在c#中序列化嵌套类？

Question

我要做的是序列化嵌套类.我的代码首先:

[Serializable]
public class SampleClass
{
    [Serializable]
    public class Person
    {
        [XmlElement("Name")]
        public string Name { get; set; }
        [XmlElement("Age")]
        public ushort Age { get; set; }
    }
    [Serializable]
    public class Adress 
    {
        [XmlElement("Street")]
        public string Street { get; set; }
        [XmlElement("House number")]
        public int Number { get; set; }
    }
    public SampleClass()
    { 

    }
    public SampleClass(string _name, byte _age, string _street, int _number)
    {
        Person p = new Person();
        p.Name = _name;
        p.Age = _age;
        Adress a = new Adress();
        a.Street = _street;
        a.Number = _number;
    }
}

我想得到像这样的xml

<?xml version="1.0"?>
<SampleClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" >
<Person>
    <Name></Name>
    <Age></Age>
</Person>
<Adress>
    <Street></Street>
    <HouseNumber></HouseNumber>
</Adress>
</SampleClass>

当我序列化这个SimleClass时:

using (Stream str = new FileStream(@"C:/test.xml", FileMode.Create))
            {
                XmlSerializer serial = new XmlSerializer(typeof(SampleClass));
                SampleClass sClass = new SampleClass("John",15,"Street",34);
                serial.Serialize(str, sClass);
                label1.ForeColor = Color.Black;
                label1.Text = "Ok";
            }

它给我test.xml文件,但该文件内部是:

<?xml version="1.0"?>
 <SampleClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" />

我究竟做错了什么？

谢谢你提前:)

你真正想要序列化的是:

    Person p = new Person();
    p.Name = _name;
    p.Age = _age;
    Adress a = new Adress();

但这些变量是本地的.创建每个属性并使用serializable属性装饰它们.现在它会起作用.

public SampleClass(string _name, byte _age, string _street, int _number)
{
    this.Person = new Person();
    Person p = this.Person;
    p.Name = _name;
    p.Age = _age;
    this.Adress = new Adress();
    Adress a = this.Adress;
    a.Street = _street;
    a.Number = _number;
}

[Serializable]
public Person Person { get; set; }
[Serializable]
public Adress Adress { get; set; }
