【中文标题】XMLAttribute 不工作【英文标题】：XMLAttribute is not working 【发布时间】：2017-05-10 19:51:28 【问题描述】：

我正在将我的 xml 反序列化为 C# 类。

<?xml version="1.0" encoding="UTF-8"?>
<Applications>
    <Application Name = "name1" MakerCheckerType="Operational" SanctionCheckNeeded="N" PreExistCheckNeeded="N" >
    <InstrumentTypes>
        <InstrumentType  Version="1.0" PrimaryKeyExcel="Security Name" Name="Equity">
        </InstrumentType>
        <InstrumentType Name="Bond" Version="1.0" PrimaryKeyExcel="Security Name">
        </InstrumentType>
    </InstrumentTypes>
    <ProcessSteps>
        <ProcessStep VBAFunction="xyz" ExcelName="xyz" Name="Upload" />
        <ProcessStep Name ="Approve_Reject" VBAFunction="xyz" ExcelName="xyz"/>
    </ProcessSteps>
    </Application>
    <Application Name = "name2" MakerCheckerType="Real" SanctionCheckNeeded="Y" PreExistCheckNeeded="Y">
    <InstrumentTypes>
        <InstrumentType  Version="1.0" PrimaryKeyExcel="Security Name" Name="Equity">
        </InstrumentType>
        <InstrumentType Name="Bond" Version="1.0" PrimaryKeyExcel="Security Name">
        </InstrumentType>
    </InstrumentTypes>
    <ProcessSteps>
        <ProcessStep VBAFunction="xyz" ExcelName="xyz" Name="Upload" />
        <ProcessStep Name ="Approve_Reject" VBAFunction="xyz" ExcelName="xyz"/>
    </ProcessSteps>
    </Application>
</Applications>

类是：

[XmlType("ProcessStep")]
public class IMAProcessStep

    private string name;
    private string vbaFunction;
    private string excelName;

    [XmlAttribute("Name")]
    public string Name
    
        get  return name; 
        set  name = value; 
    

    [XmlAttribute("VBAFunction")]
    public string VBAFunction
    
        get  return vbaFunction; 
        set  vbaFunction = value; 
    

    [XmlAttribute("ExcelName")]
    public string ExcelName
    
        get  return excelName; 
        set  excelName = value; 
    


[XmlType("InstrumentType")]
public class IMAInstrumentType

    [XmlAttribute("Name")]
    public string Name
    
        get;
        set;
    

    [XmlAttribute("Version")]
    public string Version
    
        get;
        set;
    

    [XmlAttribute("PrimaryKeyExcel")]
    public string PrimaryKeyExcel
    
        get;
        set;
    


[XmlType("Application")]
public class IMAApplication

    [XmlAttribute("Name")]
    public string Name  get; set; 

    [XmlAttribute("MakerCheckerType")]
    public string MakerCheckerType  get; set; 

    public bool IsMakerCheckerType
    
        get
        
            if (MakerCheckerType == "Real")
                return true;
            return false;
        
        set
        
            if (value)
                MakerCheckerType = "Real";
            else
                MakerCheckerType = "Operational";
        
    

    [XmlAttribute("SanctionCheckNeeded")]
    public string SanctionCheckNeeded  get; set; 

    [XmlAttribute("PreExistCheckNeeded")]
    public string PreExistCheckNeeded  get; set; 

    public bool IsSanctionCheckNeeded
    
        get
        
            return SanctionCheckNeeded == "Y";
        
        set
        
            SanctionCheckNeeded = value ? "Y" : "N";
        
    

    public bool IsPreExistCheckNeeded
    
        get
        
            if (PreExistCheckNeeded == "Y")
                return true;
            return false;
        
        set
        
            if (value)
                PreExistCheckNeeded = "Y";
            else
                PreExistCheckNeeded = "N";
        
    

    [XmlArray("ProcessSteps")]
    [XmlArrayItem(ElementName = "ProcessStep")]
    public List<IMAInstrumentType> SupportedInstrumentTypes  get; set; 

    [XmlArray("InstrumentTypes")]
    [XmlArrayItem(ElementName = "InstrumentType")]
    public List<IMAProcessStep> ProcessSteps  get; set;

这是我如何反序列化它...

List<IMAApplication> appConfig = null;

var path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, configFilePath);

var xRoot = new XmlRootAttribute();
xRoot.ElementName = "Applications";
xRoot.IsNullable = true;
var serializer = new XmlSerializer(typeof(List<IMAApplication>), xRoot);


using (var stream = File.OpenRead(path))
    appConfig = (List<IMAApplication>)serializer.Deserialize(stream);


return appConfig;

IMAApplication 成功反序列化，但 processSteps 和 InstrumentTypes 仅获取它们的 Name 属性值。其余属性为空。

谁能告诉我这里出了什么问题。

【讨论】：

试过这段代码，结果和我的一样……在 ProcessStep 中只有 Name 属性正在填充，而不是其他属性 您切换了 ProcessSteps 和 InstrumentTypes 的最后 6 行代码。 当我注意到 Equity 是在 Process 而不是 Instruments 时，我发现了这个问题。 感谢您的帮助...我在这个问题上卡住了两个多小时
