1.3 Button

按 F12 生成点击事件代码，（async 异步）

private async void Button_Click_1(object sender, RoutedEventArgs e)        {            await new Windows.UI.Popups.MessageDialog("Hello World").ShowAsync();        }        private async void Button_Click_2(object sender, RoutedEventArgs e)        {            var dialog = new ContentDialog()            {                Title = "提示",                Content = "你确认要退出该页面吗?",                PrimaryButtonText = "确定",                SecondaryButtonText = "取消",                FullSizeDesired = false,            };            await dialog.ShowAsync();        }        private async void button_Click(object sender, RoutedEventArgs e)        {                MediaElement mediaElement = new MediaElement();                var synth = new Windows.Media.SpeechSynthesis.SpeechSynthesizer();                Windows.Media.SpeechSynthesis.SpeechSynthesisStream stream = await synth.SynthesizeTextToStreamAsync("I Love U");                mediaElement.SetSource(stream, stream.ContentType);                mediaElement.Play();        }        private async void SubmitButton_Click(object sender, RoutedEventArgs e)        {            // Call app specific code to submit form. For example:            // form.Submit();            Windows.UI.Popups.MessageDialog messageDialog =                new Windows.UI.Popups.MessageDialog("Thank you for your submission.");            await messageDialog.ShowAsync();        }
