1：利用反射實現

? public T DeepCopy<T>(T obj)
??????? {
?????????? object retval= Activator.CreateInstance(typeof(T));
??????????? PropertyInfo[] pis = typeof(T).GetProperties();
??????????? foreach (PropertyInfo pi in pis)
??????????? {
??????????????? try{pi.SetValue(retval, pi.GetValue(obj, null), null);? }
??????????????? catch{? }
??????????? }
??????????? return (T)retval;?
??????? }

2：利用xml序列化和反序列化實現

?? public T DeepCopy<T>(T obj)
??????? {
??????????? object retval;
??????????? using (MemoryStream ms = new MemoryStream())
??????????? {
??????????????? XmlSerializer xml = new XmlSerializer(typeof(T));
??????????????? xml.Serialize(ms, obj);
??????????????? ms.Seek(0, SeekOrigin.Begin);
??????????????? retval = xml.Deserialize(ms);
??????????????? ms.Close();
??????????? }
??????????? return (T)retval;
??????? }

3：利用二進制序列化和反序列化實現

public?static?T?DeepCopy<t>(T?obj)
{
????object?retval;
????using?(MemoryStream?ms?=?new?MemoryStream())
????{
????????BinaryFormatter?bf?=?new?BinaryFormatter();
????????//序列化成流
????????bf.Serialize(ms,?obj);
????????ms.Seek(0,?SeekOrigin.Begin);
????????//反序列化成對象
????????retval?=?bf.Deserialize(ms);
????????ms.Close();
????}
????return?(T)retval;
}

4：利用silverlight DataContractSerializer實現，用于在silverlight 客戶端使用

?? public static T DeepCopy<T>(T obj)
??????? {
??????????? object retval;
??????????? using (MemoryStream ms = new MemoryStream())
??????????? {
??????????????? DataContractSerializer ser = new DataContractSerializer(typeof(T));
??????????????? ser.WriteObject(ms, obj);
??????????????? ms.Seek(0, SeekOrigin.Begin);
??????????????? retval = ser.ReadObject(ms);
??????????????? ms.Close();
??????????? }
??????????? return (T)retval;
}
