hi guys, i just created a raycast script that opens a door when the hit collider hits the door. The script i made was done in java now the thing is that i now want to take this script and make the same thing in C sharp. But as soon as i tried that i came across a problem, basically in the update function in my java script i created a variable called :

  var Hit: RaycastHit;

now in C sharp if i try to make the same variable it wont work what is the correct way to put this right in C#

here are my scripts :

JAVA:

      var RayCastDist  = 5;

          function Update () {

             var hit : RaycastHit;

           Debug.DrawRay (transform.position, Vector3.forward * RayCastDist, Color.green); 
                if(Physics.Raycast(transform.position,Vector3.forward, hit, RayCastDist))


       {
             Debug.DrawRay (transform.position, Vector3.forward * RayCastDist, Color.red);
                  if(hit.collider.gameObject.tag == "door"){

                        hit.collider.gameObject.animation.Play("Door animation");

      }
    }
   }

That was the Java script here is the C sharp :

    using UnityEngine;
       using System.Collections;

       public class OpenDoorScriptRayCSharp : MonoBehaviour {

             public float RayCastHitDoor  = 5;

         // Update is called once per frame
           void Update () {




       }
      }

So yea thats the scripts and thanks in advance :)
