Get [DisplayName] attribute of a property in strongly-typed way

Question

Good day!

I\'ve such method to get [DisplayName] attribute value of a property (which is attached directly or using [MetadataType] attribut

Answer 1

@Buildstarted Answer works but i wanted to get the DisplayName by property name rather using linq expression so i did a little change that will save your time

public static string GetDisplayNameByMemberName(string memberName)
    {
        Type type = typeof(TModel);
        string propertyName = memberName;

        DisplayAttribute attr;
        attr = (DisplayAttribute)type.GetProperty(propertyName).GetCustomAttributes(typeof(DisplayAttribute), true).SingleOrDefault();

        //Look for [MetadataType] attribute in type hierarchy
        //http://stackoverflow.com/questions/1910532/attribute-isdefined-doesnt-see-attributes-applied-with-metadatatype-class
        if (attr == null)
            {
                MetadataTypeAttribute metadataType = (MetadataTypeAttribute)type.GetCustomAttributes(typeof(MetadataTypeAttribute), true).FirstOrDefault();
                if (metadataType != null)
                {
                    var property = metadataType.MetadataClassType.GetProperty(propertyName);
                    if (property != null)
                    {
                        attr = (DisplayAttribute)property.GetCustomAttributes(typeof(DisplayNameAttribute), true).SingleOrDefault();
                    }
                }
            }
        return (attr != null) ? attr.Name : String.Empty;
    }

I also wanted to get the localized value in the resources (.resx files) so :

string displayName = GeneralHelper.GetDisplayNameByMemberName(memberName);
string displayNameTranslated = resourceManager.GetString(displayName, MultiLangHelper.CurrentCultureInfo);

This is a helper function i made to return an object of type "CultureInfo", create a culture info of some language or pass the current one

//MultiLangHelper.CurrentCultureInfo
return System.Threading.Thread.CurrentThread.CurrentCulture;
