這樣..

public void Register(){ 
    string email = "youremail"; 

    if (string.IsNullOrWhiteSpace(email) || !Regex.IsMatch(email, @"\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*")) 
    { 
     DialogHelper.ShowToast(string.Empty, "The email is invalid"); 
     return; 
    } 

    //Continue with your register logic... 
} 

DialogService.cs

public class DialogService 
{ 
    public static void ShowToast(string message, string title) 
    { 
     var notificationXml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText02); 
     var toastElement = notificationXml.GetElementsByTagName("text"); 
     toastElement[0].AppendChild(notificationXml.CreateTextNode(title)); 
     toastElement[1].AppendChild(notificationXml.CreateTextNode(message)); 
     var toastNotification = new ToastNotification(notificationXml); 
     ToastNotificationManager.CreateToastNotifier().Show(toastNotification); 
    } 
}
