How do I know what type of GameObject my script is attached to?

I'm currently working on a simple script in C# that I want to execute differently depending either it is attached to a Camera or any other GameObject in my scene.

I thought making a type test on the GameObject would work like so:

void Update() { if(this.gameObject.GetType() == typeof(Camera)) DoSomethingToCamera(); else DoSomethingElse(); }

But it actually doesn't.

How can I achieve this please? Thanks
