我需要在我复杂的对象模型进行深度克隆。你觉得是这样做在.net中的最佳方法是什么？ 我想到了序列化/反序列化 没有必要提及的是 MemberwiseClone 不够好。

I need to perform deep cloning on my complex object model. What do you think is the best way to do that in .Net? I thought about serializing / Deserializing no need to mention that MemberwiseClone is not good enough.

推荐答案

如果你控制的对象模型，那么你可以写code做到这一点，但它是一个大量的维护工作。有很多问题，虽然，这意味着，除非你需要的绝对最快的性能，那么序列化往往是最可控的答案。

If you control the object model, then you can write code to do it, but it is a lot of maintenance. There are lots of problems, though, which mean that unless you need absolutely the fastest performance, then serialization is often the most manageable answer.

这是的情况下，的BinaryFormatter 作品可接受之一;通常我不是一个风扇（由于与版本控制等方面的问题） - 但由于序列化的数据是直接食用的，这不是一个问题。

This is one of the cases where BinaryFormatter works acceptably; normally I'm not a fan (due to the issues with versioning etc) - but since the serialized data is for immediate consumption this isn't an issue.

如果你想让它快一点（但没有自己的code），则 protobuf网可能会有帮助，但需要code的变化（以添加必要的元数据等）。它是基于树的（不基于图形的）。

If you want it a bit faster (but without your own code), then protobuf-net may help, but requires code changes (to add the necessary metadata etc). And it is tree-based (not graph-based).

其它串行（的XmlSerializer ，的DataContractSerializer ）也很好，但如果它的只是的克隆，他们可能不会提供太多了的BinaryFormatter （或许除了的XmlSerializer 不需要 [Serializable接口] 。

Other serializers (XmlSerializer, DataContractSerializer) are also fine, but if it is just for clone, they may not offer much over BinaryFormatter (except perhaps that XmlSerializer doesn't need [Serializable].

因此​​，其实，它取决于你的具体类和场景。

So really, it depends on your exact classes and the scenario.
