.NET XmlIgnore 默认情况下? [英] .NET XmlIgnore By Default?

问题描述

有没有办法让 XmlSerializer 默认忽略所有成员，除非我另有说明?

Is there a way to have XmlSerializer ignore all members by default, unless I say otherwise?

我有一个基类和几个派生类，有很多成员，但大多数我不想被序列化.序列化只能接受少数几个.

I have a base class and several derived classes with lots of members, but most I do not want to be serialized. Only a select few are acceptable for serialization.

推荐答案

不，您不能这样做.

XmlSerializer 正在使用选择退出"过程 - 它将序列化所有内容(所有公共属性)，除非您使用 [XmlIgnore] 属性明确选择退出.没有办法改变这种行为.

The XmlSerializer is using a "opt-out" process - it will serialize everything (all public properties) unless you explicitly opt-out by using the [XmlIgnore] attribute. There's no way of changing this behavior.

另一方面，.NET 3.5 DataContractSerializer 采用另一种方法 - 选择加入.它不会序列化任何东西，除非你特别告诉它，通过用 [DataMember] 装饰你的成员.

The .NET 3.5 DataContractSerializer on the other hand is taking the other approach - opt-in. It will not serialize anything, unless you specifically tell it to, by decorating your members with [DataMember].

那么也许 DataContract 序列化程序适合您?它还有一些优点(不需要无参数构造函数，也可以序列化内部和私有属性，如果需要，它还可以序列化字段而不是属性)，并且它已针对速度进行了调整.也有一些缺点 - 它不支持 XML 节点中的属性 - 因此您必须根据您的要求进行选择.

So maybe the DataContract serializer would work for you? It was a few more advantages (doesn't require a parameter-less constructor, can serialize internal and private properties, too, and it can also serialize fields instead of properties, if needed), and it's tuned for speed. There's some downsides, too - it doesn't support attributes in XML nodes - so you'll have to pick based on your requirements.
