foreach loop with an array of GameObjects

Question

I'm not sure what I am doing wrong

error CS0030: Cannot convert type UnityEngine.GameObject' to int'

Code:

 public GameObject[] enemies; //dragged 6 GameObjects into Inspector
 
 void OnTriggerEnter(Collider collider)
 {
     //activate enemies
     foreach (int i in enemies) //the line the error is pointing to
     {
         //enemies[i].active = true;    
     }
 }

The right way to do it is:

void OnTriggerEnter(Collider collider)
{
    //activate enemies
    foreach (GameObject enemy in enemies)
    {
       enemy.active = true;   
    }
}

The instruction foreach loops through all elements in the group using internal pointers or indexes; you just supply a variable of the correct type, and foreach assigns to it a new element each iteration.

Thanks. Never got the hang of foreach statements but now I think I know what they are about.

Actualization to 2019

     void OnTriggerEnter(Collider collider)
         {
             //activate enemies
             foreach (GameObject enemy in enemies)
             {
                enemy.SetActive(true);   
             }
         }
