You should now have an understanding of covariance and contravariance as it applies to delegates. The same principles apply to interfaces, including the syntax using the out and in keywords in the interface declaration. The following code shows an example of using covariance with an interface. The things to note about the code are the following: The code declares a generic interface with type parameter T. The out keyword specifies that the type parameter is covariant. Generic class SimpleReturn implements the generic interface. Method DoSomething shows how a method can take an interface as a parameter. This method takes as its parameter a generic IMyIfc interface constructed with type Animal. The code works in the following way: The first two lines of Main create and initialize a constructed instance of generic class SimpleReturn, using class Dog. The next line assigns that object to a variable on the stack that is declared of constructed interface type IMyIfc<Animal>. Notice several things about this declaration: The type on the left of the assignment is an interface type not a class. Even though the interface types don t exactly match, the compiler allows them because of the covariant out specifier in the interface declaration.

So, if the user presses the Enter button, the currently active menu is moved from Active to Ending mode, and the menu to which the selected item links is returned to the main program If the user presses the Escape button, null is returned, which will be captured later to exit the application If nothing is selected, the menu returns itself, informing the main program that this menu is still the active one..

The previous two sections explained explicit covariance and contravariance. There is also a situation where the compiler automatically recognizes that a certain constructed delegate is covariant or contravariant and makes the type coercion automatically. That happens when the object hasn t yet had a type assigned to it. The following code shows an example. The first line of Main creates a constructed delegate of type Factory<Animal> from a method where the return type is a Dog object, not an Animal object. In creating this delegate, the method name on the right side of the assignment operator doesn t yet have a type, and the compiler can determine that the method fits the type of the delegate except that its return type is of type Dog rather than type Animal. The compiler is smart enough to realize that this is a covariant relation and creates the constructed type and assigns it to the variable. Compare that with the assignments in the third and fourth lines of Main. In these cases, the expressions on the right side of the equals sign already have a type and therefore need the out specifier in the delegate declaration to signal the compiler to allow them to be covariant. class Animal { public int Legs = 4; } class Dog : Animal { } class Program { delegate T Factory<out T>(); static Dog MakeDog() { return new Dog(); } static void Main() { Factory<Animal> animalMaker1 = MakeDog; Factory<Dog> dogMaker = MakeDog; Factory<Animal> animalMaker2 = dogMaker; Factory<Animal> animalMaker3 = new Factory<Dog>(MakeDog); } } This implicit coercion implementing covariance and contravariance has been available without the in/out keywords since before C# 4.0. // Base class // Derived class
