如何在asp.net内核中扩展"DisplayNameFor“以显示全文？

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

public static class HtmlHelperExtensions
{
    public static MvcHtmlString FullDisplayNameFor<TModel, TValue>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TValue>> expression)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        var displayName = metadata.DisplayName ?? metadata.PropertyName;

        return MvcHtmlString.Create(displayName);
    }
}

@model YourModelType

@Html.FullDisplayNameFor(model => model.YourProperty)
