public static class MyLabelExtensions
{
    public static MvcHtmlString Label(this HtmlHelper htmlHelper,string forName,string labelText)
    {
        return Label(htmlHelper,forName,labelText,(object) null);
    }

    public static MvcHtmlString Label(this HtmlHelper htmlHelper,string labelText,object htmlAttributes)
    {
        return Label(htmlHelper,new RouteValueDictionary(htmlAttributes));
    }
    public static MvcHtmlString Label(this HtmlHelper htmlHelper,IDictionary<string,object> htmlAttributes)
    {
        var tagBuilder = new TagBuilder("label");
        tagBuilder.MergeAttributes(htmlAttributes);
        tagBuilder.MergeAttribute("for",forName.Replace(".",tagBuilder.IdAttributeDotReplacement),true);
        tagBuilder.SetInnerText(labelText);
        return MvcHtmlString.Create(tagBuilder.ToString(TagRenderMode.Normal));
    }

    public static MvcHtmlString LabelFor<TModel,TProperty>(this HtmlHelper<TModel> htmlHelper,Expression<Func<TModel,TProperty>> expression,string labelText)
    {
        return LabelFor(htmlHelper,expression,(object) null);
    }
    public static MvcHtmlString LabelFor<TModel,object htmlAttributes)
    {
        return LabelFor(htmlHelper,new RouteValueDictionary(htmlAttributes));
    }
    public static MvcHtmlString LabelFor<TModel,object> htmlAttributes)
    {
        string inputName = ExpressionHelper.GetExpressionText(expression);
        return htmlHelper.Label(inputName,htmlAttributes);
    }
}

我用“强类型”资源使用它们：

<%= Html.LabelFor(m=>m.NickName,UserStrings.NickName) %>

希望有帮助…
