C# 序列化一个对象，其中包含一个对象列表 [英] C# Serialize an object with a list of objects in it

问题描述

在 C# 中，如果我序列化一个包含对象列表的对象，它是否也会序列化该列表?

In C# if I serialize an object that has a list of objects in it will it also serialize the list?

示例

public class Move {
    public string MoveName {get;  set;}

    public List<Tag> oTags = new List<Tag>;
}

public class Tag {
    public string TagName {get; set;}
}

如果我序列化 move 中存储的所有标签是否也会被序列化?此外，如果它不会序列化列表，我将如何让它做到这一点?

If I serialize move will all the tags stored in move get serialized as well? Also if it will not serialize the list how would I go about making it do that?

<Move>
  <MoveName>name</MoveName>
  <Tag>Value</Tag>
  ...
</Move>

推荐答案

是的，使用 XmlSerializer 只要T，它就会序列化一个List(或在您的情况下为 Tag)是可序列化的.

Yes, using the XmlSerializer it will serialize a List<T> so long as T (or in your case Tag) is serializable.

Move move = new Move { MoveName = "MyName" };
move.oTags.Add(new Tag { TagName = "Value1" } );
move.oTags.Add(new Tag { TagName = "Value2" } );
move.oTags.Add(new Tag { TagName = "Value3" } );

StringBuilder output = new StringBuilder();
var writer = new StringWriter(output);

XmlSerializer serializer = new XmlSerializer(typeof(Move));
serializer.Serialize(writer, move);

Console.WriteLine(output.ToString());

使用您当前的类结构输出:

This outputs using your current class structure as:

<?xml version="1.0" encoding="utf-16"?>
<Move xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <oTags>
    <Tag>
      <TagName>Value1</TagName>
    </Tag>
    <Tag>
      <TagName>Value2</TagName>
    </Tag>
    <Tag>
      <TagName>Value3</TagName>
    </Tag>
  </oTags>
  <MoveName>MyName</MoveName>
</Move>

我会看看是否能找到一种方法来匹配您当前的 XML 架构，但您可以查找如何应用 XmlAttributes 并自行尝试.

I'll see if I can find a way to match your current XML schema, but you can look up how to apply XmlAttributes and play around with it yourself.

如果您将类声明更改为使用以下 XmlAttributes，您将获得与示例中相同的 XML 架构:

If you change your class declaration to use the following XmlAttributes, you will achieve the exact XML schema as in your example:

public class Move 
{
    [XmlElement(Order = 1)]
    public string MoveName {get; set;}

    [XmlElement(Order = 2, ElementName = "Tags")]
    public List<Tag> oTags = new List<Tag>();
}

public class Tag 
{
    [XmlText]
    public string TagName {get; set;}
}

序列化时会产生:

<?xml version="1.0" encoding="utf-16"?>
<Move xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <MoveName>MyName</MoveName>
  <Tags>Value1</Tags>
  <Tags>Value2</Tags>
  <Tags>Value3</Tags>
</Move>
