RestSharp序列化没有正确序列化类名

RestSharp似乎没有注意到" serializea "属性，我已经用它来装饰我的一个类名:

人

[Serializable, SerializeAs(Name = "person")]
public class Person
{
    [SerializeAs(Name = "first-name")]
    public string FirstName { get; set; }
    [SerializeAs(Name = "contact-data")]
    public ContactData ContactData { get; set; }
}

ContactData

public class ContactData
{
    [SerializeAs(Name = "email-addresses")]
    public List<EmailAddress> EmailAddresses { get; set; }
}

EmailAddress

[SerializeAs(Name = "email-address")]
public class EmailAddress
{
    [SerializeAs(Name = "address")]
    public string Address { get; set; }
    [SerializeAs(Name = "location")]
    public string Location { get; set; }
}

我使用以下代码序列化XML:

var request = new RestRequest("people/{id}.xml", Method.PUT);
request.AddParameter("id", person.Id, ParameterType.UrlSegment);
request.XmlSerializer = new XmlSerializer();
request.AddBody(person);

但是，生成的XML是这样的:

<person>
    <first-name>Scott</first-name> 
    <contact-data>
        <email-adresses>
            <EmailAddress>
                <address>my@email.com</address> 
                <location>Work</location> 
             </EmailAddress>
        </email-adresses>
    </contact-data>
</person>

您可以看到，<EmailAddress>元素似乎忽略了SerializeAs属性，并且没有像我期望的那样序列化为"email-address"，而所有其他元素都工作得很好。有人知道为什么会发生这种情况或者如何解决吗?
