我想要xml序列化包含其他自定义对象的自定义对象。我这样做,但它不会工作。

class A()
{
public B b;
}

class B()
{
public int a;
}

System.Xml.Serialization.XmlSerializer writer = new System.Xml.Serialization.XmlSerializer(typeof(A));  
XmlAttributes xmlAttributes = new XmlAttributes();   
System.IO.StreamWriter file = new System.IO.StreamWriter(   @"d:\SerializationOverview.xml");
writer.Serialize(file, new A());  
file.Close();

结果是:

<A>
</A>

首先,AB都需要标记为public

new A()在序列化b中没有值;它不会序列化空值。给它一个值:

writer.Serialize(file, new A { b = new B { a = 123 } });

另外:尝试优先选择公共领域的属性。

例如:

using System.IO;
using System.Xml.Serialization;
public class A
{
    public B B { get; set; }
}
public class B
{
    public int A {get;set;}
}
static class Program
{
    static void Main()
    {
        var writer = new XmlSerializer(typeof(A));
        using (var file = File.Create(@"SerializationOverview.xml"))
        {
            writer.Serialize(file, new A { B = new B { A = 123 } });
        }
    }
}
