Sì, puoi usare ExecuteReader() per questo..
try
{
MySqlDataReader reader = null;
string selectCmd = "SELECT * FROM TabelaUtilizatori";
MySqlCommand command = new MySqlCommand(selectCmd, _dbConnect.getConnection());
reader = command.ExecuteReader();
while (reader.Read())
{
string ColumnName = (string)reader["ColumnName"];
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
