Question

我试图将xml反序列化为一个对象，但它没有正确地通过xml。它不会填充对象中的作者。我试图返回一个由包含标题和作者列表的文章组成的对象。作者列表不会填入此代码，这是我的问题。请帮忙，因为我是这个XML操作的新手。

在这里，您可以看到问题。

以下是xml示例。

<?xml version="1.0" encoding="UTF-8"?>
<MedlineCitationSet>
<Article>
    <ArticleTitle>Title 1</ArticleTitle>
    <AuthorList>
        <Author>
            <LastName>Public</LastName>
            <ForeName>J Q</ForeName>
            <Initials>JQ</Initials>
        </Author>
        <Author>
            <LastName>Doe</LastName>
            <ForeName>John</ForeName>
            <Initials>J</Initials>
        </Author>
    </AuthorList>
</Article>
<Article>
    <ArticleTitle>Title 2</ArticleTitle>
    <AuthorList>
        <Author>
            <LastName>Doe</LastName>
            <ForeName>John</ForeName>
            <Initials>J</Initials>
        </Author>
        <Author>
            <LastName>Doe</LastName>
            <ForeName>Jane</ForeName>
            <Initials>J</Initials>
        </Author>
    </AuthorList>
</Article>  
<Article>
    <ArticleTitle>Title 3</ArticleTitle>
    <AuthorList>
        <Author>
            <LastName>Doe</LastName>
            <ForeName>Jane</ForeName>
            <Initials>J</Initials>
        </Author>
        <Author>
            <LastName>Public</LastName>
            <ForeName>J Q</ForeName>
            <Initials>JQ</Initials>
        </Author>
    </AuthorList>
</Article>
<Article>
    <ArticleTitle>Title 4</ArticleTitle>
    <AuthorList>
        <Author>
            <LastName>Smith</LastName>
            <ForeName>John</ForeName>
            <Initials>J</Initials>
        </Author>
        <Author>
            <LastName>Doe</LastName>
            <ForeName>John</ForeName>
            <Initials>J</Initials>
        </Author>
    </AuthorList>
</Article>

这是我的班级层次结构。

[XmlRoot("MedlineCitationSet")]
public class MedlineCitationSet
{
    [XmlElement("Article")]
    public List<Article> Articles { get; set; }
}

[XmlRoot("Article")]
public class Article
{
    [XmlElement("ArticleTitle")]
    public string ArticleTitle { get; set; }

    [XmlElement("AuthorList")]
    public List<Author> AuthorList { get; set; }
}

public class Author
{
    [XmlElement("LastName")]
    public string LastName { get; set; }

    [XmlElement("ForeName")]
    public string ForeName { get; set; }

    [XmlElement("Initials")]
    public string Initials { get; set; }
}

这是我的反序列化代码。

XmlSerializer serializer = new XmlSerializer(typeof(MedlineCitationSet));
using (FileStream fileStream = new FileStream(newPath + @"\XmlToRead\XmlToRead.xml", FileMode.Open))
{
    MedlineCitationSet result = (MedlineCitationSet)serializer.Deserialize(fileStream);
}

Answer 1

这部分：

[XmlElement("AuthorList")]
public List<Author> AuthorList { get; set; }

表示序列化程序将每个<AuthorList>元素视为作者，而不是xml中的额外<Author>级别。

这可以通过这种方式解决：

[XmlArray("AuthorList")]
[XmlArrayItem("Author")]
public List<Author> AuthorList { get; set; }

PS。通过在代码中生成MedlineCitationSet并对其进行序列化，您可以轻松查看序列化程序对当前序列化映射的影响。

Answer 2

你应该使用[XmlType（＆＃34; MedlineCitationSet＆＃34;）] [XmlType（＆＃34; Article＆＃34;）]和[XmlType（＆＃34; Author＆＃34;）]作为你的属性类，我看到至少缺少类Author中的xml定义。

尝试在作者类上查看xmlroot attributs，然后重试。您可以删除xmlserializer可能自动生成的事实的所有属性。
