Question

我有这段代码

<div class="round-3-top">
  <div class="round-2-top">
    <div class="round-1-top"></div>
    <div class="round-1-bottom"></div>
  </div>

  <div class="round-2-bottom">
    <div class="round-1-top"></div>
    <div class="round-1-bottom"></div>
  </div>
</div>

<div class="round-3-bottom">
  <div class="round-2-top">
    <div class="round-1-top"></div>
    <div class="round-1-bottom"></div>
  </div>

  <div class="round-2-bottom">
    <div class="round-1-top"></div>
    <div class="round-1-bottom"></div>
  </div>
</div>

但我想动态生成，我是怎么做到的？

例：我有4轮，这将是生成的代码

    <div class="round-4-top">
      <div class="round-3-top">
          <div class="round-2-top">
            <div class="round-1-top"></div>
            <div class="round-1-bottom"></div>
          </div>

          <div class="round-2-bottom">
            <div class="round-1-top"></div>
            <div class="round-1-bottom"></div>
          </div>
        </div>
    <div class="round-3-bottom">
      <div class="round-2-top">
        <div class="round-1-top"></div>
        <div class="round-1-bottom"></div>
      </div>

      <div class="round-2-bottom">
        <div class="round-1-top"></div>
        <div class="round-1-bottom"></div>
      </div>
    </div>
</div>

 <div class="round-4-bottom">
      <div class="round-3-top">
          <div class="round-2-top">
            <div class="round-1-top"></div>
            <div class="round-1-bottom"></div>
          </div>

          <div class="round-2-bottom">
            <div class="round-1-top"></div>
            <div class="round-1-bottom"></div>
          </div>
        </div>
    <div class="round-3-bottom">
      <div class="round-2-top">
        <div class="round-1-top"></div>
        <div class="round-1-bottom"></div>
      </div>

      <div class="round-2-bottom">
        <div class="round-1-top"></div>
        <div class="round-1-bottom"></div>
      </div>
    </div>
</div>

我尝试在MVC C＃中使用TagBuilder，但我不能这样做。应该发生的是，如果你是3轮，添加他应该进入每个div内部就像上面的例子。我知道如何开发它？

您可以使用返回MVCHtmlString的MVC Helpers执行此操作。助手类如下。递归是完美的。辅助类

public static class Helpers
{
    public static MvcHtmlString GetStructure(int size)
    {
        return MvcHtmlString.Create(GetRecursiveStructure(size));
    }

    private static string GetRecursiveStructure(int size)
    {
        if (size == 0)
        {
            return "";
        }
        else
        {
            TagBuilder topTag = new TagBuilder("div");
            topTag.AddCssClass(string.Format("round-{0}-top", size));
            topTag.InnerHtml = GetRecursiveStructure(size - 1);
            TagBuilder bottomTag = new TagBuilder("div");
            bottomTag.AddCssClass(string.Format("round-{0}-bottom", size));
            bottomTag.InnerHtml = GetRecursiveStructure(size - 1);
            return topTag.ToString() + bottomTag.ToString();
        }
    }

}

在您看来，请执行以下操作：

@Helpers.GetStructure(4)

循环追加div并重复
