public partial class Form1 : Form
public Form1()
InitializeComponent();
ChromiumWebBrowser WebBrowser;
private void Form1_Load(object sender, EventArgs e)
var settings = new CefSettings()
UserAgent = "Mozilla/5.0 (Linux; Android 5.0; SM-G900P Build/LRX21T) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Mobile Safari/537.36",
//Perform dependency check to make sure all relevant resources are in our output directory.
Cef.Initialize(settings, performDependencyCheck: true, browserProcessHandler: null);
// cefsharp提供的浏览器控件，一般用它充满窗口就搞定了
WebBrowser = new ChromiumWebBrowser("http://www.163.com")
// 填充整个父控件
Dock = DockStyle.Fill
WebBrowser.FrameLoadEnd += new EventHandler<FrameLoadEndEventArgs>(FrameEndFunc);
// 添加到窗口的控件列表中
this.panel1.Controls.Add(WebBrowser);
private void FrameEndFunc(object sender, FrameLoadEndEventArgs e)
MessageBox.Show("加载完毕");
this.BeginInvoke(new Action(() =>
String html = WebBrowser.GetSourceAsync().Result;
richTextBox1.Text = html;
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
// 结束时要销毁
Cef.Shutdown();
效果：可以加载很多原生webbrowser不能加载的内容 可以适应iframe
2、执行页面中的js函数
测试的js代码
<button type="button" onclick="test(1,2)">测试按钮</button>
</body>
<script type="text/javascript">
function test(a,b)
var c = testfunc(a,b);
alert(c);
function testfunc(a,b)
return a+b;
</script>
调用页面中的testfunc函数
private void button3_Click(object sender, EventArgs e)
using (StreamReader sr = new StreamReader("JavaScript1.html"))
string html = sr.ReadToEnd();
WebBrowser.LoadHtml(html, "http://testpage/");
private void button4_Click(object sender, EventArgs e)
String script = "testfunc(99,1)";
var result = this.WebBrowser.EvaluateScriptAsync(script).Result.Result;
MessageBox.Show(result.ToString());
3、常用方法
//浏览网址：
WebBrowser = new ChromiumWebBrowser("https://www.baidu.com");
WebBrowser.Load("https://www.baidu.com");
// 获取HTML(整体):
WebBrowser.GetSourceAsync().Result;
// 获取HTML(特定Frame):
WebBrowser.GetBrowser().GetFrame(“SI2_mem_index”).GetSourceAsync().Result；
//执行网页上的JavaScript:
ExecuteJavaScriptAsync("document.getElementById('username').onkeydown();");
//模拟左键点击:
WebBrowser.GetBrowser().GetHost().SendMouseClickEvent(x, y, MouseButtonType.Left, false, 1, CefEventFlags.None);
Thread.Sleep(50);
WebBrowser.GetBrowser().GetHost().SendMouseClickEvent(x, y, MouseButtonType.Left, true, 1, CefEventFlags.None);
