这是this post排除某个模型项目 - MVC/ASP.Net
一个跟进的问题,我有两个型号:
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; }
}
我想有一个视图模型,在那里我可以查看汽车类型和多少各车种我有每个车型类别中,所以我创建了一个视图模型:
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
}
鉴于实际汽车(说preBookedCars),我想删除的predeterminded列表列表o f起的的ViewObject汽车如此,例如,如果CarType(包括一个2很多车)的模型是这样的:
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
鉴于汽车列表,我将如何排除汽车的名单从CarType模型 - 例如。
我的列表:租车1,租车4,汽车8,租车9 - 所以我想上面的模型显示:
Mercedes (count = 2)
....Car 2
....Car 3
Ford (count = 2)
....Car 5
....Car 6
Citroen (count = 1)
....Car 7
我知道这是沿(伪LINQ东西线):
var freeCars = (db context).CarTypes
.Cars
.Except(preBookedCars)
感谢您的帮助,
