Question

我正在使用XmlSerializer编写反序列化器.Deserialize。基本的反序列化器工作，所以我不会用该代码混淆问题。我写了一个类来存储数据。我成功地反序列化了一个节点，如

 <TransactionDate>2013-11-20T18:26:35.363</TransactionDate>

使用

public string TransactionDate { get; set; }

但是我如何取消选择这些节点以提取数据

<Product version="1.1.0" name="Product Name"/>

或

<Warning message="A Warning message here"/>

我正在使用现有服务，因此我无法更改输入xml的格式化方式。

我尝试过使用XmlElement属性

[XmlElement("Product version")]
public string Productversion { get; set; }

或

[XmlElement("Warning message="A Warning message here"/>)]
public List<string> Message  { get; set; } }

第二个有转义字符问题，都返回null。

如何反序列化包含实际标记中的数据的节点＆lt; .....＆gt;？我班上的财产会是什么样子？

更新遵循fcuesta的建议（不需要XmlElement属性，它没有任何区别）我试过

public class Product { public string version { get; set; } public string name { get; set; }  }

成员仍然没有填充并且为空。

杰森的回答奏效了。他的代码和我将[XmlRoot()]应用到我的代码时。但是Xml实际上是嵌套的，并且还有标签，其中数据位于标签中以及标签之间（Answer节点）。这是Xml：

以下是我的课程：

[XmlRoot("PlatformResponse")]
public class IDChckRspn
{
    //public TransactionDetails TransactionDetails { get; set; }
    public Response Response { get; set; }
}

public class Response
{
    public Questions Questions { get; set; }
}

public class Questions
{
    [XmlElement("Question")]
    public List<Question> Question { get; set; }
}

public class Question
{
    [XmlAttribute("text")]
    public string Text { get; set; }
    [XmlAttribute("type")]
    public string Type { get; set; }
    [XmlElement("Answer")]
    public List<Answer> Answer { get; set; }
}

public class Answer
{
    [XmlAttribute("correct")]
    public string Correct { get; set; }
    [XmlText()]
    public string Text { get; set; }
}

这是我的反序列化器：

  XmlSerializer s = new XmlSerializer(typeof(IDChckRspn));
  StreamReader r = new StreamReader(@"c:\temp\response.xml");
  object obj = s.Deserialize(r);
  IDChckRspn _response = (IDChckRspn)obj;

这成功地反序列化了树和在标记中以及标记之间包含数据的Answer标记。 注意：这是通过使用四个不同的属性来装饰各种类和成员来实现的。

    [XmlRoot("PlatformResponse")]  [XmlElement("Question")] [XmlAttribute("text")] [XmlText()]

    {

        XmlSerializer serializer = new XmlSerializer(typeof(ParentNodeName));

        FileStream stream = new FileStream(@"FakeData.xml", FileMode.Open);

        var item = (ParentNodeName)serializer.Deserialize(stream);
    }
}

FakeData.xml的内容如下所示：

<Item>
    <TransactionDate>someDate</TransactionDate>
    <Product version="someVersion" name="someName" />
    <Warning message="someMessage" />
</Item>
