c# Linq, how return query with ENUM

Question

So from Front-end I get a string "test1,test2,test3" or "test1,test2" etc. (I can change this on number, it is not a problem);

In back-end I have this:

class Car 
{
    public int Id { get; set; }
    public string Name { get; set; }
    public Color Color { get; set; }
}
    
public enum Color
{
    Red = 1,
    Blue = 2,
    Pink = 3,
    Orange = 4,
}

public async Task<Car> GetAllCars(string searchString)
{
    switch (searchString)
    {
        case "How create here query guestion whcih inlude ENUMS":
            query = query.Where( inlude x=> a.Color == x.Contains(x.Color))
        break;

        default:
            query = query.Where(at => 
                    at.Id.ToString().Contains(searchString)
                ||
                    at.Name.Contains(searchString));
         break;
    }
}

I want return all query which have the same enums

If you want to return all cars, then you need to change the return type to List and then lets assume that you have some list of cars (List<Car>) and we should pick cars from there by name and color:

public async Task<List<Car>> GetAllCars(string searchString)
{
    return cars.Where(x=>x.Name.Contains(searchString) || x.Color.ToString().Contains(searchString).ToList();
}
