C# - with a reference to a base class, how can I access a property of the inherited class if I know that my reference is to the inherited class?

Question

I'd like to do something like the following with my code:

BaseClass class;

if (BaseClass is InheritedClass)
{
    class.MethodOnlyInInheritedClass();
}

However I get an error that BaseClass does not contain a definition for MethodOnlyInInheritedClass. It doesn't, but I know based on the previous test that my particular reference to BaseClass is an inherited type that DOES contain that method. I tried casting class as InheritedClass but that didn't work.

Is there a way to do what I'm seeking?

Looks to be compile time error does not contain definition for...

Define MethodOnlyInInheritedClass as a virtual method in your base class (or have it as an abstract method in abstract base class) and override same in InheritedClass
