嘗試調用 webview2.CoreWebView2.Navigate(html) 時出現異常...代碼如下：

        }

        public MainWindow()

            InitializeComponent();

            html = html + "<ul>";
            for (int i = 0; i < 100; i++)
            {
                string id = "id" + i.ToString();
                html = html + "<li><p id=\"" + id

            }
            html = html + "</ul>";

         }

        private void Go_Click(object sender, RoutedEventArgs e)
        {
        }
    }
}

需要將 Navigate() 更改為 NavigateToString()

        private void webview2_CoreWebView2InitializationCompleted(
           object sender, 
           CoreWebView2InitializationCompletedEventArgs e)
        {
            Console.WriteLine(html);
            webview2.CoreWebView2.NavigateToString(html);

        }
