Check that value exists in a Generic List of Values

Question

I am trying to figure out how to check if testInt exists in all Car.SomeID in List

So:

int testInt = 10;
List<Car> myCars = GetCars();

I want to see if there is a match on 10 in any of myCards.SomeID

Answer 1

In the more general case, with LINQ (supports any type of abstract typed list):

bool hasCar = myCars.Any(c => c.SomeID == testInt);
