You can see classes as a template or blueprint from which to make (instantiate) objects.

Take for example a class Car which has some properties (speed, color, ...) that define it and some methods that make it do things (accelerate(), turn(), ...).

to make use of a "car" you need to define one (instantiate):
C#
Car lambo = new Car();
Car volvo = new Car();
In this case we instantiated 2 (different!) objects based on the class (or template) "Car".

When it gives you the error you have, it means you're trying to call an object which has not yet been created.

Hope this helps.
