C# WPF中嵌入Chrome浏览器

借鉴 

https://www.cnblogs.com/guxin/p/wpf-embed-html-by-cefsharp.html

搭建基本的开发环境

　　新建WPF程序

　　右击隐引用，选择管理NuGet包

　　在nuget中搜索CefSharp，其中有CefSharp.WinForms和CefSharp.Wpf，在这里应该安装CefSharp.Wpf

　　因为CefSharp不支持AnyCPU，需要VS中为项目编译平台单独指定x86和x64

　　需重启vs才可以正常运行

XAML的简单示例

<Window x:Class="Demo.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:Demo"
        xmlns:wpf="clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf"
        xmlns:cef="clr-namespace:CefSharp;assembly=CefSharp.Core"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
    <Grid>
        <wpf:ChromiumWebBrowser x:Name="Browser" Address="http://www.baidu.com"/>
    </Grid>
</Window>

　　注意使用xmlns:wpf="clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf"和xmlns:cef="clr-namespace:CefSharp;assembly=CefSharp.Core"来引入浏览器控件所在的程序集。

直接在类中实现的简单示例

 新建类OpenPageSelf.cs，用于设置让新开的链接覆盖显示在本页上

　　借鉴　　https://www.cnblogs.com/wolf-sun/p/6929728.html

　　新建OpenPageSelf类后，在webView.Address = "http://www.baidu.com";后添加webView.LifeSpanHandler = new OpenPageSelf();

using CefSharp;
using CefSharp.Wpf;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Demo1
{
    /// <summary>
    /// 在自己窗口打开链接
    /// </summary>
    internal class OpenPageSelf:ILifeSpanHandler
    {
        public bool DoClose(IWebBrowser browserControl,IBrowser browser)
        {
            return false;
        }
        public void OnAfterCreated(IWebBrowser browserControl,IBrowser browser)
        {

        }

        public void OnBeforeClose(IWebBrowser chromiumWebBrowser, IBrowser browser)
        {
            
        }

        public bool OnBeforePopup(IWebBrowser browserControl, IBrowser browser, IFrame frame, string targetUrl,
string targetFrameName, WindowOpenDisposition targetDisposition, bool userGesture, IPopupFeatures popupFeatures,
IWindowInfo windowInfo, IBrowserSettings browserSettings, ref bool noJavascriptAccess, out IWebBrowser newBrowser)
        {
            newBrowser = null;
            var chromiumWebBrowser = (ChromiumWebBrowser)browserControl;
            chromiumWebBrowser.Load(targetUrl);
            return true; //Return true to cancel the popup creation copyright by codebye.com.
        }
    }
}
