序列化列表<；T>；包含列表<；T>；

本文关键字：gt lt 列表 包含 序列化 | 更新日期: 2023-09-27 17:58:45

我正在尝试序列化一个包含非系统类型的列表。

下面是我的序列化代码，它在顶级上运行良好。并返回一个有效的XmlDocument，但似乎在内部列表中不包含任何内容。

我看了看网，也看了看SO，但似乎什么都找不到！

非常感谢您的帮助。

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：

序列化列表<；T>；包含列表<；T>；

inner属性必须具有setter才能序列化。

如果您将其更改为

public InnerListTestClass inner { get; set; }

它将被序列化，正如你所期望的那样

<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>
