利用序列化和反序列化实现深拷贝

private static T BinDeepCopy<T>(T t)
{
using(var ms = new MemoryStream()) {
var bf = new BinaryFormatter();
bf.Serialize(ms,t);
ms.Position = 0;
return (T)bf.Deserialize(ms);
}
}

private static T DomDeepCopy<T>(T t)
{
using(var ms = new MemoryStream()) {
XmlSerializer xml = new XmlSerializer(typeof(T));
xml.Serialize(ms,t);
ms.Position = 0;
return (T)xml.Deserialize(ms);
}
}

private static T SoapDeepCopy<T>(T t)
{
using(var ms = new MemoryStream()) {
var soap = new SoapFormatter();
soap.Serialize(ms,t);
ms.Position = 0;
return (T)soap.Deserialize(ms);
}
}
