Those are classes, not functions. You can follow-up with the documentation to see what they do and what is available with each:  http://dev.mysql.com/doc/refman/5.1/en/connector-net-ref-mysqlclient.html

In short, MySqlConnection represents a connection to a MySql database, MySqlCommand is a class that is used to pass queries to the database using a given MySqlConnection, and MySqlDataReader is a class used to read the results of a selection query processed by a given SqlCommand object.
