篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了CefSharp For WPF基本使用相关的知识，希望对你有一定的参考价值。

Nuget引用

CefSharp.Wpf
CefSharp.Common
cef.redist.x64
cef.redist.x86

直接搜索安装CefSharp.Wpf即可，因为CefSharp.Wpf依赖于其他三个包，所以会自动安装四个包

先更改设置

指定特定的平台，x64或者x86，默认是Any CPU
不进行配置的话，CefSharp是不支持Any CPU的

WPF写法

xmlns:cefSharpWPF="clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf"
<cefSharpWPF:ChromiumWebBrowser Address="url"></cefSharpWPF:ChromiumWebBrowser>

Any CPU的支持

using System.Windows;
using System;
using System.Runtime.CompilerServices;
using CefSharp;
using System.IO;
using System.Reflection;
using System.Windows.Threading;
using CefSharpWpfDemo.Log;

namespace CefSharpWpfDemo
{
    /// <summary>
    /// Interaction logic for App.xaml
    /// </summary>
    public partial class App : Application
    {
        public App()
        {
            // Add Custom assembly resolver
            AppDomain.CurrentDomain.AssemblyResolve += Resolver;
            //Any CefSharp references have to be in another method with NonInlining
            // attribute so the assembly rolver has time to do it‘s thing.
            InitializeCefSharp();
        }

        [MethodImpl(MethodImplOptions.NoInlining)]
        private static void InitializeCefSharp()
        {
            var settings = new CefSettings();

            // Set BrowserSubProcessPath based on app bitness at runtime
            settings.BrowserSubprocessPath = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase,
                                                   Environment.Is64BitProcess ? "x64" : "x86",
                                                   "CefSharp.BrowserSubprocess.exe");

            // Make sure you set performDependencyCheck false
            Cef.Initialize(settings, performDependencyCheck: false, browserProcessHandler: null);
        }

        // Will attempt to load missing assembly from either x86 or x64 subdir
        // Required by CefSharp to load the unmanaged dependencies when running using AnyCPU
        private static Assembly Resolver(object sender, ResolveEventArgs args)
        {
            if (args.Name.StartsWith("CefSharp"))
            {
                string assemblyName = args.Name.Split(new[] { ‘,‘ }, 2)[0] + ".dll";
                string archSpecificPath = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase,
                                                       Environment.Is64BitProcess ? "x64" : "x86",
                                                       assemblyName);

                return File.Exists(archSpecificPath)
                           ? Assembly.LoadFile(archSpecificPath)
                           : null;
            }

            return null;
