How to correctly handle NullReferenceException when using GetComponent<>?

Question

I have tried using:

 TestComponent temp = gameObject.GetComponent<TestComponent >();
                if (temp != null)
                 {
                    //...do things
                  }

However, it gives me an error when I first try to use GetComponent.

I can suppress the error with try/catch block, but what is the way to handle it if I do not have a way to be sure that the object has specific component?

I usually run the null check before the declaration. Like this

if (GetComponent() != null) { rBody2D = GetComponent(); }

this way will it will not try to assign rBody2D to null which throws error.

I keep trying to wrap the code correct but it is not working at all for me right now. Sorry for the shotty formating
