首先先介绍下使用“Xilium.CefGlue”来在Winform中嵌入Chrome浏览器内核程序

1、新建项目（把下图的这一大串的dll文件放入到你的Debug或者Release文件夹中，稍后我会把整个项目共享出来）

2、添加项目引用

3、在应用程序入口点写入如下代码

 
   CefRuntime.Load();
            var mainArgs = new CefMainArgs(new string[] { });
            var exitCode = CefRuntime.ExecuteProcess(mainArgs, null);
            if (exitCode != -1)
                return;
            var settings = new CefSettings
            {
                SingleProcess = false,
                MultiThreadedMessageLoop = true,
                LogSeverity = CefLogSeverity.Disable,
                Locale = "zh-CN"
            };
            CefRuntime.Initialize(mainArgs, settings, null);
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            if (!settings.MultiThreadedMessageLoop)
            {
                Application.Idle += (sender, e) => { CefRuntime.DoMessageLoopWork(); };
            }
            Application.Run(new Main());  CefRuntime.Shutdown();

4、因为对代码进行了封装，在这里不做过多解释了，调用代码如下

 
   BsControl Browser;
        private void Main_Load(object sender, EventArgs e)
        {
            Browser = new BsControl(this);
        }
 
        /// <summary>
        /// 前台主页跳转
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void Pb_Home_Click(object sender, EventArgs e)
        {
            Browser.LoadUrl("http://blog.amtemai.com/");
        }

5、BsControl的封装如下

 
  public partial class BsControl
    {
        CefBrowser bs;
        Control parent;
        Form _form;
        public BsControl(Form form)
        {
            _form = form;
            parent = ((Control)form.Controls.Find("BrowserContainer", true)[0]);
            TextBox AddressControl = ((TextBox)form.Controls.Find("Txt_Address", true)[0]);
            var cwi = CefWindowInfo.Create();
            cwi.SetAsChild(parent.Handle, new CefRectangle(0, 0, parent.Width, parent.Height));
            var bc = new BsClient();
            bc.OnCreated += bc_OnCreated;
            bc.OnTitleChanged += (s, e) =>
            {
                form.BeginInvoke(new Action(() =>
                {
                    form.Text = ((TitleChangedEventArgs)e).Title+"IT小马";
                }));
            };
            bc.OnAddressChanged += (s, e) =>
            {
                form.BeginInvoke(new Action(() =>
                {
                    AddressControl.Text = ((AddressChangedEventArgs)e).Address;
                }));
            };
            bc.OnStatusMessaged += (s, e) =>
            {
                form.BeginInvoke(new Action(() =>
                {
 
                }));
            };
            bc.OnLoadingStateChanged += (s, e) =>
            {
                form.BeginInvoke(new Action(() =>
                {
                    LoadingStateChangedEventArgs loadingstate = ((LoadingStateChangedEventArgs)e);
                    if (loadingstate.IsLoading)
                    {
                        ((PictureBox)form.Controls.Find("Pb_Refresh", true)[0]).Image = Properties.Resources.appbar_close;
                    }
                    else
                    {
                        ((PictureBox)form.Controls.Find("Pb_Refresh", true)[0]).Image = Properties.Resources.appbar_refresh;
                    }
                    if (CanGoForWard())
                    {
                        ((PictureBox)form.Controls.Find("Pb_Right", true)[0]).Enabled = true;
                        ((PictureBox)form.Controls.Find("Pb_Right", true)[0]).BackColor = Color.Transparent;
                    }
                    else
                    {
                        ((PictureBox)form.Controls.Find("Pb_Right", true)[0]).Enabled = false;
                        ((PictureBox)form.Controls.Find("Pb_Right", true)[0]).BackColor = Color.LightGray;
                    }
                    if (CanGoBack())
                    {
                        ((PictureBox)form.Controls.Find("Pb_Left", true)[0]).Enabled = true;
                        ((PictureBox)form.Controls.Find("Pb_Left", true)[0]).BackColor = Color.Transparent;

                    }
                }));
            };
            var bs = new CefBrowserSettings() { };
            CefBrowserHost.CreateBrowser(cwi, bc, bs, "http://blog.amtemai.com/");
            parent.SizeChanged += parent_SizeChanged;
            AddressControl.Text = "http://blog.amtemai.com/";
        }
