How do I display the DisplayAttribute.Description attribute value?

by

I ended up with a helper like this:

using System;
using System.Linq.Expressions;
using System.Web.Mvc;

public static class MvcHtmlHelpers
{
    public static MvcHtmlString DescriptionFor<TModel, TValue>(this HtmlHelper<TModel> self, Expression<Func<TModel, TValue>> expression)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, self.ViewData);
        var description = metadata.Description;

        return MvcHtmlString.Create(string.Format(@"<span>{0}</span>", description));
    }
}

Thanks to those who led me in the right direction. 🙂
