DisplayName attribute from Resources

Question

I have a localized application  and I am wondering if it is possible to have the DisplayName for a certain model property set from a Resource   I d like to do something like this   public class MyModel      Required     DisplayName Resources Resources labelForName     public string name  get  set        But I can t to it  as the compiler says   An attribute argument must be a constant expression  typeof expression or array creation expression of an attribute parameter type      Are there any workarounds  I am outputting labels manually  but I need these for the validator output

I got Gunders answer working with my App_GlobalResources by choosing the resources properties and switch "Custom Tool" to "PublicResXFileCodeGenerator" and build action to "Embedded Resource". Please observe Gunders comment below.

Works like a charm :)

How about writing a custom attribute   public class LocalizedDisplayNameAttribute  DisplayNameAttribute       public LocalizedDisplayNameAttribute string resourceId             base GetMessageFromResource resourceId                private static string GetMessageFromResource string resourceId                   TODO  Return the string from the resource file           which could be used like this   public class MyModel         Required       LocalizedDisplayName  labelForName        public string Name   get  set

If you use MVC 3 and  NET 4  you can use the new Display attribute in the System ComponentModel DataAnnotations namespace  This attribute replaces the DisplayName attribute and provides much more functionality  including localization support   In your case  you would use it like this   public class MyModel        Required       Display Name    labelForName   ResourceType   typeof Resources Resources        public string name  get  set        As a side note  this attribute will not work with resources inside App GlobalResources or App LocalResources  This has to do with the custom tool  GlobalResourceProxyGenerator  these resources use  Instead make sure your resource file is set to  Embedded resource  and use the  ResXFileCodeGenerator  custom tool     As a further side note  you shouldn t be using App GlobalResources or App LocalResources with MVC  You can read more about why this is the case here

public class Person          Before C  6 0      Display Name    Age   ResourceType   typeof Testi18n Resource        public string Age   get  set            After C  6 0         Display Name   nameof Resource Age   ResourceType   typeof Resource         Define ResourceType of the attribute so it looks for a resource Define Name of the attribute which is used for the key of resource  after C  6 0  you can use nameof for strong typed support instead of hard coding the key  Set the culture of current thread in the controller    Resource Culture   CultureInfo GetCultureInfo  zh-CN      Set the accessibility of the resource to public Display the label in cshtml like this    Html DisplayNameFor model   gt  model Age

If you open your resource file and change the access modifier to public or internal it will generate a class from your resource file which allows you to create strongly typed resource references     Which means you can do something like this instead  using C  6 0   Then you dont have to remember if firstname was lowercased or camelcased  And you can see if other properties use the same resource value with a find all references    Display Name   nameof PropertyNames FirstName   ResourceType   typeof PropertyNames    public string FirstName   get  set
