Есть окно , на котором есть Комбо-бокс и лист-бокс.
Нужно считаь данные их этого XML файла, например, в комбо бокс.
Например, то, что стоит в 1.
<MenuPosition>Pasta....</MenuPosition>
нужно добавить в комбобокс. Все это должно сделаться при загузке окна - 1.
<ComboBox IsSynchronizedWithCurrentItem="True" HorizontalAlignment="Left" Name="MenuPos" Loaded="FillMyListBox" Margin="8,95,0,0" VerticalAlignment="Top" Width="260" Height="36"/>
Вот мой код поиска и добавления элементов -

private void FillMyListBox(object sender, EventArgs e)
{
XmlTextReader reader = new XmlTextReader("MenuFood.xml");
XmlNodeType type;
while (reader.Read()) {
type = reader.NodeType;
if (type == XmlNodeType.Element) {
if (reader.Name=="MenuPosition"){
reader.Read();
MenuPos.Items.Add(reader.Value);
}
}
}
reader.Close();
}
Когда я запускаю приложение, то оно зависает.
Подскажите, пожайлуста, в чем проблема.
У меня еще второй вопрос -
кроме элементов, стоящих в <MenuPosition>
нужно считать еще и SubElements.
К примеру, в <MenuPosition> стоит "Pasta". Потом дальше идут разновидности этого элемента , допустим, Pasta yyyy, Pasta xxxxxx, Pasta zzzzzz.....и так далее, стоящие в тегах <Item1>,<Item2>,<Item3>
Подкиньте, пожайлуста, идею, как это релизовать? Если в комбо бокс стоит "Pasta", то в лист боксе должно стоять Pasta yyyyyyy, Pasta xxxxxx, Pasta zzzzzzzzz.
Нужен ли второй ридер?
спасибо за ответы |
