使用substitutionGroup反序列化消息的問題

我有以下XML消息，我使用XmlSerializer反序列化。由於某些原因，此消息的反序列化會消除XML消息的數據庫部分。我需要一些幫助來完整地反序列化此消息。使用substitutionGroup反序列化消息的問題

這是一個示例測試XML消息。

<?xml version="1.0" encoding="UTF-8" standalone="no" ?> 
<Radars xmlns="http://mycompany.com/2008/c2s2"> 
    <Radar> 
    <Identification> 
     <Identifier>140:141</Identifier> 
     <IP>10.216.1.79</IP> 
     <Label>Radar 1</Label> 
     <Model>Radar123</Model> 
     <Category>Civil</Category> 
    </Identification> 
    <Database> 
     <Radar456General> 
     <Identifier>203</Identifier> 
     <Version>8</Version> 
     <RadarStartStop>false</RadarStartStop> 
     <AntennaRotationSpeed>false</AntennaRotationSpeed> 
     <RadarAntennaRotation>false</RadarAntennaRotation> 
     <AntennaStaringPosition>0</AntennaStaringPosition> 
     </Radar456General> 
    </Database> 
    </Radar> 
</Radars>

我使用的XmlSerializer反序列化上述消息這樣的：

public static T Deserialize<T>(string message) 
    { 
     object obj = null; 

     try 
     { 
      XmlSerializer xs = new XmlSerializer(typeof(T)); 
      StringReader reader = new StringReader(message); 
      XmlTextReader xmlReader = new XmlTextReader(reader); 

      obj = xs.Deserialize(xmlReader); 

      xmlReader.Close(); 
      reader.Close(); 
     } 
     catch (Exception ex) 
     { 
      Console.WriteLine(ex); 
      throw ex; 
     } 

     return (T)obj; 
    }

Radars radars = Serializer.Deserialize<Radars>(message);

反序列化之後，我得到一個空的數據庫部分（意味着radars.radar [0]。 Database.Length == 0）。

消息的模式在單獨的XSD文件中指定。我使用xsd.exe從它生成C＃類。這是XSD文件的部分內容。

那麼如何反序列化與數據庫部分的消息？

嘗試在代碼中創建相同的對象結構，對其進行序列化，並查看他與數據和序列化日期之間的差異，然後纔會知道最新的錯誤。
