c# - 从 XmlSerializer 生成 Xml 时如何控制 Xml 文档中字符串项数组的 XmlElement 名称

Question

我正在使用 XmlSerializer 类将对象序列化为 xml 文件并通过线路传输。我创建了以下数据结构，其中包含数据并通过线路传输。

 [Serializable]
 public class MailItem
{
    public string UniqueEmailId { get; set; }
    public string SenderEmailId { get; set; }
    public string[] ToRecipientEmailId { get; set; }
}

现在，当我转换为 xml 时，它会发出以下结果 –

<?xml version="1.0" encoding="utf-16"?>
<MailItem xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <UniqueEmailId>SomeUniqueID</UniqueEmailId>
  <SenderEmailId><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="fa899f949e9f88ba9f979b9396d4939e" rel="noreferrer noopener nofollow">[email protected]</a></SenderEmailId>
  <ToRecipientEmailId>
    <string><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="8fdbe0cfeae2eee6e3a1e6eb" rel="noreferrer noopener nofollow">[email protected]</a></string>
    <string><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="da8eb5eb9abfb7bbb3b6f4b3be" rel="noreferrer noopener nofollow">[email protected]</a></string>
    <string><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="81d5eeb3c1e4ece0e8edafe8e5" rel="noreferrer noopener nofollow">[email protected]</a></string>
  </ToRecipientEmailId>  
</MailItem>

预期结果是(观察 ToRecipientEmailId 的子元素)-

<?xml version="1.0" encoding="utf-16"?>
<MailItem xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <UniqueEmailId>SomeUniqueID</UniqueEmailId>
  <SenderEmailId><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="d5a6b0bbb1b0a795b0b8b4bcb9fbbcb1" rel="noreferrer noopener nofollow">[email protected]</a></SenderEmailId>
  <ToRecipientEmailId>
    <EmailId><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="4b1f240b2e262a222765222f" rel="noreferrer noopener nofollow">[email protected]</a></EmailId>
    <EmailId><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="43172c7203262e222a2f6d2a27" rel="noreferrer noopener nofollow">[email protected]</a></EmailId>
    <EmailId><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="d480bbe694b1b9b5bdb8fabdb0" rel="noreferrer noopener nofollow">[email protected]</a></EmailId>
  </ToRecipientEmailId>  
</MailItem>

当我创建另一个类并将 Email 和 EmailId 作为属性时，它给出了以下结果 –

[Serializable]
     public class MailItem
    {
        public string UniqueEmailId { get; set; }
        public string SenderEmailId { get; set; }
        public List<Email> ToRecipientEmailId { get; set; }
    }         

   public class Email
    {
        public string EmailID {get;set;}
    }

<?xml version="1.0" encoding="utf-16"?>
<MailItem xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <UniqueEmailId>SomeUniqueID</UniqueEmailId>
  <SenderEmailId><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a8dbcdc6cccddae8cdc5c9c1c486c1cc" rel="noreferrer noopener nofollow">[email protected]</a></SenderEmailId>
  <ToRecipientEmailId>
    <Email>
      <EmailID><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1c48735c79717d7570327578" rel="noreferrer noopener nofollow">[email protected]</a></EmailID>
    </Email>
    <Email>
      <EmailID><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="194d7628597c7478707537707d" rel="noreferrer noopener nofollow">[email protected]</a></EmailID>
    </Email>
    <Email>
      <EmailID><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="da8eb5e89abfb7bbb3b6f4b3be" rel="noreferrer noopener nofollow">[email protected]</a></EmailID>
    </Email>
  </ToRecipientEmailId> 
</MailItem>

如果有人让我知道如何达到预期的结果，那就太好了。我需要对数据结构进行哪些更改？

Answer 1

您可以使用[XmlArrayItem(elementName)]属性指定用于数组条目的元素名称:

public class MailItem
{
    public string UniqueEmailId { get; set; }
    public string SenderEmailId { get; set; }
    [XmlArrayItem("EmailId")]
    public string[] ToRecipientEmailId { get; set; }
}

请注意，您不需要用于二进制序列化的[Serializable] 属性。
