How do I shorten a gameObject.GetComponent

Question

 spawned.GetComponent<Button>().onClick.AddListener(delegate { gameObject.GetComponent<controller>().UpdateFeed("whatever"); });

This code here puts a listener on my button and interacts with another script, but I, for the life of me, cannot figure out how to shorten the "gameObject.GetComponent()" part as to not waste space when adding listeners to other buttons. How do I shorten it?

Methods that return a value can just be treated like that value in situ.

So

  int myInt = 0;

And

  int GetMyInt()
  {
      return 0;
  }

Are equivalent in use

i.e

  myInt.ToString();

// and

  GetMyInt().ToString();

Both evaluate to the same outcome i.e. a string with a value of "0"

With that in mind you can store the output of methods into variables..

So you can do:

  var myComponent = gameObject.getComponent();

And then you can just reference the object by using the variable.

Does that make sense?

If you are going to store it somewhere you need to store it in a context/scope which doesnt deallocate it. So on the instance of a component would be a good place. If you declare it inline you will lose it as soon as the you finish executing that method.
