C# Serialize an object with a list of objects in it
提问by Max Young
In C# if I serialize an object that has a list of objects in it will it also serialize the list?
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？
Example
例子
public class Move {
public string MoveName {get; set;}
public List<Tag> oTags = new List<Tag>;
}
public class Tag {
public string TagName {get; set;}
}
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?
如果我序列化 move 中存储的所有标签也会被序列化吗？另外，如果它不会序列化列表，我将如何让它做到这一点？
<Move>
<MoveName>name</MoveName>
<Tag>Value</Tag>
...
</Move>

Yes, using the XmlSerializerit will serialize a List<T>so long as T(or in your case Tag) is serializable.
是的，只要（或在您的情况下）是可序列化的，使用XmlSerializer它就会序列化。List<T>TTag
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());
This outputs using your current class structure as:
这使用您当前的类结构输出为：
<?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>
I'll see if I can find a way to match your current XML schema, but you can look up how to apply XmlAttributesand play around with it yourself.
我会看看我是否能找到一种方法来匹配您当前的 XML 架构，但是您可以查找如何应用XmlAttributes并自己尝试使用它。
EDIT:
编辑：
If you change your class declaration to use the following XmlAttributes, you will achieve the exact XML schema as in your example:
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：
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;}
}
Which when serialized will produce:
序列化时将产生：
<?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>

By default, no it won't, since the items within the list may not be serializable.
默认情况下，不会，因为列表中的项目可能无法序列化。
If they are, then you may find the following page userful:
如果是，那么您可能会发现以下页面很有用：
回答by Kas
Are you sure that your class Declarations are right in your Question ?
you are just declaring Public Move, It should be Public class Move
你确定你的类声明在你的问题中是正确的吗？你只是声明Public Move，应该是Public class Move
Try this code
试试这个代码
XmlSerializer serializer = new XmlSerializer(typeof(YourClass));
In Your case
在你的情况下
Move m = new Move();
m.oTags.Add(new Tag() { TagName = "X" });
m.oTags.Add(new Tag() { TagName = "XX" });
XmlSerializer x = new XmlSerializer(typeof(Move));
System.IO.Stream s;
var xmlwriter = System.Xml.XmlWriter.Create("C:\MXL.txt");
x.Serialize(xmlwriter, m);
OutPut
输出
<?xml version="1.0" encoding="utf-8"?>
<Move xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<oTags>
<Tag>
<TagName>X</TagName>
</Tag>
<Tag>
<TagName>XX</TagName>
</Tag>
</oTags></Move>
