如何为asp.net mvc ValidationMessageFor创建可重用的解决方案

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

public static class HtmlHelperExtensions
{
    public static MvcHtmlString ReusableValidationMessageFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression)
    {
        var propertyName = ExpressionHelper.GetExpressionText(expression);
        var modelState = htmlHelper.ViewData.ModelState;
        
        if (modelState.ContainsKey(propertyName) && modelState[propertyName].Errors.Count > 0)
        {
            var error = modelState[propertyName].Errors[0].ErrorMessage;
            return MvcHtmlString.Create($"<span class='error'>{error}</span>");
        }
        
        return MvcHtmlString.Empty;
    }
}

@using YourProjectNamespace.Extensions

@model YourProjectNamespace.Models.YourModel

@Html.ReusableValidationMessageFor(m => m.YourProperty)
