vs使用mysql数据库连接

using System;
using MySql.Data.MySqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "Server=localhost;Port=3306;Database=mydatabase;Uid=myuser;Pwd=mypassword;";
        
        try
        {
            using (MySqlConnection connection = new MySqlConnection(connectionString))
            {
                connection.Open();
                Console.WriteLine("Connected to MySQL!");
                
                string query = "SELECT * FROM mytable";
                MySqlCommand command = new MySqlCommand(query, connection);
                MySqlDataReader reader = command.ExecuteReader();
                
                while (reader.Read())
                {
                    Console.WriteLine(reader["ColumnName"].ToString());
                }
                
                reader.Close();
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error: " + ex.Message);
        }
    }
}
