Question

我在反序列化从Web服务收到的XML响应时遇到问题。响应如下：

<CreateSubscribersResultCollection xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
    <CreatedSubscriberIds xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
        <a:long>206464306</a:long>
        <a:long>306664316</a:long>
    </CreatedSubscriberIds>
    <FailedCreatedSubscribers xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays" />
</CreateSubscribersResultCollection>

我用来反序列化XML的代码如下所示：

internal T GetQueuedResults<T>(string url)
{
    WebRequest request = GetRequestObject(url, "GET");
    var httpResponse = (HttpWebResponse)request.GetResponse();

    using (var responseStream = httpResponse.GetResponseStream())
    {
        XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
        var response = (T)xmlSerializer.Deserialize(responseStream);

        return response;
    }
}

当我反序列化（传递类型CreateSubscribersResultCollection）时，我得到没有错误，而CreatedSubscriberIds的长度为0。我很确定错误在于我如何设计CreateSubscribersResultCollection类，但我无法弄清楚错误是什么。该课程如下：

[DataContract]
public class CreateSubscribersResultCollection : RequestBase
{
    [XmlArray("CreatedSubscriberIds")]
    [XmlArrayItem(typeof(long))]
    public List<long> CreatedSubscriberIds { get; set; }

    [XmlElement("FailedCreatedSubscribers")]
    public string FailedCreatedSubscribers { get; set; }
}

当我实例化类并将其序列化时，出于调试目的，我得到了这些结果：

<CreateSubscribersResultCollection xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <CreatedSubscriberIds>
        <long>206464306</long>
        <long>306664316</long>
    </CreatedSubscriberIds>
    <FailedCreatedSubscribers />
</CreateSubscribersResultCollection>

我希望那里有人知道我做错了什么。我一直在反对这个问题太久了，谷歌一直没有帮助我。

尝试指定名称空间：

    [DataContract]
public class CreateSubscribersResultCollection : RequestBase
{
    [XmlArray("CreatedSubscriberIds")]
    [XmlArrayItem(typeof(long), Namespace="http://schemas.microsoft.com/2003/10/Serialization/Arrays")]
    public List<long> CreatedSubscriberIds { get; set; }

    [XmlElement("FailedCreatedSubscribers")]
    public string FailedCreatedSubscribers { get; set; }
}

确保GetResponseStream()中包含数据。要测试尝试将其保存到文件而不是进行网络连接。将其保存到数据文件并反序列化。如果它被序列化，那就是大部分战斗。如果序列化正确，则反序列化不应该是问题。

无法将XML反序列化为对象
