Question

Heyo，我正在制作一个团结游戏的插件（下面的错误）所以我可能正在为我的主要插件制作这个并阅读排名。我不知道错误是什么，我没有看到任何关于这个的帖子。这是我的错误：

[XmlArrayItem(ElementName = "Rank")]
public List<Rank> Ranks;
public void LoadDefaults()
{
    Ranks = new List<Rank>() {
    new Rank() { RankNumber = 0, GroupID = "Default" ,Messages = new List<Message>() { new Message("yo") , new Message("yo")}}
    };
}
public class Rank
{
    public Rank() { }

    public int RankNumber;
    public string GroupID;
    public List<Message> Messages;
}
public class Message
{
    public Message(string Rankmessage) { Rankmessage = RankMessage; }
    [XmlAttribute("RankMessage")]
    public string RankMessage;
}

错误：

您需要向Message类添加构造函数。它必须是public，它需要接受零参数。

您已经赢得的现有构造函数不会起作用，因为XML序列化过程不知道如何处理带参数的构造函数。您也可以保留现有的构造函数，只需添加一个不带参数的新构造函数。

无效的操作异常，C＃XML错误
