Answer 4

I pieced this together by copy/paste from an existing project then sanitizing it...so it's not been compiled and tested, but you get the idea. So here's some sample code to get you started:

using MySql.Data.Types;
using MySql.Data.MySqlClient;    

private void Function()
    {
                    //Set up connection, SqlHost/etc are classwide and declared elsewhere:
                    MySql connection = new MySqlConnection("SERVER=" + SqlHost + ";DATABASE=" + DatabaseName + ";UID=" + user + ";PASSWORD=" + password + ";pooling=false");

                    //Setup query:
                    MySqlCommand command = connection.CreateCommand();
                    MySqlDataReader Reader;    
                    command.CommandText = "your query here";

                    //Connect to relation system and execute query:
                    connection.Open();
                    Reader = command.ExecuteReader();
                    while(Reader.Read())
                    {
                        MessageBox.Show("here's a row from the query response: " + Reader[0].ToString());
                    }

                    //Clean up:
                    connection.Close();
                    Reader.Close();
    }
