Question

我在进行API调用时返回了以下XML。我需要创建一个数组，其中包含<status>，<description>和<order_status>中每个<payment_status>和<fulfillment_status>的值。任何人都可以分享一些对我有帮助的知识吗？

<orderwave>
  <call_result>
    <order>
      <order_number>17377</order_number>
      <orderwave_order_number>RWD-336475921</orderwave_order_number>
      <order_status>
        <status>active</status>
        <description>This order is free to be charged and shipped.  It is open in the orderwave workflow.</description>
      </order_status>
      <payment_status>
        <status>declined</status>
        <description>This order has been declined by the payment network.</description>
      </payment_status>
      <fulfillment_status>
        <status>not shipped</status>
        <description>This order has not been allocated for shipment.</description>
      </fulfillment_status>
    </order>
  </call_result>
  <warning_count>0</warning_count>
  <warnings/>
  <error_count>0</error_count>
  <errors/>
</orderwave>

Answer 1

LinqToXML是我想要的。

我暂时没有这样做，所以我的语法可能不完美。

这样的事情：

var xmlSource = contacts.Load(@"../../return.xml");

var q = xmlSource.Descendants("order").SelectMany(x => x.Elements("order_status")

Answer 2

要扩展我之前的评论，可以通过List<T> Class和LINQ to XML轻松快捷地完成此操作。

使用类来保存每个订单的数据 - 例如：

public class Order
{

    public int OrderNumber { get; set; }
    public string OrderStatus { get; set; }
    public string OrderDescription { get; set; }
    public string PaymentStatus { get; set; }
    public string PaymentDescription { get; set; }
    public string FulfillmentStatus { get; set; }
    public string FulfillmentDescription { get; set; }
}

接下来，您可以将XML加载到XDocument中，使用LINQ to XML解析它并创建Order对象列表：

// Parse the XML string; you can also load the XML from a file.
XDocument xDoc = XDocument.Parse("<orderwave>....</orderwave>");

// Get a collection of elements under each order node
var orders = (from x in xDoc.Descendants("order")
// Use the data for each order node to create a new instance of the order class
              select new Order
              {
                  OrderNumber = ConvertTo.Int32(x.Element("order_number").Value),
                  OrderStatus = x.Element("order_status").Element("status").Value,
                  OrderDescription = x.Element("order_status").Element("description").Value,
                  PaymentStatus = x.Element("payment_status").Element("status").Value,
                  PaymentDescription = x.Element("payment_status").Element("description").Value,
                  FulfillmentStatus = x.Element("fulfillment_status").Element("status").Value,
                  FulfillmentDescription = x.Element("fulfillment_status").Element("description").Value
              }).ToList();
          // Convert the result to a list of Order objects

如果你不想测试它，这是我的头脑，但如果你想使用Lists而不是数组，它应该指向正确的方向。

从c＃中的xml数据创建数组
