//It's worth noting that a lot of the power of reflection comes from the fact that you
//don't necessarily need to know what class you're dealing with. C# has a feature called
//"generics" that allows you to create methods that don't have a specific parameter type,
//or that return different types. It works like this:
PrintOutPropertyValues_Generic(instance); //this looks the same, but check out the method
Console.ReadKey(); //pause so you can see the results
