【WPF嵌套vue3】5. .netcore 6.0 WPF 使用CefSharp_cefsharp wpf

CefSharp

CEF ，全称Chromium Embedded Framework ，基于谷歌 Chromium项目的开源Web Browser控件，它的主要用途是嵌入了第三方应用以实现浏览器相关的功能。例如国内的360安全浏览器的兼容模式即IE的内核，极速模式即Chromium内核；最近微软新推出的Microsoft Edge也是基于Chromium开源项目实现的

CefSharp是Cef的C#版本，让Chromium浏览器也可嵌入WinForms 中link

大家可以看个简单的简介即可，因为我都项目是WPF+CefSharp,并且我希望我的项目能在Win7上运行，所以对CefSharp的包有版本要求:

• CefSharp.Wpf.NETCore @109.1.110
• CefSharp.Common.NETCore @109.1.110
• 使用前记得将.netcore项目的运行平台都改成Windows
• 勾选 为该项目启用Windows窗体
  

创建新页面 准备嵌入Cef组件

我在这里直接创建了个UserControl
就写了简单的初始化事件、界面元素增加了Grid

<UserControl x:Class="WPF.NetCore.Startup.Control.MainBrowser"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:WPF.NetCore.Startup.Control"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800"
              xmlns:prism="http://prismlibrary.com/"
        prism:ViewModelLocator.AutoWireViewModel="True"
             xmlns:b="http://schemas.microsoft.com/xaml/behaviors" 
             >
    <b:Interaction.Triggers>
        <b:EventTrigger EventName="Loaded">
            <b:InvokeCommandAction Command="{Binding Loaded}" />
        </b:EventTrigger>
    </b:Interaction.Triggers>
    <Grid x:Name="cefWebBrowserGrid">
    </Grid>
</UserControl>

xaml.cs文件

直接复制即可

• 初始化了CefSharp的配置信息
• 将ChromiumWebBrowser 组件添加至页面的Gird元素中
• 增加了chrom插件的键盘点击事件(可不加，我增加了F5刷新及F12打开管理者调试工具)
