Explanation:

In the above program, we imported a namespace MySql.Data.MySqlClient to establish the connection with the MySql database. Then we created a class Program that contains the Main() method.

The Main() method is the entry point for the program. In the Main() method, we created a connection string variable ConnString that contains the database connectivity credentials. After that, we established the connection to the MySql database using MySqlConnection class and then get the column names using ExecuteReader() and GetName() methods of MySqlDataReader class and then print them on the console screen.
