C# Xml序列化失败，简单类上出现NullReferenceException

我有一个要序列化的简单类：

public class InnerCharacter : Object {

    public double xp;
    public double hp;
}

我使用了不同的方法，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);
    }
}

我还尝试了文件流和其他方法，但它们都会导致相同的异常。下面是我如何尝试在Unity中的一个游戏对象上加载代码：

public void Start()
{
    TestSerialize();
}

它们都会因相同的NullReferenceException而失败：

在我看来，异常在代码中发生得比在这里显示的更深，但是您是否验证了“new XmlSerializer（typeof（InnerCharacter））”实际返回的是有效值？或者“new StreamWriter（@“Xml.Xml”）”正在返回有效值，或者该详细信息具有有效值？从

对象继承时出现问题@dbc能否请您创建一个答案？这helped@Dvole-我可以，但我不知道它到底失败了，或者如何解决它。@dbc我刚刚从对象中删除了继承，它就成功了。在我看来，异常在代码中发生得比您在这里显示的更深，但您是否验证了“新的XmlSerializer（typeof（InnerCharacter））”是否实际返回有效值？或者“new StreamWriter（@“Xml.Xml”）”正在返回有效值，或者该详细信息具有有效值？从
