内联 XML 元素

问：

我有以下型号：

public PersonInfo
{
    [XmlElement("initials")]
    public string Initials { get; set; }

    [XmlElement("prefix")]
    public string Prefix { get; set; }

    [XmlElement("familyName")]
    public string FamilyName { get; set; }
}

public ContactPerson
{
    [XmlElement("department")]
    public string Department { get; set; }

    public PersonInfo PersonInfo { get; set; }
}

public Driver
{
    [XmlElement("vehicleID")]
    public string VehicleId { get; set; }

    public PersonInfo PersonInfo { get; set; }
}

有没有办法在序列化时内联属性，以便我得到PersonInfoXmlSerializer

<contactPerson>
  <department>SillyWalks</department>
  <initials>J</initials>
  <familyName>Time</familyName>
</contactPerson>

而不是

<contactPerson>
  <department>SillyWalks</department>
  <PersonInfo>
    <initials>J</initials>
    <familyName>Time</familyName>
  </PersonInfo>
</contactPerson>

继承不是一种选择，因为我有多个这样的模型需要内联。
