Unity - how to find the 3 closest objects from an array?

Question

C++ / C#

So I wrote such a code, but firstly it is resource-intensive, and secondly, it finds the distance only to the nearest object.
Added objects to the array:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Rasstoyanie : MonoBehaviour
{
    GameObject[] enemy;
    GameObject player;
    public string nearest;

    private void Start()
    {
        enemy = GameObject.FindGameObjectsWithTag("Enemy");
    }
}

and in this part you need to find instead of 1 object, the 3 closest ones:

GameObject Find()
    {
        float dist = Mathf.Infinity;
        Vector3 position = transform.position;
        foreach(GameObject go in enemy)
        {
            Vector3 diff = go.transform.position;
            float currdist = diff.sqrMagnitude;
            if(currdist < dist)
            {
                player = go;
                dist = currdist;
            }        
        }
        return player;  
    }

can you correct and suggest how to find the next 3 objects? Just the first time I encountered arrays.

Answer 1

It is necessary to make a parser from for. It will check each object in the array and then you need to take data from each object.
