Help me Convert JS to C#

Hello, i'm beginner to unity, and i only use Javascript, today i was forced to convert my js script to C#, always fails when because i don't know much about arrays, this is the JS

 var waypointContainer : GameObject;
 private var waypoints : Array;
 private var currentWaypoint : int = 0;
 
 function Start () {
     var potentialWaypoints : Array = waypointContainer.GetComponentsInChildren( Transform );
 
     waypoints = new Array();
 
     for ( var potentialWaypoint : Transform in potentialWaypoints ) {
 
     if ( potentialWaypoint != waypointContainer.transform ) {
     waypoints[ waypoints.length ] = potentialWaypoint;
     }
 
     }
 }
 
 function Update () {
 
 }
 
 function NavigateToWaypoint () {
 var RelativeWaypointPosition : Vector3 = transform.InverseTransformPoint( Vector3( waypoints[currentWaypoint].position.x, transform.position.y, waypoints[currentWaypoint].position.z ) );
 //AxisCarController.steerAI = RelativeWaypointPosition.x / RelativeWaypointPosition.magnitude;
 
 if ( RelativeWaypointPosition.magnitude < 15 ) {
 currentWaypoint ++;
 
 if ( currentWaypoint >= waypoints.length ) {
 currentWaypoint = 0;
 }
 
 
 }
 }

And this is the C# script

 using UnityEngine;
 public class GetWayPoint : MonoBehaviour
 {
     // Fields
     private int currentWaypoint;
     public GameObject waypointContainer;
     private Array waypoints;
 
     // Methods
     public override void Main()
     {
     }
 
     public override void NavigateToWaypoint()
     {
         if (this.get_transform().InverseTransformPoint(new Vector3(RuntimeServices.UnboxSingle(UnityRuntimeServices.GetProperty(UnityRuntimeServices.GetProperty(this.waypoints.get_Item(this.currentWaypoint), "position"), "x")), this.get_transform().get_position().y, RuntimeServices.UnboxSingle(UnityRuntimeServices.GetProperty(UnityRuntimeServices.GetProperty(this.waypoints.get_Item(this.currentWaypoint), "position"), "z")))).get_magnitude() < 15)
         {
             this.currentWaypoint++;
             if (this.currentWaypoint >= this.waypoints.get_length())
             {
                 this.currentWaypoint = 0;
             }
         }
     }
 
     public override void Start()
     {
         Array componentsInChildren = this.waypointContainer.GetComponentsInChildren(typeof(Transform));
         this.waypoints = new Array();
         IEnumerator enumerator = UnityRuntimeServices.GetEnumerator(componentsInChildren);
         while (enumerator.MoveNext())
         {
             object obj1 = enumerator.get_Current();
             if (!(obj1 is Transform))
             {
             }
             Transform transform = RuntimeServices.Coerce(obj1, typeof(Transform));
             if (transform != this.waypointContainer.get_transform())
             {
                 this.waypoints.set_Item(this.waypoints.get_length(), transform);
                 UnityRuntimeServices.Update(enumerator, transform);
             }
         }
     }
 
     public override void Update()
     {
     }
 }
 

it's giving me the error that the namespace Array couldn't be found.

Please help me :(
