C＃XML反序列化包含属性和字符串列表的对象会产生一个空列表吗？
[英]C# XML Deserialize an Object containing an attribute and a list of string yields an empty list?
问题描述
I am currently attempting to deserialize the following mesage: 
我目前正在尝试反序列化以下消息：
<Message Id="1234">
<Body>This</Body>
<Body>Is</Body>
<Body>Test</Body>
<Body>Text</Body>
</Message>
Using the Following object: 使用以下对象：
public class Message
{
[XmlAttribute("Id")]
public string Id { get; set; }
[XmlArrayItem("Body")]
public List<string> data { get; set; }
public Message()
{
data = new List<string>();
}
}
The object successfully deserializes, but, the Message.data.Count is 0. I have tried adding an [XmlArray(ElementName="Message")] tag to data and still the string is empty. 该对象成功反序列化，但是Message.data.Count为0。我尝试向数据添加[XmlArray(ElementName="Message")]标记，但字符串仍然为空。
Thank you in advance! 先感谢您！

Change [XmlArrayItem("Body")] to [XmlElement("Body")] : 将[XmlArrayItem("Body")]更改为[XmlElement("Body")] ：
public class Message
{
[XmlAttribute("Id")]
public string Id { get; set; }
[XmlElement("Body")]
public List<string> data { get; set; }
public Message()
{
data = new List<string>();
}
}
This tells XmlSerializer that the list is to be formatted as a one-level sequence of elements rather than a two-level nested list. 这告诉XmlSerializer ，该列表将被格式化为元素的一级序列，而不是两级嵌套列表。
With XmlArrayItem , your XML would need to look like this: 使用XmlArrayItem ，您的XML需要看起来像这样：
<Message Id="1234">
<data>
<Body>This</Body>
<Body>Is</Body>
<Body>Test</Body>
<Body>Text</Body>
</data>
</Message>
