I want to write an ID in carID from another table, the data in it is filled in, everything is fine with it, carId = el.clothes.IdClothes

I thought the error was that the ID was not created in Order, but that was not the case

Внутреннее исключение 1:SqlException: The INSERT statement conflicted with the FOREIGN KEY constraint “FK_OrderDetail_Clothes_clothesIdClothes”. The conflict occurred in database “ShopClothes”, table “dbo.Clothes”, column ‘IdClothes’.

`public void createOrder(Order order){order.orderTime = DateTime.Now;appDbContent.Order.Add(order);appDbContent.SaveChanges();

var items = shopCart.listShopItems;

foreach (var el in items)
{
    var orderDetail = new OrderDetail()
    {
        carId = el.clothes.IdClothes,
        orderId = order.id,
        price = el.clothes.price
    };
    appDbContent.OrderDetail.Add(orderDetail);
}
appDbContent.SaveChanges();
}
