當使用Message.GetBody <>

Question

時，請求中只有根對象被反序列化我試圖創建一個接受任何輸入（Action =「*」）的wcf服務，然後在確定其類型後反序列化消息。爲了測試反序列化的目的，我目前對測試服務的類型進行了硬編碼。

我從反序列化過程中得不到任何錯誤，但是在反序列化發生後只有外部對象被填充。所有內部字段都是空的。我可以成功處理與原始wcf服務相同的請求。

我反序列化這種方式，其中knownTypes預計類型的類型列表：

DataContractSerializer ser = new DataContractSerializer(new createEligibilityRuleSet().GetType(), knownTypes); 
createEligibilityRuleSet newReq = buf.CreateMessage().GetBody<createEligibilityRuleSet>(ser); 

這裏是類和子類的請求對象。這些類由svcutil使用現有wsdl中的自頂向下方法生成。我試圖用DataContracts替換XmlTypeAttributes，用DataMembers替換XmlElements沒有區別。它是createEligibilityRuleSet對象上的CreateEligibilityRuleSetSvcRequest實例，該對象爲null。我在底部包含了請求中檢索到的請求

來自客戶端的請求出現在消息正文中，如下所示。在運行時從消息中檢索。

Answer 1

你看到的具體問題是DataContract不知道如何處理不合格的元素。但是XmlSerializer會這樣做，並且您的類可以正確歸因於XmlSerializer。

所以，你應該使用XmlSerializer的，而不是DataContractSerializer的反序列化正文內容：

public static T GetBodyWithXmlSerializer<T>(this Message msg) 
{ 
    var ser = new XmlSerializer(typeof(T)); 
    T o; 
    using (var reader = msg.GetReaderAtBodyContents()) 
    { 
     o = (T)ser.Deserialize(reader); 
    } 
    return o; 
}
