EF API POST Insert与FK表如何插入

public class Order
{
    public int OrderId { get; set; }
    public string OrderName { get; set; }
    // Foreign key property
    public int CustomerId { get; set; }
    public Customer Customer { get; set; }
}

public class Customer
{
    public int CustomerId { get; set; }
    public string CustomerName { get; set; }
    public ICollection<Order> Orders { get; set; }
}

var newOrder = new Order
{
    OrderName = "New Order",
    CustomerId = 1 // 设置外键值
};

using (var context = new YourDbContext())
{
    context.Orders.Add(newOrder);
    context.SaveChanges();
}
