[Serializable]
public class Class1
{
    [XmlElement("description")]
    public string Description { get; set; }
}
class Program
{
    static void Main(string[] args)
    {
        var list = new List<Class1> {new Class1() {Description = "Desc1"},new Class1() {Description = "Desc2"}};
        var serializer = new XmlSerializer(typeof(List<Class1>),new XmlRootAttribute("root"));
        var ms = new MemoryStream();
        serializer.Serialize(ms,list);
        ms.Position = 0;
        var result = new StreamReader(ms).ReadToEnd();
    }
}

执行后我们将在’result’变量中有以下内容：

<?xml version="1.0"?>
<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Class1>
    <description>Desc1</description>
  </Class1>
  <Class1>
    <description>Desc2</description>
  </Class1>
</root>

问题是：如何将xml元素名称从“Class1”更改为“Item1”而不改变类名？
