class Car{
     int ID {get;set;}
     string Text {get;set;}
}

List<Car> allCars = new List<Car>(){ new Car{ ID = 1, Text = "one"}, new Car{ ID = 2, Text = "two"}, new Car{ ID = 3, Text = "three"}, new Car{ ID = 4, Text = "four"} };
int[] existingCarIds = new int[]{ 2, 4 };

我想有这个清单.

CarWithID2
CarWithID4
CarWithID1
CarWithID3

所以我做了:

List<Car> carList = allCars.Where(d => existingCarIds.Contains(d.ID)).Concat(allCars.Where(d => !existingCarIds.Contains(d.ID))).ToList();

有没有其他方法可以进行相同的查询？

谢谢
