XML反序列化；元素不是预期的“；错误

我知道以前有人问过这个问题，但我检查了其他线程，没有任何帮助。我正在尝试将xml反序列化为对象，但收到了错误：

"<doPublish xmlns='http://usdoj.gov/leisp/lexs/publishdiscover/3.1'> 
   was not expected."

我的XML看起来像：

<lexspd:doPublish xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://usdoj.gov/leisp/lexs/publishdiscover/3.1 ../xsd/lexs/publish-discover/3.1/publish-discover.xsd"
    xmlns:lexspd="http://usdoj.gov/leisp/lexs/publishdiscover/3.1"
    xmlns:lexs="http://usdoj.gov/leisp/lexs/3.1">
    <lexs:PublishMessageContainer>
        <lexs:PublishMessage>
            <lexs:PDMessageMetadata>
            </lexs:PDMessageMetadata>
        </lexs:PublishMessage>
    </lexs:PublishMessageContainer>
</lexspd:doPublish>

我用来反序列化的代码看起来像：

XmlSerializer xs = new XmlSerializer(typeof(PublishMessageType));
Encoding encode = new UTF8Encoding();
PDWebService lexpdServiceProxy = new PDWebService();
lexpdServiceProxy.Url = "http://59.60.72.12/";
String pdMessageXml = File.ReadAllText(fileName);
DoPublishType doPublishType = new DoPublishType();
MemoryStream publishMsgMemStream = new MemoryStream(encode.GetBytes(pdMessageXml));
doPublishType.PublishMessageContainer = new PublishMessageType[1];
doPublishType.PublishMessageContainer[0] =
   (PublishMessageType)xs.Deserialize(publishMsgMemStream);

我试图反序列化的对象看起来也像：（缩写版本）

我已经尝试添加：

[System.Xml.Serialization.XmlRoot("doPublish", Namespace = "http://usdoj.gov/leisp/lexs/publishdiscover/3.1", IsNullable = true)]

在类的顶部，我也在尝试反序列化，但没有成功。我还尝试将XmlSerializer对象更改为：

XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "doPublish";
xRoot.Namespace = "http://usdoj.gov/leisp/lexs/publishdiscover/3.1";
xRoot.IsNullable = true;
XmlSerializer xs = new XmlSerializer(typeof(PublishMessageType), xRoot);

这是可行的，但反序列化对象中的每个类型都将返回null，即使它们都填充在xml文档中。

任何帮助都将是伟大的，谢谢！
