将 XML 转换为 C# 对象

我需要从这些 xml 数据中获取 OrderID：

<?xml version="1.0" encoding="utf-8"?>
<GetOrdersResponse xmlns="urn:ebay:apis:eBLBaseComponents">
  <Timestamp>2015-12-10T16:12:55.184Z</Timestamp>
  <Ack>Success</Ack>
  <Version>967</Version>
  <Build>e967_core_Bundled_5642307_R1</Build>
  <OrderArray>
    <Order>
      <OrderID>865826</OrderID>
      <OrderStatus>Active</OrderStatus>
   </Order>
  </OrderArray>
</GetOrdersResponse>

我已经尝试过这个但不起作用。

var xDoc = XDocument.Parse(xmlResult);
var orderElements = xDoc.Elements("GetOrdersResponse").Elements("OrderArray").Elements("Order");
foreach (XElement elem in orderElements)
{
    var orderId = Convert.ToInt32(_xmlHelper.GetChildElementValue(elem, "OrderID"));
}

请指教。

对于这样的问题，我总是选择使用 XmlSerializer。 使用这个类：

    using System;
    using System.Xml.Serialization;
    using System.Collections.Generic;
    namespace classes
    {
        [XmlType(Namespace = "urn:ebay:apis:eBLBaseComponents")]
   public class Order
    {
        public int OrderID { get; set; }
        public string OrderStatus { get; set; }
    }

    [XmlType(Namespace = "urn:ebay:apis:eBLBaseComponents")]
    public class OrderArray
    {
        public List<Order> Orders { get; set; }
    }

    [XmlRoot(Namespace = "urn:ebay:apis:eBLBaseComponents")]
    public class GetOrdersResponse
    {
        public string Timestamp { get; set; }
        public string Ack { get; set; }
        public string Version { get; set; }
        public string Build { get; set; }
        public OrderArray OrderArray { get; set; }
    }

    }

然后反序列化为您的对象：

XmlSerializer serializer = new XmlSerializer(typeof(GetOrdersResponse ));
using (TextReader reader = new StringReader(xmlResult))
{
    GetOrdersResponse result = (GetOrdersResponse) serializer.Deserialize(reader);
}

int id=result.OrderArray.Orders.First().OrderID; //this will return ID of first object in Orders list.
