如图，游戏结算时多个客户端同时请求更新数据库中的数据，报了DataReader的错误，但是我这是更新操作，并没有用到MySqlDataReader，不知道该怎么解决

可能是因为在多个客户端同时请求更新数据库时，由于并发操作，导致了数据读取冲突，从而引发了该错误。

public bool UpdatePlayer(string id, PlayerEntity entity)
{
    try
    {
        MySqlCommand cmd = new MySqlCommand("update player " +
        "set killCount=@killCount," +
        "deathCount=@deathCount," +
        "winCount=@winCount," +
        "loseCount=@loseCount " +
        "where id=@id", mConn);

        cmd.Parameters.AddWithValue("killCount", entity.KillCount);
        cmd.Parameters.AddWithValue("deathCount", entity.DeathCount);
        cmd.Parameters.AddWithValue("winCount", entity.WinCount);
        cmd.Parameters.AddWithValue("loseCount", entity.LoseCount);
        cmd.Parameters.AddWithValue("id", id);

        mConn.Open();
        MySqlTransaction transaction = mConn.BeginTransaction();

        try
        {
            cmd.Transaction = transaction;
            cmd.ExecuteNonQuery();
            transaction.Commit();
            return true;
        }
        catch (Exception ex)
        {
            Console.WriteLine("PlayerDAO UpdatePlayer Error:" + ex.ToString());
            transaction.Rollback();
            return false;
        }
    }
    catch (Exception e)
    {
        Console.WriteLine("PlayerDAO UpdatePlayer Error:" + e.ToString());
        return false;
    }
    finally
    {
        mConn.Close();
    }
}你试试
