大家好，又见面了，我是你们的朋友全栈君。

参考：https://github.com/cefsharp/CefSharp/issues/601 https://gist.github.com/BlackBooth/19ce027c4f68c1eb4fc1144988ca6662

关键点：（1）设置CefSettings的BrowserSubprocessPath属性为对应的CefSharp.BrowserSubprocess.exe的路径；（2）在Program.cs中加载相关程序集；

将Cefsharp相关库放到bin\Debug\cefLib目录中

添加CefSharp类库引用，并把相关库的属性（复制本地）设置为false，这样VS就不会自动复制相关库到运行目录下；

修改Program.cs的代码如下，注：在Program.cs中不能引用相关的Cefsharp相关库，否则会加载Cefsharp程序集失败；

static class Program
    {
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            AppDomain.CurrentDomain.AssemblyResolve += OnResolveAssembly;
            CefSettingClass.InitializeCefSetting();
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new MainForm());
        }

        //解析程序集失败，会加载对应的程序集
        private static Assembly OnResolveAssembly(object sender, ResolveEventArgs args)
        {
            Assembly executingAssembly = Assembly.GetExecutingAssembly();
            AssemblyName assemblyName = new AssemblyName(args.Name);

            var assemblyAllName = assemblyName.Name + ".dll";
            //加载CefSharp相关库
            if (args.Name.StartsWith("CefSharp"))
            {
                string assemblyPath = Path.Combine(Application.StartupPath, CefSettingClass.CefLibName, assemblyAllName);
                return File.Exists(assemblyPath) ? Assembly.LoadFile(assemblyPath) : null;
            }
            //判断程序集的区域性
            if (!assemblyName.CultureInfo.Equals(CultureInfo.InvariantCulture))
            {
                assemblyAllName = string.Format(@"{0}\{1}", assemblyName.CultureInfo, assemblyAllName);
            }

            using (Stream stream = executingAssembly.GetManifestResourceStream(assemblyAllName))
            {
                if (stream == null) return null;

                var assemblyRawBytes = new byte[stream.Length];
                stream.Read(assemblyRawBytes, 0, assemblyRawBytes.Length);
                return Assembly.Load(assemblyRawBytes);
            }
        }

    }

新增CefSettingClass类，用于初始化CefSharp;

class CefSettingClass
    {
        public const string CefLibName = "cefLib"; //cef目录名称

        /// <summary>
        /// 初始化CEF的配置
        /// </summary>
        public static void InitializeCefSetting()
        {
            string appPath = Application.StartupPath;
            CefSettings settings = new CefSettings
            {
                Locale = "zh-CN", //中文
                BrowserSubprocessPath = Path.Combine(appPath, CefLibName, "CefSharp.BrowserSubprocess.exe"), //设置浏览器子程序启动路径
            };
            Cef.Initialize(settings);
        }

    }

主窗口代码如下，初始化并添加浏览器控件到主窗口中：

public partial class MainForm : Form
    {
        private ChromiumWebBrowser browser;

        public MainForm()
        {
            InitializeComponent();
        }

        private void MainForm_Load(object sender, EventArgs e)
        {
            browser = new ChromiumWebBrowser("https://www.baidu.com")
            {
                Dock = DockStyle.Fill
            };
            this.Controls.Add(browser);
            this.Closing += OnClosing;
        }

        private void OnClosing(object sender, CancelEventArgs e)
        {
            Cef.Shutdown();
        }
    }
