如何使用实体框架核心加载相关实体

// 定义实体类
public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public decimal Price { get; set; }
}

// 配置数据上下文
public class MyDbContext : DbContext
{
    public DbSet<Product> Products { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlServer("YourConnectionString");
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Product>().ToTable("Products");
    }
}

// 加载实体
public class Program
{
    public static void Main()
    {
        using (var dbContext = new MyDbContext())
        {
            var products = dbContext.Products.ToList();
            foreach (var product in products)
            {
                Console.WriteLine($"Product: {product.Name}, Price: {product.Price}");
            }
        }
    }
}
