1：利用反射實作
public
static
T DeepCopy<T>(T obj)
{
//如果是字元串或值類型則直接傳回
if
(obj
is
string
|| obj.GetType().IsValueType)
return
obj;
object
retval = Activator.CreateInstance(obj.GetType());
FieldInfo[] fields = obj.GetType().GetFields(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Static);
foreach
(FieldInfo field
in
fields)
{
try
{ field.SetValue(retval, DeepCopy(field.GetValue(obj))); }
catch
{ }
}
return
(T)retval;
}
2：利用xml序列化和反序列化實作
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;
}
利用二進制序列化和反序列化實作
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;
}
