vs上使用mysql数据库

using System;
using MySql.Data.MySqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "Server=localhost;Database=mydatabase;Uid=myuser;Pwd=mypassword;";
        using (MySqlConnection connection = new MySqlConnection(connectionString))
        {
            try
            {
                connection.Open();
                Console.WriteLine("Connected to MySQL database!");
            }
            catch (Exception ex)
            {
                Console.WriteLine("Error: " + ex.Message);
            }
        }
    }
}

string sql = "SELECT * FROM users WHERE id = @id";
using (MySqlConnection connection = new MySqlConnection(connectionString))
{
    MySqlCommand command = new MySqlCommand(sql, connection);
    command.Parameters.AddWithValue("@id", 1);
    try
    {
        connection.Open();
        using (MySqlDataReader reader = command.ExecuteReader())
        {
            while (reader.Read())
            {
                Console.WriteLine("User ID: " + reader["id"] + ", Name: " + reader["name"]);
            }
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine("Error: " + ex.Message);
    }
}
