反序列化數組轉換成複雜的對象

Question

我的XML消息的樣子：

<msg> 
    <reply userid="sales" requestid="2" index="1" pagesize="1000" total="1" type="order"> 
     <order id="12db8625cd4-000" owner="sales"> 
      <qty size="1" working="0"/> 
      <price limit="0.0"/> 
     </order>    
     <order id="12db8636344-000" owner="sales"> 
      <qty size="1000" working="0"/> 
      <price limit="0.0"/> 
     </order> 
    </reply> 
</msg> 

我如何定義訂單對象從答覆陣列讀？我的物品看起來像：

[XmlRootAttribute("reply")] 
public class MessageReply 
{ 
    [XmlAttribute("userid")] 
    public string UserId { get; set; } 

    [XmlAttribute("requestid")] 
    public string RequestId { get; set; } 

    [XmlAttribute("type")] 
    public string Type { get; set; } 

    [XmlArrayItem(typeof(Order))] 
    public List<Order> Orders { get; set; } 
} 

[XmlRootAttribute("order")] 
public class Order 
{ 
    [XmlAttribute("id")] 
    public string Id { get; set; } 
    [XmlAttribute("owner")] 
    public string Owner { get; set;} 
    [XmlAttribute("assignee")] 
    public string Assignee { get; set; } 
    [XmlAttribute("instrumentid")] 
    public string InstrumentId { get; set; } 
    [XmlAttribute("side")] 
    public string Side { get; set;} 
    [XmlAttribute("type")] 
    public string Type { get; set; } 
} 

在我的情況下，訂單應該在一個單獨的元素標籤訂單。我想從回覆元素中讀取它們。你有什麼想法在我的對象XML屬性中改變什麼？

變化：

[XmlArrayItem(typeof(Order))] 
public List<Order> Orders { get; set; } 

到：

[XmlElement("order")] 
public List<Order> Orders { get; set; } 

好... 嚴格說我傾向於（我不喜歡設定名單）使用方法：

private List<Order> orders; 
[XmlElement("order")] 
public List<Order> Orders {get{ return orders ?? (orders = new List<Order>());}} 

您還需要不同的根對象：

[XmlRoot("msg")] 
public class Message 
{ 
    [XmlElement("reply")] 
    public MessageReply Reply { get; set; } 
} 

然後這個工程：

var ser = new XmlSerializer(typeof(Message)); 
MessageReply reply; 
using(var reader = new StringReader(xml)) 
{ 
    reply = ((Message)ser.Deserialize(reader)).Reply; 
}
