Using the parameters of a method automatically

I'm using a state machine that is class based.

Here's an example of my one of my states:

Code (CSharp):

1. public class JumperPatrol : State<EnemyJumperAI>
2. {
3.     public static JumperPatrol Instance = new JumperPatrol();
4.  
5.     public override void Enter(EnemyJumperAI _c)
6.     {
7.         _c.CurrDir = Random.Range(0, 2) == 0 ? Vector2.left : Vector2.right;
8.     }
9.  
10.     public override void Execute(EnemyJumperAI _c)
11.     {
12.         _c.ChangeDirectionDependingOnTerrain();
13.  
14.         if (_c.FacingTheTarget() && _c.DistanceToTarget() <= _c.DistanceBeforeAttack)
15.         {
16.             _c.Fsm.ChangeState(JumperJumpAttack.Instance);
17.         }
18.     }
19.  
20.     public override void Exit(EnemyJumperAI _c)
21.     {
22.     }
23. }

As you can see, I constantly have to call the methods from the parameter called "_c", is there a way for me to skip that part where I constantly have to write out _c?

To explain this in different words: I want to keep the same behaviour as I do right now, I just would like not to have to write _c every time I use something because it makes it harder to understand the code. How can I achieve that?
