合并html-tag到其他-tag

Question

我有这个方法：

 while (created < 2)
        {
      var tb = new TagBuilder("input");
            tb.MergeAttribute("id", model.QuestionId);
            tb.MergeAttribute("name", model.QuestionId);
            tb.MergeAttribute("type", "radio");
            if (model.Disabled == true)
            {
                tb.MergeAttribute("Disabled", model.Disabled.ToString());
            }
            tb.MergeAttributes(GetHtmlAttributes(model.HtmlAttributes));
            tb.AddCssClass("form-field");
            var innerText = created % 2 == 0 ? "Kvinna" : "Man";
            tb.MergeAttribute("value", innerText);
            sb.Append(tb.ToString(TagRenderMode.SelfClosing));
            var spanBuilder = new TagBuilder("span");
            spanBuilder.SetInnerText(innerText);

   This code ---> var spanBuilders = new TagBuilder("span");
            spanBuilders.MergeAttribute("id", model.QuestionId + "radio");
            spanBuilders.MergeAttribute(spanBuilder.ToString((TagRenderMode.Normal)));<--- 

            sb.Append(spanBuilder.ToString(TagRenderMode.Normal));
}

我想要做的是以某种方式合并span-tag spanbuilder并将其放入另一个标记中。while循环通过两次，因此它将创建spanbuilder的两个span-tag，我希望它们位于另一个span-tag内。有什么好方法可以做到这一点吗？

您应该为跨度标记创建一个DocFragment，然后将其附加到父标记。我建议您使用XMLDocument或XDocument来完成此操作。请参阅X Document link
