Xml 序列化在简单的 class 上因 NullReferenceException 而失败

Question

我有简单的class我要连载:

public class InnerCharacter : Object {

    public double xp;
    public double hp;
}

我厌倦了不同的做法，例如：

public static void TestSerialize()
{
    InnerCharacter c = new InnerCharacter();
    Serialize(c);
}
static public void Serialize(InnerCharacter details)
{
    XmlSerializer serializer = new XmlSerializer(typeof(InnerCharacter));
    using (TextWriter writer = new StreamWriter(@"Xml.xml")) {
        serializer.Serialize(writer, details);
    }
}

我也试过文件流和其他方法，但它们都导致相同的异常。这是我尝试在我的一个游戏对象上加载 Unity 中的代码的方法：

public void Start()
{
    TestSerialize();
}

它们都因相同的 NullReferenceException 而失败：

XmlSerializer 不适用于从 UnityEngine.Object. Source: XML Serialization error 继承的对象。如果可能，请尝试删除继承。
