How to localize Attribute values?

[aloksharma1]

Hello, Do you have any example on localizing DisplayAttribute or similar? i tried creating my own localized attribute but it seems you can't proper DI into attribute classes, here is what i tried:

public sealed class LocalizedDisplayAttribute : Attribute
    {
        protected IJsonStringLocalizer StringLocalizer;

        public LocalizedDisplayAttribute(string displayName) 
        {
            StringLocalizer = HttpContextHelper.HttpContext.RequestServices.GetService<IJsonStringLocalizer>();
            DisplayName = displayName;            
        }

        public string DisplayName
        {
            get
            {
                return StringLocalizer[DisplayName];
            }
            set
            {

            }
        }
    }

unfortunately it always returns null service to me, tried using httpcontextaccessor, direct injection and what not..
if anyone have done this already please help.

Hi,

if as DisplayAttribute you mean "DataAnnotation" you should only follow the microsoft guidelines to activate it.
For custom attribute you should inject the IJsonStringLocalizer like in your exemple.

I will investigate more next week. If you already have a solution, don't forgot to share it in this thread
