我正在学习 WCF，所以如果我的术语在这里和那里不正确，我深表歉意。

我正在尝试反序列化使用 WCF 发送并由 Fiddler 捕获的肥皂消息，但我不断收到此错误消息：“根级别的数据无效。第 1 行，位置 1。”

使用以下代码设置 WCF 服务：

// Set up WcfProxy DataPortal service url
Csla.DataPortalClient.WcfProxy.DefaultUrl = appRootUrl + "WcfSilverlightPortal.svc";

// Set up WcfProxy Binding
System.ServiceModel.BasicHttpBinding largeBinding = new System.ServiceModel.BasicHttpBinding();
largeBinding.MaxReceivedMessageSize = 20000000;
largeBinding.MaxBufferSize = 20000000;
largeBinding.OpenTimeout = new TimeSpan(0, 10, 0);
largeBinding.ReceiveTimeout = new TimeSpan(0, 10, 0);
largeBinding.CloseTimeout = new TimeSpan(0, 10, 0);
largeBinding.SendTimeout = new TimeSpan(0, 10, 0);
largeBinding.Name = "BasicHttpBinding_IWcfPortal";
Csla.DataPortalClient.WcfProxy.DefaultBinding = largeBinding;

Fiddler中捕获的soap消息如下：

我正在尝试将其反序列化为 Csla.Server.Hosts.Silverlight.CriteriaRequest 类型的对象

这个类的代码如下所示：

  /// </summary>
  [DataContract]
  public class CriteriaRequest
  {

    /// business object type to create.

    public string TypeName { get; set; }

    /// </summary>
    /// <value>The client UI culture.</value>
    [DataMember]
    public string ClientUICulture { get; set; }
  }
}

我尝试从soap消息中获取三个xml元素'Body'、'Fetch'和'request'中的每一个，并将它们存储为一个名为'element'的XElement变量并运行以下代码：

DataContractSerializer dcs = new DataContractSerializer(typeof(CriteriaRequest));
MemoryStream ms = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(element.Value));
ms.Seek(0, SeekOrigin.Begin);
XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(ms, Encoding.UTF8, new XmlDictionaryReaderQuotas(), null);
CriteriaRequest fr = (CriteriaRequest)dcs.ReadObject(reader);

在每种情况下，它都未能反序列化对象，我没有想法。

我想我已经提供了所有相关的信息，但如果还有什么可以帮助的，请告诉我，我会提供的。

谢谢。

您不能使用更简单的序列化程序来直接序列化 CSLA .NET 对象图。XmlSerializer、JsonSerializer 等序列化程序和各种 DataContractSerializer 变体不够复杂，无法完全克隆和对象图，因此 CSLA 不支持它们。

仅支持 BinaryFormatter、NetDataContractSerializer 和 MobileFormatter。

您可能会尝试将业务对象直接公开为服务接口。这是一个糟糕的架构选择，我永远不会选择支持或鼓励任何人这样做。您可能会发现XML Services FAQ页面很有用。
