如何用所需的属性名称序列化POCO

这应该很简单，但显然我错过了技巧。我有一个POCO:

public class job
{
    public string title { get; set; }
    public string company { get; set; }
    public string companywebsite { get; set; }
    public string[] locations { get; set; }
}

我正在使用RestSharp将其序列化为XML。我希望得到任何一个：

<job>
    <title>Hello title</title>
    <company>Hello company</company>
    <locations>New York</locations>
    <locations>Los Angeles</locations>
    <locations>Detroit</locations>
</job>

或者理想情况下。。。

<job>
    <title>Hello title</title>
    <company>Hello company</company>
    <locations>
         <location>New York</location>
         <location>Los Angeles</location>
         <location>Detroit</location>
    </locations>
</job>

但我得到的却是：

<job>
    <title>Hello title</title>
    <company>Hello company</company>
    <locations>
         <String />
         <String />
         <String />
    </locations>
</job>

显然，POCO需要有所不同。我能做什么？

public class job
{
    public string title { get; set; }
    public string company { get; set; }
    public string companywebsite { get; set; }
    [XmlArray("locations")]
    [XmlArrayItem("location")]
    public string[] locations { get; set; }
}
