下面是 * 上的一个回答：
public static T DeepClone<T>(T obj)
{
using (var ms = new MemoryStream())
{
var formatter = new BinaryFormatter();
formatter.Serialize(ms, obj);
ms.Position = 0; return (T) formatter.Deserialize(ms);
}
}
Notes:
Your class MUST be marked as [Serializable] in order for this to work.
Your source file must include the following code:
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;
仅供参考。
I've seen a few different approaches to this, but I use a generic utility method as such:
