如何在调用window.open时在WPF / WebView2应用程序中创建自定义窗口？

<Window x:Class="YourApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:wv2="clr-namespace:Microsoft.Web.WebView2.Wpf;assembly=Microsoft.Web.WebView2.Wpf"
        Title="Your App" Height="450" Width="800">
    <Grid>
        <wv2:WebView2 x:Name="webView" />
    </Grid>
</Window>

using Microsoft.Web.WebView2.Core;
using Microsoft.Web.WebView2.Wpf;

namespace YourApp
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            
            webView.NavigationCompleted += WebView_NavigationCompleted;
        }
        
        private async void WebView_NavigationCompleted(object sender, CoreWebView2NavigationCompletedEventArgs e)
        {
            await webView.EnsureCoreWebView2Async();

            webView.CoreWebView2.NewWindowRequested += CoreWebView2_NewWindowRequested;
        }

        private void CoreWebView2_NewWindowRequested(object sender, CoreWebView2NewWindowRequestedEventArgs e)
        {
            // 在这里自定义新窗口的行为，例如创建一个新的WebView2控件来显示新窗口的内容
            WebView2 newWebView = new WebView2();
            newWebView.Source = e.Uri;
            
            // 将新窗口添加到你的界面中，以便用户能够看到
            // ...

            // 取消默认行为，以阻止WebView2控件打开新窗口
            e.Handled = true;
        }
    }
}
