首先到网上下载MySql.Data.MySqlClient.dll，然后添加引用到项目

using MySql.Data.MySqlClient;
 
          string connectString = @"server=localhost;userid=root;password=xxx;database=sharejs";   /*由于我的数据库在本地就用localhost了,可以替换成IP地址*/
 
            MySqlConnection conn = new MySqlConnection(connectString);
 
            conn.Open ();
 
            MySqlCommand cmd = conn.CreateCommand();
 
            cmd.CommandText = "select * from info";
 
            cmd.CommandType = CommandType.Text;
 
            using (MySqlDataReader reader = cmd.ExecuteReader())
 
            {
 
                while (reader.Read())
 
                  Console.WriteLine(reader[0].ToString());
 
            }
