Scriptableobject assetbundle error in Unity5

I Created a scriptableobject asset："test.asset"
When I loaded it use "AssetDatabase.LoadAssetAtPath();", that is right.
When I build a assetbundle and loaded is use "WWW",it's field is right,but it's property is error.

Code (CSharp):

1. public class MYtest:ScriptableObject
2. {
3.     public string Name;
4.     private int aaa;
5.     public int AAA
6.     {
7.     get { return aaa; }
8.     set { aaa = value; }
9.     }
10. }
11. // function
12. MYtest mt = ScriptableObject.CreateInstance<MYtest>();
13. mt.AAA =199999;
14. mt.Name="Hello";
15. AssetDatabase.CreateAsset(mt,"mytest.asset");
16. AssetDatabase.SaveAssets();
17.  
18. /****************/
19. //Loaded AssetDatabase.LoadAssetAtPath
20. var mt = AssetDatabase.LoadAssetAtPath("mytest.asset", typeof(MYtest));
21. //mt.AAA ->199999
22. //mt.Name ->Hello
23.  
24. /****************/
25. //Loaded WWW
26. string url = @"file:///E:\Test\mytest.unity3d";
27. WWW _www = new WWW(url);
28. yieldreturn _www;
29. MYtest mt = _www.assetBundle.LoadAsset<MYtest>("mytest");
30. //mt.AAA ->0 ERROR!!!
31. //mt.Name ->Hello Right!

You need to mark

Code (csharp):

1.  
2. private int aaa;
3.  

With [SerializeField] tag.

Code (csharp):

1.  
2. [SerializeField] private int aaa;
3.  

Non-public properties without [SerialzieField] are not serialized. Public properties also are not serialized. Classes taht are not marked as [System.Serializable] are not serialized. Generic lists are not serialized for many types, etc.

private not serialized
