Question

我有一个现有的XML文档，我试图映射到C＃类。

我还创建了一个单元测试，以确保XML正在被反序列化。

但是，当期望为PageName元素计数为2时，单元测试失败。当我调试时，我看到PageName元素计数为0.同样在调试视图中，各个DeskBroker.Broker元素也有0个计数。

不确定我是否正确设置了XML属性。有人可以检查我的工作，看看我是否使用正确的注释？我确信我错过了一些东西。

谢谢。

这是XML：

<?xml version="1.0" encoding="utf-8"?>
<User>
 <FavoriteQuotePages>
  <Group name="Default">
   <PageName>NG Options</PageName>
   <PageName startdate="today" enddate="today">NG Options</PageName>
  </Group>
  <Group name="CUSTOM PAGES">
   <PageName sourcepagename="NG Options" daterange="TopDay" startdate="today" enddate="today" customfilters="[{&quot;fieldName&quot;:&quot;BidBOEName&quot;, &quot;expr&quot;:&quot;ION&quot;, &quot;cond&quot;:&quot;contains&quot;}]">ION ONLY</PageName>

Answer 1

只需更改

[XmlArray("Group")]
public List<Page> Pages { get; set; }

到

[XmlElement("PageName")]
public List<Page> Pages { get; set; }

享受;）

注意：您的XML使用“today”作为startdate - 这与DateTime无关。

Answer 2

您只需将PagweGroup页面更改为：

[XmlType("Group")]
public class PageGroup
{
    [XmlAttribute("name")]
    public string Name { get; set; }

    [XmlElement("PageName")]
    public List<Page> Pages { get; set; }

    public PageGroup()
    {
        Pages = new List<Page>();
    }
}

而不是XmlArray（“Group”），你必须把XmlElement（“PageName”）

请注意，之后，您的XML在startDate＆amp;中的“today”字符串上有错误。 endDate属性

如何将内部XML反序列化为对象？
