在类里面使用enum里面的struct？

public class Car
{
    public enum EngineType
    {
        Gasoline,
        Diesel,
        Electric
    }

    public struct Engine
    {
        public EngineType Type;
        public int Horsepower;
        public int Torque;
    }

    public Engine EngineInfo;
    public string Make;
    public string Model;
    public int Year;

    public Car(EngineType engineType, int horsepower, int torque, string make, string model, int year)
    {
        EngineInfo.Type = engineType;
        EngineInfo.Horsepower = horsepower;
        EngineInfo.Torque = torque;
        Make = make;
        Model = model;
        Year = year;
    }
}
