Or you could look at XmlSerializer and adding attributes to classes.

Some samples using XmlSerializer can be found at http://stackoverflow.com/questions/2292480/xmlserializer-list-item-element-name.

As for manually creating the Xml, I would suggest using the classes in the System.Xml.Linq namespace. To do this as an extension method:

using System.Xml.Linq;
using System.Linq;
public static class IEnumerableExtensions
    {
        public static string ToXml< T>(this IEnumerable< T> source, string rootTag = "List", string itemTag = "Item")
        {
            return new XElement(rootTag, source.Select(item => new XElement(itemTag, item))).ToString();
        }
}

Console.WriteLine(MyList.ToXml("Choices", "Channel"));
