HtmlElementCollection childDivs = curElement.Children; foreach (HtmlElement childElement in childDivs) { // ..and check the TagName for "strong" if (string.Compare(childElement.TagName, "strong", true) == 0) { MessageBox.Show(childElement.InnerText); } } }} 这篇关于如何阅读子元素“strong”跨度？ C＃的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
