如何制作贝壳吐司？

问题描述

在我的应用程序中，我想通过 ShellToast 通知用户。

In my application I want to notify the user with the ShellToast.

只需运行...

var toast = new ShellToast
{
    Title = "Nom nom nom!",
    Content = "More! More! Keep feeding me!",
};
toast.Show();

...什么都不会发生，据我所知，它需要从<$ c运行$ c> ScheduledTaskAgent 。但是，如何在命令上运行它，并确保它只运行一次？

...makes nothing happen, and as I understand it needs to be run from a ScheduledTaskAgent. But how do I run this on command, and make sure it only run once?

推荐答案

该应用程序是前台应用程序。

You can't use a ShellToast while the app is the foreground app. It's meant to be invoked from a background service while the app isn't the foreground app.

如果要使用类似于ShellToast的UX，请使用 ToastPrompt控件。这是一个显示代码用法的代码段：

If you want to have a UX similar to that of ShellToast use the Coding4fun toolkit ToastPrompt control. Here's a code snippet showing how to use it:

    private void ToastWrapWithImgAndTitleClick(object sender, RoutedEventArgs e)
    {
        var toast = GetToastWithImgAndTitle();
        toast.TextWrapping = TextWrapping.Wrap;

        toast.Show();
    }

    private static ToastPrompt GetToastWithImgAndTitle()
    {
        return new ToastPrompt
        {
            Title = "With Image",
            TextOrientation = System.Windows.Controls.Orientation.Vertical,
            Message = LongText,
            ImageSource = new BitmapImage(new Uri("../../ApplicationIcon.png", UriKind.RelativeOrAbsolute))
        };
    }

运行此代码段显示以下内容：
