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);
