我正在尝试解析上面提到的Response。

 XDocument doc = XDocument.Parse(responseXml);
            XNamespace ns = "https://mws.amazonservices.com/Orders/2013-09-01";
            var data = (from attrib in doc.Descendants(ns + "Order")
                       select new FormsPersistence
                       {

                           AmazonOrderID = (string)attrib.Element(ns+"AmazonOrderID").Value ?? string.Empty,
                           //MerchantOrderID = (string)attrib.Element(ns + "MerchantOrderID").Value ?? string.Empty,
                           //PurchaseDate = (string)attrib.Element(ns + "PurchaseDate").Value ?? string.Empty,
                           //OrderStatus = (string)attrib.Element(ns + "OrderStatus").Value ?? string.Empty,
                           //ASIN = (string)attrib.Element(ns + "OrderItem").Element(ns + "ASIN").Value ?? string.Empty,
                           //SKU = (string)attrib.Element(ns + "OrderItem").Element(ns + "SKU").Value ?? string.Empty,
                          // ItemStatus = (string)attrib.Element(ns + "OrderItem").Element(ns + "ItemStatus").Value ?? string.Empty,
                           //ProductName = (string)attrib.Element(ns + "OrderItem").Element(ns + "ProductName").Value ?? string.Empty,
                           //Quantity = (string)attrib.Element(ns + "OrderItem").Element(ns + "Quantity").Value ?? string.Empty,

                           //Amount = (string)attrib.Element(ns + "OrderItem").Element(ns + "ItemPrice") == null ? string.Empty : (string)attrib.Element(ns + "OrderItem").Element(ns + "ItemPrice").Element(ns + "Component").Element(ns + "Amount").Value,

                       }).ToList();

我得到的参考没有设置对象错误.... 我评论过每一件事只是为了测试它。即使是第一个元素它的抛出异常。我尝试了一切。如果有人能指出我正确的方向，我将不胜感激。

FormsPersistence是一个类

class FormsPersistence
{

    public string AmazonOrderID { get; set; }
    public string MerchantOrderID { get; set; }
    public string PurchaseDate { get; set; }
    public string OrderStatus { get; set; }
    public string ASIN { get; set; }
    public string SKU { get; set; }
    public string ItemStatus { get; set; }
    public string ProductName { get; set; }
    public string Quantity { get; set; }
    public string Amount { get; set; }


}

我不是在检查整个房产，但是对于第一个房产，它只是一个不同的情况。请注意，XML节点名称区分大小写，因此AmazonOrderID应该是AmazonOrderId：

var data = (from attrib in doc.Descendants(ns + "Order")
            select new
            {

                AmazonOrderID = (string)attrib.Element(ns + "AmazonOrderId"),
                .....
                .....

            }).ToList();

因此，第一个建议是更仔细地查看您的代码。另一个建议如我的评论中所述，只需将XElement转换为合适的值而不是获取XElement.Value属性。

更新：

好的，我看过整个房产。 XML示例中没有名为MerchantOrderID和OrderItem的元素，因此代码中试图访问这些元素的所有行肯定会触发异常。
