У меня есть следующий код для разбора части html-страницы.
Я хотел бы знать, как вывести его в список или текстовое поле.
Всякий раз, когда япопробуйте получить необработанную ошибку ExcelE
private void PhoneApplicationPage_Loaded (отправитель объекта, RoutedEventArgs e) {
var doc = new HtmlDocument();
doc.LoadHtml("http://www.sourceURL.com");
var node = doc.DocumentNode.Descendants("div").FirstOrDefault(x => x.Id == "FlightInfo_FlightInfoUpdatePanel");
var value = node.InnerHtml;
this.textBox1.Text = value;
Ошибка исключения:
System.NullReferenceException was unhandled
Message: NullReferenceException
