mysql ipv6 監聽參照 https://www.jb51.net/article/133019.htm 這篇文章弄得。Navicat 也可以通過ipv6的賬戶進行連接C# 程序改怎么寫呢這樣么    static void Main(string[] args)    {        using (MySqlConnection conn = new MySqlConnection("server=::1;uid=ipv6test;pwd=root;database=test1;CharSet=utf8"))         {                            string sql = "select * from host";            using (MySqlCommand comm = new MySqlCommand(sql, conn))             {                 conn.Open();                var reader = comm.ExecuteReader();                if (reader.Read())                 {                    string host = reader["host"] == System.DBNull.Value ? string.Empty : reader["host"].ToString();                     Console.WriteLine(host);                 }                 reader.Close();             }         }         Console.ReadKey();     }
