asp.net-mvc – 我能改变MVC中LabelFor渲染的方式吗？

public static class LabelExtensions {
    [SuppressMessage("Microsoft.Design","CA1006:DoNotNestGenericTypesInMemberSignatures",Justification = "This is an appropriate nesting of generic types")]
    public static MvcHtmlString SmartLabelFor<TModel,TValue>(this HtmlHelper<TModel> html,Expression<Func<TModel,TValue>> expression) {
        return LabelHelper(html,ModelMetadata.FromLambdaExpression(expression,html.ViewData),ExpressionHelper.GetExpressionText(expression));
    }

    internal static MvcHtmlString LabelHelper(HtmlHelper html,ModelMetadata metadata,string htmlFieldName) {
        string labelText = metadata.DisplayName ?? metadata.PropertyName ?? htmlFieldName.Split('.').Last();
        if (String.IsNullOrEmpty(labelText)) {
            return MvcHtmlString.Empty;
        }

        // uncomment if want * for required field
        //if (metadata.IsRequired) labelText = labelText + " *";
        labelText = labelText + ":";

        TagBuilder tag = new TagBuilder("label");
        tag.Attributes.Add("for",html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldId(htmlFieldName));
        tag.SetInnerText(labelText);
        return MvcHtmlString.Create(tag.ToString(TagRenderMode.Normal));
    }
}

要使用它：

<%:Html.SmartLabelFor(m => m.FirstName)%>

它将呈现：

<label for="FirstName">First Name:</label>

或者,如果您取消注释所需的字段*

<label for="FirstName">First Name *:</label>
