Linq to XML setting XElements from arrayList?

Question

I am trying to set XElements with an ArrayList and having a bit of trouble. I basically want to be able to do a foreach loop, but not sure where I need to insert it.

ArrayList cities = new ArrayList();
foreach (ListItem item in lstCities.Items)
{
    cities.Add(item.Text);
}

new XElement("Cities", cities //not sure what to do here
                            .Select(x=>new XElement("City",x)))  

This does not work, though it worked okay with this, but I want the city names, not array number

new XElement("Countries", lstCountry.GetSelectedIndices()
                              .Select(x => new XElement("Country", x))

Answer 1

Any reason why you're using an ArrayList instead of a List<string> to start with?

If you're forced to use ArrayList then you could do:

cities.Cast<string>()
      .Select(x => new XElement("City", x)

... but you'd be better off using List<string> if possible.

Alternatively:

new XElement("Cities", lstCities.Items
                                .Cast<ListItem>()
                                .Select(x => new XElement("City", x.Text)))
