DataContractSerializer vs XmlSerializer: Pros and Cons of each serializer
提问by Vitali Climenco
My desktop application serializes objects using XmlSerializer. I was suggested to leverage DataContractSerializerinstead.
Under which scenarios should I use DataContractSerializer?
我的桌面应用程序使用XmlSerializer. 有人建议我DataContractSerializer改用杠杆。
我应该在哪些场景下使用DataContractSerializer？
Many thanks
非常感谢

1. The output XML file is stored locally. No other applications deserialize objects from that XML file.
2. My application runs with .NET Framework 3.5 SP1.

He says all there is to say, and in a very convincing way.
他把所有要说的都说了，而且非常有说服力。
In short:
简而言之：
XmlSerializer:
XmlSerializer：
- has been around for a long time
- is "opt-out"; everything public gets serialized, unless you tell it not to ([XmlIgnore])
- 已经存在很长时间了
- 是“选择退出”；所有 public 都被序列化，除非你告诉它不要 ([XmlIgnore])
DataContractSerializer is:
DataContractSerializer 是：
- the new kid in town
- optimized for speed (about 10% faster than XmlSerializer, typically)
- "opt-in" - only stuff you specifically mark as
[DataMember]will be serialized - but anything marked with
[DataMember]will be serialized - whether it'spublicorprivate - doesn't support XML attributes (for speed reasons)
- 镇上的新来的孩子
- 针对速度进行了优化（通常比 XmlSerializer 快 10%）
- “选择加入” - 只有您特别标记的内容
[DataMember]才会被序列化 - 但任何标记
[DataMember]将被序列化-无论是public或private - 不支持 XML 属性（出于速度原因）
