c#xml序列化分组子节点中的元素

[XmlRoot("person",Namespace = "",IsNullable = false)]
public class Person
{
    [XmlElement("male")]
    public bool Male { get; set; }

    [XmlElement("street")]
    public string Street { get; set; }

    [XmlElement("city")]
    public string City { get; set; }
}

这将创建以下XML：

<person>
 <male>true</male>
 <street>Some street</street>
 <city>City</city>
</person>

但是我想将(例如街道和城市分组)成为子元素,而不是创建一个包含这两个属性的额外子类.

<person>
     <male>true</male>
     <address>
       <street>Some street</street>
       <city>City</city>
     </address>
 </person>
