Quick question

I'm pretty new to Unity and Programming as a whole, recently I've been trying to practice with simple animation (just switching idle to walk). I've gotten it to work in js but I'd prefer all my code to be in C#, so I'm curious how it would look.

In Java:

 #pragma strict
 
 var speed : float = 5f;
 var anim : Animator;
 function Start () {
 anim = gameObject.GetComponent(Animator);
 }
 
 function Update () {
     if(Input.GetKeyDown(KeyCode.T))
         {
         anim.SetFloat("Trigger",1); //Starts walk animation
         }
     else
         {
         anim.SetFloat("Trigger",0); //Otherwise loop idle animation
         }
 }

What I tried:

 using UnityEngine;
 using System.Collections;
 
 public class Testing : MonoBehaviour {
 
     private float speed = 5f;
     private Animator anim;
 
 
     void Start () {
         anim = gameObject.GetComponent(Animator);
     }
     
     void Update () {
         if(Input.GetKeyDown(KeyCode.T))
         {
             anim.SetFloat("Trigger",1); //Starts walk animation
         }
         else
         {
             anim.SetFloat("Trigger",0); //Otherwise loop idle animation
         }
     }
 }

It's not working, but again I'm just starting to learn to program. What should it look like in C#?
