Question

我正在尝试序列化包含非系统类型的列表。

下面是我的序列化代码，它在顶层工作正常。并返回一个有效的XmlDocument，但似乎不包含内部列表中的任何内容。

我环顾网 - 并且在SO附近 - 但似乎找不到任何东西！

任何帮助都非常感激。

代码：

public static XmlDocument SerializeToXML<T>(List<T> list, string rootElement)
{
    XmlAttributeOverrides overrides = new XmlAttributeOverrides();
    XmlAttributes attr = new XmlAttributes();
    attr.XmlRoot = new XmlRootAttribute(rootElement);
    overrides.Add(typeof(List<T>), attr);

    XmlDocument xmlDoc = new XmlDocument();
    XPathNavigator nav = xmlDoc.CreateNavigator();
    using (XmlWriter writer = nav.AppendChild())
    {
        XmlSerializer ser = new XmlSerializer(typeof(List<T>), overrides);

        ser.Serialize(writer, list);
    }
    return xmlDoc;
}

用于测试的代码：

[TestFixture]
public class BaseTesting
{
    [Test]
    public void test()
    {
        List<ListTestClass> list = new List<ListTestClass>();

        for (int i = 0; i < 20; i++)
        {
            list.Add(new ListTestClass() { intProp = 1, stringProp = "string1", dtProp = DateTime.Now });
        }

        XmlDocument doc = Beyond.Base.Util.XMLUtils.SerializeToXML<ListTestClass>(list, "root");
    }
}

public class ListTestClass
{
    public int intProp { get; set; }

    public string stringProp { get; set; }

    public DateTime dtProp { get; set; }

    [XmlElement("Inner",typeof(InnerListTestClass))]
    public InnerListTestClass inner { get { return new InnerListTestClass() { intProp = 1, stringProp = "string1", dtProp = DateTime.Now }; } }
}

public class InnerListTestClass
{
    public int intProp { get; set; }

    public string stringProp { get; set; }

    public DateTime dtProp { get; set; }
}

XML输出：

Answer 1

inner属性必须具有setter才能进行序列化。

如果您将其更改为

public InnerListTestClass inner { get; set; }

它将按照您的预期进行序列化。

<ListTestClass>
<intProp>1</intProp>
<stringProp>string1</stringProp>
<dtProp>2011-06-07T01:57:07.1200742-07:00</dtProp>
<Inner>
    <intProp>1</intProp>
    <stringProp>string1</stringProp>
    <dtProp>2011-06-07T01:57:07.1210743-07:00</dtProp>
</Inner>
</ListTestClass>

序列化List <t>包含List <t> </t> </t>
