wcf - DataContractSerializer ReadObject(stream) 返回空值

Question

我无法将一些 XML 反序列化为适当的对象结构。当我调用ReadObject(stream)它DataContractSerializer时，它返回一个空数组。没有错误，不为空，只是一个空数组。

故事

我正在使用第 3 方服务，他们提供了 wsdl。我已将 wsdl 作为服务引用添加到我的项目中。我已成功调用此服务并收到响应，该响应已由 .Net 正确反序列化。所以我知道响应能够被反序列化。

我调用了一次服务以获取一些初始数据。然后，当第 3 方更新该数据时，他们将使用服务返回的相同响应 XML POST 到 MVC URL。当我尝试从 Request.InputStream 反序列化 XML 时，我得到一个空数组。

我已经搜索和搜索，但显然不是在正确的地方，因为我完全空白。

我真的很感激你能提供的任何方向。

以下是正在播放的代码和文件：

我的反序列化代码- 非常简单的东西，不是吗？updatedData是有问题的空数组。

    var dcs = new DataContractSerializer(typeof(IEnumerable<Account1>),
        "ListOfIrstAccountBrandAccountResponseIo",
        "http://www.siebel.com/xml/IRST%20Account%20Brand%20Account%20Response%20IO");

    var updatedData = (IEnumerable<Account1>)dcs.ReadObject(stream);

    return updatedData;

XML - 数据已被清理，但对于本示例，它并不重要。

<ListOfIrstAccountBrandAccountResponseIo xmlns="http://www.siebel.com/xml/IRST%20Account%20Brand%20Account%20Response%20IO">

wsdl - 我从文件中删除了端点 IP 地址。它不是公共服务，但调用该服务不是测试此场景所必需的。

看来我试图使用错误的序列化程序进行反序列化。3rd 方服务的 wsdl 的早期版本与DataContractSerializer. 他们实施的更改显然与我不兼容DataContractSerializer并svcutil.exe切换到 using XmlSerializer，我不知道。

我切换到使用XmlSerializer反序列化，事情终于奏效了。
