namespace ToastTest
{
	public static class Toast
	{
		private static readonly ToastNotifier toastNotifier;
		private static ToastNotification toastNotification;

		static Toast()
		{
			toastNotifier = ToastNotificationManager.CreateToastNotifier("test");
		}

		/// <summary>トースト通知を行います</summary>
		/// <param name="text">通知する内容</param>
		public static void Notify(string text)
		{
			var toastXml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText01);
			var toastTextElements = toastXml.GetElementsByTagName("text");
			toastTextElements[0].AppendChild(toastXml.CreateTextNode(text));
			if (toastNotification != null)
			{
				toastNotifier.Hide(toastNotification);
			}

			toastNotification = new ToastNotification(toastXml);
			toastNotification.Failed += (ToastNotification n, ToastFailedEventArgs a) => Debug.WriteLine(a.ErrorCode);
			toastNotifier.Show(toastNotification);
