我正在研究Unity3D的组件。我有一个名为List<>的基类类型Task，并且我将从基类继承的对象添加到此列表（名为Action的子类）。我已将[XmlInclude(typeof(Action))]属性添加到我的基类中。当我将列表序列化为XML时，只有基类成员被保存到XML文件中。但我还需要一个儿童会员
//Base Class
[XmlInclude(typeof(Action))]
[XmlRoot(ElementName="Task")]
public class Task : BaseNode
{...}
//Child Class
public class Action : Task
{...}
//Program
public List<Task> list = new List<Task>();
list.Add(new Action());
list.Add(new Task());
//Serializer
void Save()
{
using(var fileStream = new FileStream(fileDirectory, FileMode.CreateNew))
{
var serializer = new XmlSerializer(typeof(List<Task>));
serializer.Serialize(fileStream, nodeList);
}
}

这是我的XML文件。在动作类中，我有一些属性，如assetID和includedScript。那些不保存在XML文件中。那些是子类属性而不是继承。
行动类（儿童）
using UnityEngine;
using System.Collections;
using System.IO;
using UnityEditor;
public class Action : Task
{
[SerializeField]
private string scriptName = "";
[SerializeField]
private string includedScript;
[SerializeField]
private string assetID;
public Action()
: base()
{
WindowTitle = "Action";
}
public Action(string title)
: base(title)
{
}
public Action(Rect windowRect)
: base(windowRect)
{
WindowTitle = "Action";
}
public Action(Rect windowRect, string title)
: base(windowRect,title)
{
}
protected virtual void tick()
{
}
public override void windowDraw()
{
GUI.Label(new Rect(1, 15, 70, 15),"Title:");
WindowTitle = GUI.TextField(new Rect(67, 15, 130, 15), WindowTitle);
GUI.Label(new Rect(1, 35, 70, 15), "Class Name:");
scriptName = GUI.TextField(new Rect(67, 35, 130, 15),scriptName);
if (includedScript == null)
{
if (GUI.Button(new Rect(1, 55, 198, 20), "CreateScript"))
{
string codepath = BehaviorTreeEditor.classesDirectory + "/" + scriptName + ".cs";
FileStream fileStream = new FileStream(codepath, FileMode.CreateNew);
string[] code = File.ReadAllLines(Directory.GetCurrentDirectory().ToString() + "/Assets/Behavior Tree/Resources/Action.txt");
for (int i = 0; i < code.Length; ++i)
{
if (code[i].Contains("_"))
{
code[i] = code[i].Replace("_", scriptName);
break;
}
}
fileStream.Close();
File.WriteAllLines(codepath, code);
includedScript = codepath;
assetID = AssetDatabase.AssetPathToGUID(codepath);
Debug.Log(assetID);
}
}
else
{
GUI.Label(new Rect(1, 55, 70, 15), "Script:");
scriptName = GUI.TextField(new Rect(67, 55, 130, 15),includedScript.ToString());
}
}
}
实际上是一个行为树，它有不同的节点（动作，复合，根和......），我必须保存列表＆lt;＆gt;对于加载树可视化编辑器的统一。
