that will be end-user visible  so it is more suitable for DTOs  entities  and other things of that sort  I find it rather unfortunate that they limited it so it can t be used on classes though   EDIT  Looks like latest  NET Core source allows DisplayAttribute to be used on classes now as well

Perhaps this is specific to  net core  I found DisplayName would not work but Display Name      does   This may save someone else the troubleshooting involved       using statements using System  using System ComponentModel DataAnnotations     needed for Display annotation using System ComponentModel     needed for DisplayName annotation  public class Whatever         Property      Display Name   Release Date        public DateTime ReleaseDate   get  set          cshtml file  Html DisplayNameFor model   gt  model ReleaseDate
