c# - XMLAttribute 不工作

Question

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; }
}

这里我是如何反序列化它的...

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 反序列化成功，但 processSteps 和 InstrumentTypes 仅获得它们的 Name 属性值。其余属性为空。

谁能告诉我这里出了什么问题。

尝试以下操作:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

            IMAApplications applications = Deserialize(FILENAME);
        }

        static IMAApplications Deserialize(string configFilePath)
        {
            IMAApplications appConfig = null;

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