c# - 从收到的消息中呼叫桌面通知

Question

我正在使用 CefSharp 插件开发 C# 应用程序。从此，JavaScript 函数触发了一个 C# 方法，传递数据以显示为桌面通知。我有一个 XAML 文件和显示通知的方式，但我不知道如何将仅作为字符串提供的数据传递给 DesktopNotifications 类。我是 C# 新手。

收到通知的代码：

namespace test_twenty
{
    public partial class Notes: Form
    {
       // class variables
    }  

    private void InitializeChromium()
    {
        chromiumBrowser.RegisterJsObject("callbackObj", new CallbackObjectForJs());    
    } 

    public class CallbackObjectForJs : Window
    {    
        public void showMessage(string msg, string msg2)
        {
            // Here I am getting the message successfully
        }
    }
}

桌面通知部分：

namespace DesktopToastsSample
{
    public partial class MainWindow : Window
    {
        private const String APP_ID = "Microsoft.Samples.DesktopToastsSample";
        public MainWindow()
        {
            InitializeComponent();
            ShowToastButton.Click += ShowToastButton_Click;
        }    

        // Create and show the toast.
        // See the "Toasts" sample for more detail on what can be done with toasts
        private void ShowToastButton_Click(object sender, RoutedEventArgs e)
        {    
            // Get a toast XML template
            XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastImageAndText04);

            // Fill in the text elements
            XmlNodeList stringElements = toastXml.GetElementsByTagName("text");
            for (int i = 0; i < stringElements.Length; i++)
            {
                stringElements[i].AppendChild(toastXml.CreateTextNode("Line " + i));
            }

            // Specify the absolute path to an image
            String imagePath = "file:///" + Path.GetFullPath("tool_mini.png");
            XmlNodeList imageElements = toastXml.GetElementsByTagName("image");
            imageElements[0].Attributes.GetNamedItem("src").NodeValue = imagePath;

            // Create the toast and attach event listeners
            ToastNotification toast = new ToastNotification(toastXml);
            toast.Activated += ToastActivated;
            toast.Dismissed += ToastDismissed;
            toast.Failed += ToastFailed;

            // Show the toast. Be sure to specify the AppUserModelId on your application's shortcut!
            ToastNotificationManager.CreateToastNotifier(APP_ID).Show(toast);
        }

        private void ToastActivated(ToastNotification sender, object e)
        {
            Dispatcher.Invoke(() =>
            {
                Activate();
                Output.Text = "The user activated the toast.";
            });
        }

        private void ToastDismissed(ToastNotification sender, ToastDismissedEventArgs e)
        {
            String outputText = "";
            switch (e.Reason)
            {
                case ToastDismissalReason.ApplicationHidden:
                    outputText = "The app hid the toast using ToastNotifier.Hide";
                    break;
                case ToastDismissalReason.UserCanceled:
                    outputText = "The user dismissed the toast";
                    break;
                case ToastDismissalReason.TimedOut:
                    outputText = "The toast has timed out";
                    break;
            }

            Dispatcher.Invoke(() =>
            {
                Output.Text = outputText;
            });
        }

        private void ToastFailed(ToastNotification sender, ToastFailedEventArgs e)
        {
            Dispatcher.Invoke(() =>
            {
                Output.Text = "The toast encountered an error.";
            });
        }
    }
}

如何将主题和文本作为 DesktopNotification 输出？谢谢你。
