.net Xml反序列化程序无法反序列化

我想将xml文件反序列化为对象，但无法将上下文属性从下面的xml获取到对象

<Receipt>
    <Data context="LastYear">
      <OtherIncomeReceiptDataEntity  ID="5011">
        <Amount>5000</Amount>
        <DatePaid>41274</DatePaid>
        <TaxDeducted>1000</TaxDeducted>
        <AllowableExpenses>2000</AllowableExpenses>
        <Status>Ok</Status>
      </OtherIncomeReceiptDataEntity>
    </Data>
    <Data context="CurrentYear">
      <OtherIncomeReceiptDataEntity  ID="5012">
        <Amount>5000</Amount>
        <DatePaid>41274</DatePaid>
        <TaxDeducted>1000</TaxDeducted>
        <AllowableExpenses>2000</AllowableExpenses>
        <Status>Ok</Status>
      </OtherIncomeReceiptDataEntity>
    </Data>
</Receipt>

任何建议都将不胜感激

更新（对象结构）

公共类收据
{
公共列表数据{get；set；}
}
公共类数据
{
[XmlAttribute（“上下文”）]
公共int上下文{get；set；}
公共OtherIncomeReceiptDataEntity OtherIncomeReceiptDataEntity{get；set；}
}

您希望将上下文存储在哪里？更新的修订对象我可以将上下文值存储到OtherIncomeReceiptDataEntity对象，但当将对象序列化回XML时，我需要将其添加回数据元素。我不确定这是否重要，但“context”属性是int类型，而属性不是数字（例如去年）我现在已将上下文更改为字符串，但它不起作用。

public class Receipt
{
    public List<OtherIncomeReceiptDataEntity> Data { get; set; }
}

public class OtherIncomeReceiptDataEntity
{
    [XmlAttribute("openspaceID")]
    public int openspaceID { get; set; }

    public double Amount { get; set; }
    public int DatePaid { get; set; }
    public double TaxDeducted { get; set; }
    public double AllowableExpenses { get; set; }
    public DBEStatus Status { get; set; }
}

    Receipt otherIncomes = null;
    string path = "otherIncomes.xml";

    XmlSerializer serializer = new XmlSerializer(typeof(Receipt));
    StreamReader reader = new StreamReader(path);

    otherIncomes = (Receipt)serializer.Deserialize(reader);         
    reader.Close();

public class Receipt
{
    public List<Data> Data { get; set; }
}

public class Data
{
    [XmlAttribute("context")]
    public int context { get; set; }

    public OtherIncomeReceiptDataEntity OtherIncomeReceiptDataEntity { get; set; } 
}
