XML typeof XmlSerializer error
Author
XmlSerializer serializer = new XmlSerializer(typeof(SaveStageData));//<==problem is here(line113)
When I save data, the program will break at the line and appears the error message as below:
http://cid-fbeb6373d9321a7f.skydrive.live.com/self.aspx/Questions/XNAqq/xmlError2.JPG
Could somebody tell me how to solve this problem?
The structure of SaveStageData is wrong?

If you'd looked at the exception details you'd have seen the problem:
Quote:{"WindowsGame1.ObjectBase cannot be serialized because it does not have a parameterless constructor."}

Thanks!! I had solved this problem.
I do not see the exception details. Does it output to the output window?
I use XNA 3.0.
But I have another problem, If I modify the line 130 to be
saveStageData.objeclist.Add(new RoleDraw(,_nModelID, _point2D, _translate, _rotate, _scale));
128 public void AddModel(int _nModelID, Point _point2D, Vector3 _translate, Vector3 _rotate, Vector3 _scale)
129 {
130 saveStageData.objectlist.Add(new ObjectBase(ENUM_OBJECT_TYPE.Role,_nModelID, _point2D, _translate, _rotate, _scale));
131 }
The new error message will appear again.(at the line of serializer.Serialize(stream, saveStageData);).
The new error message is http://cid-fbeb6373d9321a7f.skydrive.live.com/self.aspx/Questions/XNAqq/XmlError3.JPG

I had add a default constructor to RoleDraw and even add [Serializable] to RoleDraw. It does not work.

I had solved the new problem by seeing the inner exception message in Local Window.
The answer is using [XmlInclude(typeof(RoleDraw)) to replace [Serializable]
//[Serializable]
[XmlInclude(typeof(EnemyDraw))]
public class SaveStageData
{
public SaveStageData()
{
enemylist = new List<ObjectBase>();
}
public List<ObjectBase> enemylist;
}

}
public List<ObjectBase> enemylist;
}
