反序列化SOAP消息的詳細信息

Question

我正在使用Windows應用商店應用程序。

我有以下的手動創建的故障類：

[XmlRoot(Namespace = "http://schemas.xmlsoap.org/soap/envelope/", ElementName = "Fault")] 
public partial class SoapFault 
{ 
    [XmlElement(Form = XmlSchemaForm.Unqualified, ElementName = "faultcode")] 
    public String FaultCode { get; set; } 

    [XmlElement(Form = XmlSchemaForm.Unqualified, ElementName = "faultstring")] 
    public String FaultDescription { get; set; } 

    [XmlElement(Form = XmlSchemaForm.Unqualified, ElementName = "detail")] 
    public InnerException[] Detail { get; set; } 
} 

    [XmlType(Namespace = "http://my.namespace.com", TypeName = "InnerException")] 
    public partial class InnerException 
    { 
     [XmlElement(Form = XmlSchemaForm.Unqualified, ElementName = "message")] 
     public String Message { get; set; } 
    } 

這是我試圖讀取服務器的回覆：

<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><env:Body><env:Fault><faultcode>env:Server</faultcode><faultstring>internal error</faultstring><detail><ns2:InnerException xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://ns1.my.namespace.com" xmlns:ns2="http://my.namespace.com" xmlns:ns3="http://ns3.my.namespace.com"><message>internal error</message></ns2:InnerException ></detail></env:Fault></env:Body></env:Envelope> 

我想讀它是作爲的方式如下：

using (XmlReader reader = XmlReader.Create(await response.Content.ReadAsStreamAsync())) 
{ 
    string SoapNamespace = "http://schemas.xmlsoap.org/soap/envelope/"; 
    try 
    { 
     var serializer = new XmlSerializer(typeof(SoapFault)); 

     reader.ReadStartElement("Envelope", SoapNamespace); 
     reader.ReadStartElement("Body", SoapNamespace); 

     var fault = serializer.Deserialize(reader) as SoapFault; 

     reader.ReadEndElement(); 
     reader.ReadEndElement(); 
    } 
    catch(Exception ex) 
    { 
     throw new Exception("Exception was thrown:" + ex.Message); 
    } 
} 

我已經嘗試添加名稱空間，更改XmlElement屬性，但我總是結束將SoapFault中的Detail屬性設置爲NULL。當我將類型更改爲對象時，我至少得到一個包含數據的XmlNode集。

我必須改變這段代碼才能獲得在序列化中實例化的正確類。

請注意：我不幸被迫手動創建調用，並且不能使用自動生成的代碼。

深受How to Deserialize XML document的啓發，我認爲這應該可以做到。

我生成的類，如下所示：

1. 保存XML服務器回覆到磁盤（C：\ TEMP \ reply.xml）
2. XSD C：\ TEMP \ reply.xml/O：」 c：\ temp「
3. xsd c：\ temp \ reply.xsd reply_app1.xsd/classes/o：」c：\ temp「
4. 將reply_app1.cs添加到您的項目中。

這導致：

是的，產生它的汽車，但我想這將是創建一個類，你就可以反序列化的最簡單方法。你可以這樣做：

XmlDocument document = new XmlDocument(); 
document.Load(Server.MapPath("~/Data/reply.xml")); 

System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(Envelope)); 
Envelope envelope = (Envelope)serializer.Deserialize(new StringReader(document.OuterXml)); 

其正確拿起Detail財產。在你的情況，你會需要使用XmlReader像你之前不是做我new StringReader(document.OuterXml)，並且在使用塊包起來，等

請記住，一些反序列化對象的屬性名稱不會與你的SoapFault類（例如現在稱爲Envelope）中的內容完全匹配，並且其中一些屬性表示爲數組而非單個對象，但您可以調整Xsd以適應需要。
