wpf中使用cefsharp加载本地html网页并实现cs和js的交互,并且cefsharp支持any cpu

 

废话少说,直接上代码:

第一步:

第二步:

第三步:

 

第四步:

App.xaml.cs对应的代码:

using CefSharp;
using CefSharp.Wpf;
using System;
using System.IO;
using System.Reflection;
using System.Runtime.CompilerServices;
using System.Windows;

namespace CefSharpe
{
    /// 

    /// App.xaml 的交互逻辑
    /// 
    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;
        }
    }
}

以上实现的是cefsharp支持any cpu

下面实现加载本地html并且实现与js交互,对于如何下载cefsharp就不做过多说明,网上一大把

第五步:

"CefSharpe.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:CefSharpe"
        xmlns:cefSharp="clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf"
        mc:Ignorable="d"
        Title="cefSharp" >
    
        "cefsharp">
        "30" VerticalAlignment="Bottom" Click="Button_Click">调用js的方法
    

第六步:

using CefSharp;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

using System.IO;
using System.Reflection;
using System.Runtime.CompilerServices;
using CefSharp.Wpf;


namespace CefSharpe
{
    /// 

    /// MainWindow.xaml 的交互逻辑
    /// 
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
          
            InitializeComponent();
          
            CefSharpSettings.LegacyJavascriptBindingEnabled = true;
           
            this.cefsharp.Address = AppDomain.CurrentDomain.BaseDirectory+@"index.html";
            this.cefsharp.RegisterJsObject("JsObj", new CallbackObjectForJs(), new CefSharp.BindingOptions { CamelCaseJavascriptNames = false});
            //阻止默认行为
            cefsharp.MenuHandler = new MenuHandler();
        }
        public class CallbackObjectForJs
        {

            public string name = "";
            public void showTest(string msg)
            {
                MessageBox.Show(msg);
                MessageBox.Show(name);
            }
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            cefsharp.ExecuteScriptAsync("ydb1('asdadaasdasdas我是杨道波')");
        }
        public class MenuHandler : IContextMenuHandler
        {
            public void OnBeforeContextMenu(IWebBrowser browserControl, IBrowser browser, IFrame frame, IContextMenuParams parameters, IMenuModel model)
            {
                model.Clear();
            }
            public bool OnContextMenuCommand(IWebBrowser browserControl, IBrowser browser, IFrame frame, IContextMenuParams parameters, CefMenuCommand commandId, CefEventFlags eventFlags)
            {
                return false;
            }
            public void OnContextMenuDismissed(IWebBrowser browserControl, IBrowser browser, IFrame frame)
            {
            }
            public bool RunContextMenu(IWebBrowser browserControl, IBrowser browser, IFrame frame, IContextMenuParams parameters, IMenuModel model, IRunContextMenuCallback callback)
            {
                return false;
            }
        }
   

    }
   
}

第七步:

在本地项目中放入index.html

第八步:

index.html里面的内容

"en">

    "UTF-8">
    


"ydb">我是杨道波sdadsad


    
    
    
    
        
            
                
            
            
        
        
        
        
        
            
            
            
            
        
        
        
        
        
            
        
            
            
        
    

效果展示:

点击文字:

点击名为(调用js的方法)的按钮:

 

 拿走不谢.

这是要把我一个学前端逼的转行的节奏啊.
