用序列化/反序列化实现对象的（深）拷贝

废话不多，直接上代码。

using System.IO;

using System.Text;

using System.Xml;

using System.Xml.Serialization;



namespace Test

{

    public static class MyExtension

    {

        public static T MyClone<T>(this T self)

        {

            var xmlSerializer = new XmlSerializer(typeof(T));

            var memoryStream = new MemoryStream();

            var xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);         

            xmlSerializer.Serialize(xmlTextWriter, self);

            memoryStream.Position = 0;

            var xmlTextReader = new XmlTextReader(memoryStream);

            var newInstance = (T) xmlSerializer.Deserialize(xmlTextReader);

            return newInstance;

        }        

    }

}

到底能拷贝多深，我也不知道。
