我一直在犯一些很糟糕的错误：d

public static List<tableName> GetUserStatus(IUser user)
    {
        var result = new List<tableName>();

        var database = new Database("dibot");

        var str = string.Format("SELECT * FROM dibott WHERE userid = '{0}'", user.Id);
        var tableName = database.FireCommand(str);

        while (tableName.Read())
        {
            var userId = (string)tableName["userid"];
            var userName = (string)tableName["username"];
            var currentTokens = (int)tableName["tokens"]; // Here

            result.Add(new tableName
            {
                userid = userId,
                username = userName,
                tokens = currentTokens
            });
        }
        database.CloseConnection();

        return result;

    }

在这个命令下

[Command("Status")]
    [Alias("status", "s")]
    public async Task Status([Remainder] IUser user = null)
    {
        var embed = new EmbedBuilder()
        {
            Color = new Color(0, 0, 255)
        };
        if (user == null)
        {
            user = Context.User;
        }

        var result = Database.CheckExistingUser(user); //Here

        if (result.Count() <= 0)
        {
            Database.EnterUser(user);
        }

        var tableName = Database.GetUserStatus(user);

我什么都试过了请帮帮我。我试过很多东西。没有什么能帮助我寻求帮助，因为我的想法和在互联网上没有任何修复我把//看看哪里是错误。我希望我能很快得到帮助！：）
