引入库：CefSharp.WinForms

using CefSharp;
    using CefSharp.WinForms;
    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;
    
    namespace 大屏Win
    {
        public partial class Form1 : Form
        {
            static string url = System.Configuration.ConfigurationManager.AppSettings["url"].ToString();//从配置文件中读取要打开的url
            static ChromiumWebBrowser chromeBrowser = null;
    
            public Form1()
            {
                InitializeComponent();
                try
                {
                    CefSettings settings = new CefSettings();
                    settings.Locale = "zh-CN";//中文环境
                    settings.AcceptLanguageList = "zh-CN";//中文环境
                    settings.CachePath = System.IO.Directory.GetCurrentDirectory()+"\\cache";//设置缓存
                    Cef.Initialize(settings);
                    chromeBrowser = new ChromiumWebBrowser(url);
                    chromeBrowser.AddressChanged += Browser_AddressChanged;//监听地址变化
                    this.Controls.Add(chromeBrowser);
                    chromeBrowser.Dock = DockStyle.Fill;
    
                    //js和cs交互
                    chromeBrowser.JavascriptObjectRepository.Settings.LegacyBindingEnabled = true;
                    chromeBrowser.JavascriptObjectRepository.Register("yfcsobj", new yfcsobj(), isAsync: true, options: BindingOptions.DefaultBinder);
    
                    chromeBrowser.ExecuteScriptAsync("refreshdata()");//c# 调用 js方法
    
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message);
                    Application.Exit();
                }
            }
            private void Browser_AddressChanged(object sender, AddressChangedEventArgs e)
            {
                //MessageBox.Show(e.Address);
            }
            private void Form1_FormClosing(object sender, FormClosingEventArgs e)
            {
                Cef.Shutdown();
            }
    
            //监听键盘按键
            private void Form1_KeyDown(object sender, KeyEventArgs e)
            {
                if (e.KeyData == Keys.F12)
                {
                    chromeBrowser.ShowDevTools();//打开调试模式
                }
            }
        }
    }

public class yfcsobj
        {
            public void test(string msg)
            {
               MessageBox.Show(msg);
            }  
            
            public void closeApp()
            {
                //彻底关闭进程
                System.Environment.Exit(0);
                Application.Exit();
            }
        }

html中使用

<html>
    <body>
    <button onclick="test()">test</button>
    <button onclick="test2()">test2</button>
    
    <script>
    function test(){
    	yfcsobj.test('test js');
    }
    function test2(){
    	yfcsobj.closeApp();
    }
    </script>
    </body>
    <html>
