How do I form a good predicate delegate to Find() something in my List?

Question

After looking on MSDN, it\'s still unclear to me how I should form a proper predicate to use the Find() method in List using a member variable of T (where T is a class)

Ok, in .NET 2.0 you can use delegates, like so:

static Predicate ByYear(int year)
{
    return delegate(Car car)
    {
        return car.Year == year;
    };
}

static void Main(string[] args)
{
    // yeah, this bit is C# 3.0, but ignore it - it's just setting up the list.
    List list = new List
    {
        new Car { Year = 1940 },
        new Car { Year = 1965 },
        new Car { Year = 1973 },
        new Car { Year = 1999 }
    };
    var car99 = list.Find(ByYear(1999));
    var car65 = list.Find(ByYear(1965));

    Console.WriteLine(car99.Year);
    Console.WriteLine(car65.Year);
}
