Move an object towards closest enemy.

Hey guys I found a code in the unity reference that finds the closest object to the player and im trying to figure out how i could move the object towards closest object in the array. Everything i tried gives me an error so far. I was wondering if anyone could quickly point me to the right direction.

 using UnityEngine;
 using System.Collections;
 
 public class projectileMove : MonoBehaviour 
 {
     float projectileSpeed = 0;
     void Update()
     {
         float projSpeed = projectileSpeed * Time.deltaTime;
         //FindClosestEnemy();
         print (FindClosestEnemy().name);
         //transform.position = Vector3.MoveTowards(transform.position, FindClosestEnemy().position, projSpeed);
     }
     GameObject FindClosestEnemy()
     {
         GameObject[] gos;
         gos = GameObject.FindGameObjectsWithTag("Enemy");
         GameObject closest = null;
         float distance = Mathf.Infinity;
         Vector3 position = transform.position;
         foreach (GameObject go in gos) 
         {
             Vector3 diff = go.transform.position - position;
             float curDistance = diff.sqrMagnitude;
             if (curDistance < distance) 
             {
                 closest = go;
                 distance = curDistance;
             }
         }
         return closest;
     }
 }
