如何将对象序列化为xml？

Question

如何将类A和类B的两个对象序列化为xml，以便它可以采用以下格式：

<root>
<objClassA> //Parent Node
  <objClassB> // child node of objClassA
  </objClassB>
</objClassA>
</root>

Answer 1

[Serializable(true)]
public class objClassB
{
}

[Serializable(true)]
public class objClassA
{
    public objClassB instance;
}

然后使用XmlSerializer作为objClassA的实例，它将自动将b的实例作为子项放在其自身内。

Answer 2

using System;
using System.IO;
using System.Xml.Serialization;

void Write(root rootInstance)
{
    XmlSerializer xmlSerializer = new XmlSerializer(typeof(root));
    using (FileStream fileStream = new FileStream("filepath.xml", FileMode.Create))
    {
        xmlSerializer.Serialize(fileStream, rootInstance);
    }
}

    public class root
    {
        public ClassA objClassA { get; set; }
    }

    public class ClassA
    {
        public ClassB objClassB { get; set; }
    }
    public class ClassB { }
