In Java I can check if a method named "addNumbers" exists in a class "Calculate" by doing this:
Class<?> c = Class.forName("com.example.package.Calculate");
Method m = c.getMethod("addNumbers", int.class, int.class);
m.invoke(5,7)
What is the C# equivalent for this example?

Java 8 has Optional<T> which is nice way to declare optional types as described here.
Is there an equivalent way to that in C# ?
