c# - 如何在后端获取 HtmlControl 对象的 HTML

Question

我有一小段像这样的 C# 代码:

HtmlGenericControl titleH3 = new HtmlGenericControl("h3");
titleH3.Attributes.Add("class", "accordion");

HtmlAnchor titleAnchor = new HtmlAnchor();
titleAnchor.HRef = "#";
titleAnchor.InnerText = "Foo Bar";
titleH3.Controls.Add(titleAnchor);

我想要的是一种返回如下所示的字符串的方法:

<h3 class="accordion"><a href="#">Foo Bar</a></h3>

有什么想法或建议吗？

Answer 1

这是我过去用来提前获取控件呈现的 HTML 的方法(确保包含 System.IO):

protected string ControlToHtml(Control c)
{
    StringWriter sw = new StringWriter();
    HtmlTextWriter htmlWriter = new HtmlTextWriter(sw);
    c.RenderControl(htmlWriter);
    return sw.ToString();
}

为你的测试用例返回这个:

<h3 class="accordion"><a href="#">Foo Bar</a></h3>
