这是一个我用的年龄所以想我会在某处记载挣扎。 （道歉提出和回答的问题。）

This is one i struggled with for ages so thought I'd document somewhere. (Apologies for asking and answering a question.)

（C＃.NET 2.0） 我当时正在通过序列化XmlSerializer的一类，我添加了一个新的公共财产但它没有被包含在输出XML。

(C# .net 2.0) I had a class that was being serialized by XmlSerializer, I added a new public property however it wasn't being included in the output XML.

这不是在文档中提到的任何地方我能找到的，但公共属性必须有一组，以及一个get被序列化！我想这是因为它假定，如果你要序列化，那么你会希望从同一个文件反序列化，所以只有序列化的同时拥有了一套和获取属性。

It's not mentioned in the docs anywhere I could find, but public properties must have a set as well as a get to be serialized! I guess this is because it assumes that if you're going to serialize then you'll want to deserialize from the same file, so only serializes properties that have both a set and a get.

推荐答案

如前所述，大多数属性必须同时具有getter和setter;主要的例外是清单 - 例如：

As mentioned, most properties must have both a getter and setter; the main exception to this is lists - for example:

private readonly List<Foo> bar = new List<Foo>();
public List<Foo> Bar {get { return bar; } } // works fine

这将正常工作;但是，如果的XmlSerializer 的查找的二传手 - 它要求它必须是公开的;下面就不会工作

which will work fine; however, if XmlSerializer finds a setter - it demands that it is public; the following will not work:

public List<Foo> Bar {get; private set;} // FAIL

其他的原因，可能不序列化：

Other reasons it might not serialize:

这是不公开使用get和set（或只读的场） 它有一个 [默认值] 属性，并与该值 在它有一个返回一个公共布尔ShouldSerializeFoo（）方法假 它有一个公共布尔FooSpecified {获取;集;} 属性或返回场假 在它被标记 [XmlIgnore] 在它被标记 [作废] it isn't public with get and set (or is readonly for a field) it has a [DefaultValue] attribute, and is with that value it has a public bool ShouldSerializeFoo() method that returned false it has a public bool FooSpecified {get;set;} property or field that returned false it is marked [XmlIgnore] it is marked [Obsolete]

所有这些都会导致其无法序列化

Any of these will cause it not to serialize
