Answer 1

Charge the libraries

using MySql.Data.MySqlClient;

This is the connection:

public static MySqlConnection obtenerconexion()
{
    string server = "Server";
    string database = "Name_Database";
    string Uid = "User";
    string pwd = "Password";
    MySqlConnection conect = new MySqlConnection("server = " + server + ";" + "database =" + database + ";" + "Uid =" + Uid + ";" + "pwd=" + pwd + ";");

    try
    {
        conect.Open();
        return conect;
    }
    catch (Exception)
    {
        MessageBox.Show("Error. Ask the administrator", "An error has occurred while trying to connect to the system", MessageBoxButtons.OK, MessageBoxIcon.Error);
        return conect;
    }
}
