c# 内存拷贝 解决json序列化丢失私有数据(二进制序列化反序列化)

public static class CopyEx

{

public static T DeepCopyByBin( 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);

//反序列化成对象

retval = bf.Deserialize(ms);

ms.Close();

}

return (T)retval;

}

}
