1、项目引用nuget

2、winform窗体中初始化

 var webView = new WebView2();
 webView.Source = new Uri(url);
 webView.Dock = DockStyle.Fill;
 //接收js调用c#函数的消息
 webView.WebMessageReceived += CoreWebView2_WebMessageReceivedAsync;                
 this.panel1.Controls.Add(webView);


//接受js调用c#代码
private async void CoreWebView2_WebMessageReceivedAsync(object sender, CoreWebView2WebMessageReceivedEventArgs e)
        {
            try
            {
                function();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

3、webView2中的js调用c#代码

window.chrome.webview.postMessage(123);
