Am trying to get a very simple, console app to work with localizing and TryValidateObject on my object.

I have a Student class: 

 public class Student
    {
        [Display(ResourceType = typeof(Strings), Name = @"Student_Name_DisplayName")]
        [Required]
        public string Name {get; set;}
    }

I have a public resource Strings.resx for my default language (English) with 

Key = Student_Name_DisplayName
Value = Name

I have an internal resource file Strings.es.resx for Spanish

Key = Student_Name_DisplayName
Value = Nombre

If I create a new Student object and do not set the Name property to something, I expect to see an error if I call Validator.TryValidateObject. I do.

Setting the current Culture and UI Culture to English, I get the validation error: "The Name field is required."

Setting the current Culture and UI culture to Spanish, I get the validation error: "The Nombre field is required."

Pretty close, but I'd like the rest of the message to be in Spanish as well.

I've found that doing this in Silverlight works - Silveright somehow "sees" the right language and gets me the right error. However, I have some server-side processing I'd also like to have return the proper translated string.

The full code is below: 

System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo("en");
System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("en");

Student student  = new Student();
var validationResults = new Collection<ValidationResult>();

Validator.TryValidateObject(student, new ValidationContext(student, null, null), validationResults, true);

if (validationResults.Count > 0)
  Debug.WriteLine(validationResults[0].ErrorMessage);
//produces "The Name field is required"    

validationResults.Clear(); 

System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo("es");
System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("es");

Student student2 = new Student();
Validator.TryValidateObject(student2, new ValidationContext(student2, null, null), validationResults, true);

if (validationResults.Count > 0)
  Debug.WriteLine(validationResults[0].ErrorMessage);
  //produces "The Nombre field is required"

Thoughts?

Thanks (Gracias)

You need to specify values for the localization properties of the [Required] attribute (e.g. ErrorMessageResourceName).

See http://haacked.com/archive/2009/12/11/localizing-aspnetmvc-validation.aspx

Silverlight seems to ship with all the localized resources, but the .NET framework does not.

Try installing the .NET Language Pack (for .NET 4.5: http://www.microsoft.com/en-us/download/details.aspx?id=30667)

You will need to read the property name using these lines

var context = new ValidationContext(parseResult.ProductVM, serviceProvider: null, items: null);
List<ValidationResult> validationResults = new List<ValidationResult>();
bool isValid = Validator.TryValidateObject(parseResult.ProductVM, context, validationResults, true);
if (!isValid)
{
    string memberName = validationResults.FirstOrDefault().MemberNames.FirstOrDefault();
    string displayName = GeneralHelper.GetDisplayNameByMemberName<ViewModels.ProductVM>(memberName);
    string displayNameTranslated = resourceManager.GetString(displayName, MultiLangHelper.CurrentCultureInfo);   
}

Then continue the answer here to get the translated name / the value from .resx files

**parseResult.ProductVM is my view model

**GetDisplayNameByMemberName is mentioned in my other answer in the link above

**The resourceManager

ResourceManager resourceManager = new System.Resources.ResourceManager(typeof(App_GlobalResources.Pages));
