如何使用XmlSerializer序列化point3D？

Question

public class Placement 
{
   public Point3D Location { get; set; }
   public Point3D Axis { get; set; }
   public Point3D Direction { get; set; }
}


public class Attribute1
{
  public string Key { get; set; }
  public Type Type { get; set; }
  public Object Value { get; set; }
}

class Program
{
  static void Main(string[] args)
  {
     Attribute1 a =  new Attribute1();
     a.Key = "test";
     var p = new Placement();
     p.Axis = new Point3D(12.0, 22.09, 0);
     p.Location = new Point3D(12.0, 22.09, 0);
     p.Direction = new Point3D(12.0, 22.09, 0);

     a.Value = p;
     var serializer = new XmlSerializer(typeof(Attribute1));
     var path = "E:\\details.xml";
     using (TextWriter writer = new StreamWriter(path))
     {
        serializer.Serialize(writer, a);
     }

     Console.Read();
   }    
}

我正在尝试使用XmlSerializer序列化Point3D 。 我正在使用XmlSerializer序列化包含Attribute1的类的其他属性，但是序列化时出现错误。 请让我知道如何实现这一目标或向我指出相关资源。 谢谢！

您已经告诉您要序列化Attribute1，而不要序列化Placement。 只需更改这一行：

var serializer = new XmlSerializer(typeof(Attribute1), new Type[] { typeof(Placement) });
