"A namespace cannot directly contain members such as fields or methods"

I am trying to use this code for NET.reflector using Reflexil. I am trying to replace code with this:

if(Input.GetKeyDown(KeyCode.Keypad5)) { 
int i = 0; 
Character localPlayer = PlayerClient.GetLocalPlayer().controllable.GetComponent<Character>(); 
foreach (UnityEngine.Object obj2 in UnityEngine.Object.FindObjectsOfType(typeof(LootableObject))) 
{ 
    if (obj2 != null) 
    { 
        i++; 
        LootableObject loot = (LootableObject) obj2; 
        Debug.Log("Loot "+i+": "+loot.transform.position.ToString()); 
        CCMotor ccmotor = localPlayer.ccmotor; 
        if(ccmotor != null && tpPos1 != Vector3.zero) { 
            ccmotor.Teleport(loot.transform.position); 
            Notice.Popup("", "Teleported to "+loot.name, 1.5f); 
        } 
        break; 
    } 
} 

}

But it gives me an error when I try to compile:

Line: 1 Column: 1 Error Number: CS0116	Error Message: "A namespace does not directly contain members such as fields or methods"

This is Unity code I think. I am not that experienced. Could anyone fix this for me? Or tell me what to do? Thanks!

The snippet you're showing doesn't seem to be directly responsible for the error.

This is how you can CAUSE the error:

namespace MyNameSpace
{
   int i; <-- THIS NEEDS TO BE INSIDE THE CLASS

   class MyClass
   {
      ...
   }
}

If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }.
