初始化

<!--浏览器-->
<cefSharpWPF:ChromiumWebBrowser Name="webBrowser" 
                                Grid.Row="0" >
</cefSharpWPF:ChromiumWebBrowser>

public MainWindow()
{
    InitializeComponent();

    //在js里面注册对象bound，然后用该对象调用C#方法
    webBrowser.RegisterAsyncJsObject("bound", new BoundObject(this), BindingOptions.DefaultBinder); //Use the default binder to serialize values into complex objects
}

BoundObject.cs

public class BoundObject
{
    private Window mainWindow { get; set; }
    public BoundObject(Window _mainWindow)
    {
        mainWindow = _mainWindow;
    }

    /// <summary>
    /// 打开exe文件
    /// </summary>
    public void OpenFile()
    {
        try
        {
            //MessageBox.Show("(\"This is an MyMethod coming from C#\")", "haha");
            string path ="你要打开的文件目录";
            System.Diagnostics.Process.Start(path);
        }
        catch(Exception ex)
        {
            MessageBox.Show("请输入正确的文件路径！", "提示");
        }
    }
}

js调用

bound.openFile();

bound在C#中定义，这样就会调用BoundObject类的OpenFile方法
