這是this post排除某個模型項目 - MVC/ASP.Net
一個跟進的問題,我有兩個型號:
CarType.cs
//
// Holds types of car - this has a one to many relationship with Car class
//
[Table("tType")]
public class CarType
{
[Key]
public int type_id { get; set; }
public int dealer_id { get; set; }
public string type_name { get; set; }
public string type_desc { get; set; }
public virtual ICollection<Car> Cars { get; set; }
}
Car.cs
//
// Holds actual Cars
//
[Table("tCar")]
public class Car
{
[Key]
public int car_id { get; set; }
public int dealer_id { get; set; }
public int type_id { get; set; }
public int car_order { get; set; }
public string car_name { get; set; }
public virtual ICollection<Rental> Rentals { get; set; }
public virtual CarType CarType { get; set; }
}
我想有一個視圖模型,在那裏我可以查看汽車類型和多少各車種我有每個車型類別中,所以我創建了一個視圖模型:
public class SearchViewModel
{
[Required]
public DateTime From { get; set; }
public int Nights { get; set; }
public int dealer_id { get; set; }
public IQueryable<CarType> CarTypes { get; set; }
// CarTypes as above, has a one to many relationship with the class Car
}
鑑於實際汽車(說preBookedCars),我想刪除的predeterminded列表列表o f起的的ViewObject汽車如此,例如,如果CarType(包括一個2很多車)的模型是這樣的:
Mercedes (count = 3)
....Car 1
....Car 2
....Car 3
Ford (count = 3)
....Car 4
....Car 5
....Car 6
Citroen (count = 3)
....Car 7
....Car 8
....Car 9
鑑於汽車列表,我將如何排除汽車的名單從CarType模型 - 例如。
我的列表:租車1,租車4,汽車8,租車9 - 所以我想上面的模型顯示:
Mercedes (count = 2)
....Car 2
....Car 3
Ford (count = 2)
....Car 5
....Car 6
Citroen (count = 1)
....Car 7
我知道這是沿(僞LINQ東西線):
var freeCars = (db context).CarTypes
.Cars
.Except(preBookedCars)
感謝您的幫助,
