基于.Net CEF 实现 Vue 等前端技术栈构建 Windows 窗体应用

Tip：Focus

If you have decided to work on a task, do it as well as you can. Don’t start multiple things at the same time. Do only one thing at one time. You’ll not become quicker, just you work multithreaded. If you work multithreaded you’ll become exhausted, make more errors and lose time to jump from one task to another. If you code, code. This is not only about programming, this is a general tip.

一、安装 Nuget 包

https://www.nuget.org/packages/CefSharp.WinForms

安装 CefSharp.WinForms 包后会显示 Readme.txt，

二、配置项目

<PropertyGroup Condition="'$(PlatformTarget)' == 'x64'">
  <RuntimeIdentifier Condition="'$(RuntimeIdentifier)' == ''">win-x64RuntimeIdentifier>
  <SelfContained Condition="'$(SelfContained)' == ''">falseSelfContained>
PropertyGroup>

三、加载远程网页示例

使用 ChromiumWebBrowser 加载百度首页，

// Form1.cs
using CefSharp;
using CefSharp.WinForms;
using System.Windows.Forms;
 
namespace CefWindowsFormsApp
{
    public partial class Form1 : Form
    {
        private static ChromiumWebBrowser browser;
 
        public Form1()
        {
            InitializeComponent();
            AddChromiumWebBrowser();
        }
 
        /// 
        /// Create a new instance in code or add via the designer
        /// 
        private void AddChromiumWebBrowser()
        {
            browser = new ChromiumWebBrowser("www.baidu.com");
            this.Controls.Add(browser);
        }
 
        private void Form1_Load(object sender, System.EventArgs e)
        {
            // Load a url
            browser.LoadUrl("https://www.baidu.com/");
        }
    }
}

这这个示例中，我们引入了 CefSharp 库，在 Form1 窗体中添加了浏览器控件 ChromiumWebBrowser ，并且在窗体启动时加载百度首页，

四、加载本地网页示例

首先创建一个 Vue 项目，

# 使用 Vite
cnpm create vite@latest
 
# cd vite-project
# cnpm i

接着完成前端的开发之后，打包静态资源，

npm run build

然后在 WinForm 项目下创建 Resources 文件夹，把前端打包的 dist 文件夹下的文件全部复制过来，并且文件属性设置为“嵌入的资源”，

最后通过 RegisterScheme 注册为本地资源访问，

// Form1.cs
using CefSharp;
using CefSharp.SchemeHandler;
using CefSharp.WinForms;
using System.Windows.Forms;
 
namespace CefWindowsFormsApp
{
    public partial class Form1 : Form
    {
        private static ChromiumWebBrowser browser;
 
        public Form1()
        {
            InitializeComponent();
            AddChromiumWebBrowser();
        }
 
        /// 
        /// Create a new instance in code or add via the designer
        /// 
        private void AddChromiumWebBrowser()
        {
            InitBrowser();
 
            browser = new ChromiumWebBrowser("http://cefsharp.test");
            this.Controls.Add(browser);
 
        }
 
        public static void InitBrowser()
        {
            // Pseudo code; you probably need more in your CefSettings also.
            var settings = new CefSettings();
 
            settings.RegisterScheme(new CefCustomScheme
            {
                SchemeName = "http",
                DomainName = "cefsharp.test",
                SchemeHandlerFactory = new FolderSchemeHandlerFactor
