C#调用js比较容易。JS调用C#代码，现有两种方法。老方法的缺点是只支持单页，如果切换页面，原有创建的变量就失效了。新方法没有这些问题。

Cefsharp js调用c#与c#调用js

CefSharp 与 js 相互调用

https://github.com/cefsharp/CefSharp/issues/2246

  var options = new CefSharp.BindingOptions() {CamelCaseJavascriptNames = false};
            var bindingOptions = options;
            //For async object registration (equivalent to RegisterJsObject)
            this.Browser.JavascriptObjectRepository.Register("boundAsync", new BoundObject(), true, options);
            this.Browser.JavascriptObjectRepository.Register("boundAsync2", new AsyncBoundObject(), true, options);

<script type="text/javascript">
    function aa()
        // <embed user provided code here>
        CefSharp.BindObjectAsync("boundAsync", "bound").then(function (result) {
            boundAsync.hello('CefSharp');
    function bb(){
        CefSharp.BindObjectAsync("boundAsync2").then(function(result)
            boundAsync2.hello('CefSharp');
</script>
