// Define a delegate pointing to methods that return Car types.

public delegate Car ObtainCarDelegate();

Of course, you would be able to define a target for the delegate as expected:

class Program

{

public delegate Car ObtainCarDelegate();



public static Car GetBasicCar()

{ return new Car("Zippy", 150, 50, false, false); }

static void Main(string[] args)

{

ObtainCarDelegate targetA = new ObtainCarDelegate(GetBasicCar);



Car c = targetA();

Console.WriteLine("Obtained a {0}", c);

Console.ReadLine();

}

}



Now, what if you were to derive a new class from the Car type named SportsCar and wish to

create a delegate type that can point to methods returning this class type? Prior to .NET 2.0, you

would be required to define an entirely new delegate to do so, given that delegates were

so type

safe that they did not honor the basic laws of inheritance:
