如何序列化.NET集合 [英] How to serialize collections in .net

问题描述

我想从我的app.config文件序列化存储/检索对象的集合。 （我使用的是code从杰夫·阿特伍德的博客文章最后的配置节处理..再访）。

I want to serialize a collection of objects for storage/retrieval from my app.config file. (I'm using the code from an example from Jeff Attwood's blog entry The Last Configuration Section Handler.. Revisited).

我想知道的，就是为什么类型的对象集合

What I want to know, is why collections of objects of type

public class MyClass
{
  ...
}

获得序列化到所谓的XML元素

get serialized to an xml element called

<ArrayOfMyClass>...</ArrayOfMyClass>

在这个例子中，我使用MyClass的对象的泛型列表。我也尝试创建一个新的类继承自列表和生成的XML是完全一样的。

In this example I'm using a generic list of MyClass objects. I've also tried creating a new class which inherits from List and the resultant xml is exactly the same.

有没有一种方法来覆盖使用的XML元素名称序列化/反序列化的时候？

Is there a way to override the xml element name used when serializing/deserializing?

推荐答案

当你从名单继承，你可以尝试沿着东西线

When you inherit from List you can try something along the lines of

[Serializable]
[System.Xml.Serialization.XmlRoot("SuperDuperCollection")]
public class SuperDuperCollection : List<MyClass> { ... }

来装饰你的类，使用不同的XMLATTRIBUTES应该让你有过的方式控制XML输出​​序列化时。

to decorate your class, using the different XmlAttributes should let you have control over the way the XML is output when serialized.

只是一个额外的编辑与一些测试code和输出：

Just an additional edit with some Test Code and output:

[Serializable]
public class MyClass
{
public int SomeIdentifier { get; set; }
public string SomeData { get; set; }
}

....

SuperDuperCollection coll = new SuperDuperCollection
{
    new MyClass{ SomeData = "Hello", SomeIdentifier = 1},
    new MyClass{ SomeData = "World", SomeIdentifier = 2}
};

Console.WriteLine(XmlSerializeToString(coll));

输出：

<SuperDuperCollection xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <MyClass>
    <SomeIdentifier>1</SomeIdentifier>
    <SomeData>Hello</SomeData>
  </MyClass>
  <MyClass>
    <SomeIdentifier>2</SomeIdentifier>
    <SomeData>World</SomeData>
  </MyClass>
</SuperDuperCollection>
