XML序列化后如何没有列表元素的包装元素[重复]

Question

我有一堂课Payment。类结构如下所示：

public class Payment
{
  public decimal Amount{get;set;}
  public List<Loan> Loans{get;set;}
}
public class Loan
{
  public decimal Debt{get;set;}
  public string Lender{get;set;}
}

当我将它序列化为 XML 时，默认情况下它会产生如下内容：

<Payment>
  <Amount>...</Amount>
  <Loans>
    <Loan>...</Loan>
    <Loan>...</Loan>
  </Loans>
</Payment>

但我想要这样的输出：

<Payment>
  <Amount>...</Amount>
  <Loan>...</Loan>
  <Loan>...</Loan>
</Payment>

我怎样才能达到我想要的输出？

我的 XML 序列化代码是这样的：

System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(Payment));

StringBuilder sb = new StringBuilder();
using (System.IO.TextWriter writer = new System.IO.StringWriter(sb))
{                    
  serializer.Serialize(writer, mainDocument);
  writer.Flush();
}
finalXML = sb.ToString();
// finalXML contains the XML string

只需将您的贷款定义为XmlElement：

public class Payment
{
    public decimal Amount { get; set; }
    [XmlElement("Loan")] 
    public List<Loan> Loans { get; set; }
}
public class Loan
{
    public decimal Debt { get; set; }
    public string Lender { get; set; }
}
