試圖反序列化XML在C＃

Question

你好，我是執行XML序列化 和我得到這個錯誤：「有反映現場‘消息’錯誤」

我想這是因爲該元素不是必須在XML ..但不太確定。

attachig我的代碼

XML代碼：

<DataStructure> 
<message type="01"> 
<dataBytes position="0" description="Response description" typeOfByte="enum"> 
    <enum val="00" description="Message Legal" /> 
    <enum val="01" description="Message not Recognized" /> 
    <enum val="02" description="Message Data Invalid" /> 
    <enum val="03" description="Unused" /> 
    <enum val="04" description="Buffer Full" /> 
    <enum val="05" description="Unused" /> 
    <enum val="06" description="Notification Error" /> 
    <enum val="07" description="One-Way Network" /> 
    <enum val="08" description="Message Length Error" />  
    <enum val="09" description="Network Unavailable" /> 
    <enum val="0A" description="Node Busy" /> 
</dataBytes> 

<dataBytes position="1" description="Response data" typeOfByte="enum"> 
    <enum val="00" description="Message Legal" /> 
    <enum val="01" description="Message not Recognized" /> 
    <enum val="02" description="Message Data Invalid" /> 
    <enum val="03" description="Unused" /> 
    <enum val="04" description="Buffer Full" /> 
    <enum val="05" description="Unused" /> 
    <enum val="06" description="Notification Error"/> 
    <enum val="07" description="One-Way Network" /> 
    <enum val="08" description="Message Length Error" /> 
    <enum val="09" description="Network Unavailable" />  
    <enum val="0A" description="Node Busy" /> 
    </dataBytes> 
</message> 


<message type="30">  
<dataBytes position="0" description="Node Short ID" typeOfByte="hex"> </dataBytes> 
<dataBytes position="1" description="Node Short ID" typeOfByte="bits">  
    <bit position ="0-2" bitval="" description="Notification Period’ "></bit> 
    <bit position ="3" bitval="" description ="Listening Mode" ></bit> 
    <bit position ="4-5" typebit="enum" > 
     <Enum val="00" description="NA" ></Enum> 
     <Enum val="01" description="Poor" ></Enum> 
     <Enum val="10" description="Good" ></Enum> 
     <Enum val="11" description="Strong" ></Enum> 
    </bit> 
    <bit poistion ="6-7" description="Reserved"></bit>    
</dataBytes> 
</message> 
</DataStructure> 

C＃代碼：

private string readFFDDataStructureXML() 
    { 
     string OK = ""; //the error is exits 

     //perform serialazation for the XML 
     try 
     { 

      string baseDirectory = @"C:\Users\brosenfeld\Perforce\brosenfeld_TA7BarakRo_4075\System\Integration\Tools\Panalyzer\FFDProtocol\DataStructure.xml"; //get current directory 
      using (FileStream stream = new FileStream(baseDirectory, FileMode.Open)) 
      { 
       XmlSerializer XML = new XmlSerializer(typeof(DataStructurecs)); 
       _XMLFFDData = (DataStructurecs)XML.Deserialize(stream); 
      } 
     } 
     //if there is an error 
     catch (Exception err) 
     { 
      if (err.InnerException == null) 
      { 
       OK = err.Message; 
      } 

      else 
      { 
       OK = err.Message + "\n\n" + err.InnerException;

     return OK;

你必須改變你的數據結構，這是正確的：

[XmlRoot("DataStructure")] 
public class DataStructurecs 
{ 

    [XmlElement("message")] 
    public List<Message> Message { get; set; } 
} 

public class Message 
{ 
    [XmlAttribute("type")] 
    public string Type { get; set; } 

    [XmlElement("dataBytes")] 
    public List<DataBytes> DataBytes { get; set; } 
} 

public class DataBytes 
{ 
    [XmlAttribute("position")] 
    public string Position { get; set; } 

    [XmlAttribute("description")] 
    public string Description { get; set; } 

    [XmlAttribute("typeOfByte")] 
    public string TypeOfByte { get; set; } 

    [XmlElement("bit")] 
    public Bits Bits { get; set; } 

    [XmlElement("enum")] 
    public List<Enum> Enum { get; set; } 
} 

public class Enum 
{ 
    [XmlAttribute("val")] 
    public string Val { get; set; } 

    [XmlAttribute("description")] 
    public string Description { get; set; } 
} 


public class Bits 
{ 
    [XmlAttribute("position")] 
    public string Position { get; set; } 

    [XmlAttribute("bitval")] 
    public string Bitval { get; set; } 


    [XmlAttribute("description")] 
    public string Description { get; set; } 


    [XmlElement("Enum")] 
    public List<Enums> BitsEnum { get; set; } 
} 

public class Enums 
{ 
    [XmlAttribute("val")] 
    public string Val { get; set; } 

    [XmlAttribute("description")] 
    public string Description { get; set; } 

}
