推荐答案

尝试执行此操作，在HTML文件中创建一个H1标签，然后将鼠标悬停在该标签上，您可以看到放置在文本框中的文本

Try this create a H1 tag in your HTML file and hover the mouse on that you can see the text placed in text box

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication1
{
    public partial class Form5 : Form
    {
        public Form5()
        {
            InitializeComponent();
            webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
        }

        void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            webBrowser1.Document.Body.MouseOver += new HtmlElementEventHandler(Body_MouseOver);
        }

        void Body_MouseOver(object sender, HtmlElementEventArgs e)
        {
            if (e.ToElement != null && e.ToElement.TagName == "H1" && e.ToElement.GetAttribute("processed") != "true")
            {
                string[] words = e.ToElement.InnerHtml.Split(' ');
                e.ToElement.InnerHtml = "";
                for (int i = 0; i < words.Length; i++)
                    e.ToElement.InnerHtml += "<span> " + words[i] + " </span>";

                foreach (HtmlElement el in e.ToElement.GetElementsByTagName("span"))
                    el.MouseOver += new HtmlElementEventHandler(e_MouseOver);

                e.ToElement.SetAttribute("processed", "true");
            }
        }

        void e_MouseOver(object sender, HtmlElementEventArgs e)
        {
            toolStripTextBox1.Text = e.ToElement.InnerText;
        }


    }
}
