Answer 1

您如何在 .NET （特别是 C#）中对 object 进行深层复制？

Answer 2

一种便宜的方法是对其进行序列化，然后使用二进制序列化直接反序列化。

MyObject myobj = new MyObject(); 
// ...

MemoryStream ms = new MemoryStream();
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(ms, myObj);

MemoryStream ms2 = new MemoryStream(ms.ToArray());

var myobj2 = (MyObject)formatter.Deserialize(ms2);

Answer 3

实现IClonable并在Clone方法中自己提供克隆。
