我有一个实现ICollection<T>
的集合类,其中包含一些用于完整性的自定义属性..
在这个简单的示例中,它是一个简单的请求/结果模式,请求本身作为结果类的属性传回。
[Serializable]
public class MyRequest
{
public int SearchID { get; set; }
}
[Serializable]
public class MyResults : ICollection<MyElement>
{
public MyRequest RequestDetails { get; set; }
private ICollection<MyElement> _list = new List<MyElement>();
/* ICollection interface methods removed */
}
[Serializable]
public class MyElement
{
public int ID { get; set; }
}
这是用于实例化然后输出序列化字符串的示例程序。
class Program
{
static void Main(string[] args)
{
MyResults m = new MyResults();
m.RequestDetails = new MyRequest() { SearchID = 1 };
for (int i = 1; i <= 5; i++)
{
m.Add(new MyElement { ID = i });
}
XmlDocument xmlDoc = new XmlDocument();
XmlSerializer xmlSerializer = new XmlSerializer(m.GetType());
using (MemoryStream xmlStream = new MemoryStream())
{
xmlSerializer.Serialize(xmlStream, m);
xmlStream.Position = 0;
xmlDoc.Load(xmlStream);
}
System.Diagnostics.Debug.WriteLine(xmlDoc.OuterXml);
}
}
问题是输出不包括MyRequest
详细信息......
<?xml version="1.0"?>
<ArrayOfMyElement xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<MyElement>
<ID>1</ID>
</MyElement>
<MyElement>
<ID>2</ID>
</MyElement>
<MyElement>
<ID>3</ID>
</MyElement>
<MyElement>
<ID>4</ID>
</MyElement>
<MyElement>
<ID>5</ID>
</MyElement>
</ArrayOfMyElement>

XmlSerializer
在序列化集合时总是忽略额外的属性;据我所知,唯一的方法就是不在ICollection<MyElement>
类上实现MyResults
,而是将集合公开为属性:
public class MyResults
{
public MyRequest RequestDetails { get; set; }
public ICollection<MyElement> Items { get; set; }
}
(XML序列化不需要Serializable
属性)

只需将 ICollection 更改为 Collection ,因为XmlSerialization不支持通用接口:
public class MyResults
{
public MyResults()
{
this.Items= new Collection<MyElement>();
}
public MyRequest RequestDetails { get; set; }
public Collection<MyElement> Items { get; set; }
}
