CefSharp简单来说就是一款.Net编写的浏览器包,方便你在Winform和WPF中内嵌的Chrome浏览器组件。

本文使用版本cefsharp/71
这块安装使用没有想象的那么简单,比较坑爹,各种修改配置,按照官网的A配置方案没有搞定,按照B配置方案勉强部署成功(VS2013/VS2017)!对于外文不好的我,看着英文文档脑壳疼。老外给的闭坑指南,但是感觉没有啥卵用。下面就介绍一下B方案安装部署的过程吧,A方案我就不讲了,想看的请去上面的官网查看。

CefSharp
,添加CefSharp.WinForm
,CefSharp.Winform依赖好几个包,这块选择这一个安装就可以了,NuGet会自动帮你把其他依赖的包一并下载好的。官方文档建议
:安装完NuGet包之后,关闭vs然后重新打开,避免VS自带的智能感知引用有问题在代码中引用相应的dll
using CefSharp; using CefSharp.WinForms;
完整示例:
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using CefSharp; using CefSharp.WinForms; namespace embebbedChromium { public partial class Form1 : Form { public ChromiumWebBrowser chromeBrowser; public Form1() { InitializeComponent(); // Start the browser after initialize global component InitializeChromium(); } private void Form1_Load(object sender, EventArgs e) { } //初始化浏览器并启动 public void InitializeChromium() { CefSettings settings = new CefSettings(); // Initialize cef with the provided settings Cef.Initialize(settings); // Create a browser component chromeBrowser = new ChromiumWebBrowser("https://www.baidu.com"); // Add it to the form and fill it to the form window. this.Controls.Add(chromeBrowser); chromeBrowser.Dock = DockStyle.Fill; } //窗体关闭时,记得停止浏览器 private void Form1_FormClosing(object sender, FormClosingEventArgs e) { Cef.Shutdown(); } } }
这块参考官方文档:传送门,做了部分内容的完善,这块我理解的就是提供了一个js调用C#类方法的一个示例。
下载Bootstrap相关的文件,传送门
将下载好的Bootstrap文件夹复制拷贝到你的VS项目中,并添加html文件夹,在里面新建一个index.html
文件,具体如下图所示:
html文件内容参考这里:传送门,网页下方有示例,也有模板可以下载。
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags --> <title>Bootstrap 101 Template</title> <!-- Bootstrap --> <link href="css/bootstrap.min.css" rel="stylesheet"> <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries --> <!-- WARNING: Respond.js doesn't work if you view the page via file:// --> <!--[if lt IE 9]> <script src="https://oss.maxcdn.com/html5shiv/3.7.3/html5shiv.min.js"></script> <script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"></script> <![endif]--> </head> <body> <h1>Hello, world!</h1> <!-- jQuery (necessary for Bootstrap's JavaScript plugins) --> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script> <!-- Include all compiled plugins (below), or include individual files as needed --> <script src="js/bootstrap.min.js"></script> </body> </html>
将上面的css、fonts、html、js文件夹里的文件全部选中
—》然后点击鼠标右键,选中属性
—》设置始终复制
新建一个类CefCustomObject,用来让js调用C#中类的方法,具体代码如下:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using CefSharp; using CefSharp.WinForms; using System.Diagnostics; namespace embebbedChromium { class CefCustomObject { // Declare a local instance of chromium and the main form in order to execute things from here in the main thread private static ChromiumWebBrowser _instanceBrowser = null; // The form class needs to be changed according to yours private static Form1 _instanceMainForm = null; public CefCustomObject(ChromiumWebBrowser originalBrowser, Form1 mainForm) { _instanceBrowser = originalBrowser; _instanceMainForm = mainForm; } public void showDevTools() { _instanceBrowser.ShowDevTools(); } public void opencmd() { ProcessStartInfo start = new ProcessStartInfo("cmd.exe", "/c pause"); Process.Start(start); } } }
修改Form1窗体的代码
using System; using System.IO; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using CefSharp; using CefSharp.WinForms; using System.Runtime.InteropServices; namespace embebbedChromium { public partial class Form1 : Form { public ChromiumWebBrowser chromeBrowser; public Form1() { InitializeComponent(); // Start the browser after initialize global component InitializeChromium(); //需要添加此句代码,否则下面执行会报错 CefSharpSettings.LegacyJavascriptBindingEnabled = true; // Register an object in javascript named "cefCustomObject" with function of the CefCustomObject class :3 chromeBrowser.RegisterJsObject("cefCustomObject", new CefCustomObject(chromeBrowser, this)); } private void Form1_Load(object sender, EventArgs e) { //此句代码执行有错,官网示例的跑不起来 //chromeBrowser.ShowDevTools(); } public void InitializeChromium() { CefSettings settings = new CefSettings(); // Note that if you get an error or a white screen, you may be doing something wrong ! // Try to load a local file that you're sure that exists and give the complete path instead to test // for example, replace page with a direct path instead : // String page = @"C:\Users\SDkCarlos\Desktop\afolder\index.html"; String page = string.Format(@"{0}\html-resources\html\index.html", Application.StartupPath); //String page = @"C:\Users\SDkCarlos\Desktop\artyom-HOMEPAGE\index.html"; if (!File.Exists(page)) { MessageBox.Show("Error The html file doesn't exists : "+page); } // Initialize cef with the provided settings Cef.Initialize(settings); // Create a browser component chromeBrowser = new ChromiumWebBrowser(page); // Add it to the form and fill it to the form window. this.Controls.Add(chromeBrowser); chromeBrowser.Dock = DockStyle.Fill; // Allow the use of local resources in the browser BrowserSettings browserSettings = new BrowserSettings(); browserSettings.FileAccessFromFileUrls = CefState.Enabled; browserSettings.UniversalAccessFromFileUrls = CefState.Enabled; chromeBrowser.BrowserSettings = browserSettings; } private void Form1_FormClosing(object sender, FormClosingEventArgs e) { Cef.Shutdown(); } } }
