An object reference is required to access non-static member `UnityEngine.Component.GetComponent(System.Type)

Okay, I’m trying to make a door visible by turning on the mesh renderer, so I made this code, but I’m getting this error: Assets/scripts/NewDoor.cs(18,35): error CS0120: An object reference is required to access non-static member `UnityEngine.Component.GetComponent(System.Type)’

The script (in c#)

using UnityEngine;
    using System.Collections;
    
    public class Newdoor : MonoBehaviour {
    	GameObject [] dr;
    
    
    	// Use this for initialization
    	void Start () {
    	
    	}
    	
    	// Update is called once per frame
    	void Update () {
    		dr = GameObject.FindGameObjectsWithTag("door");
    		foreach(GameObject go in dr){
    			go.Component.GetComponent(renderer);
    			renderer.enabled = true;
    		}
    	}
    }

I get the error is on line 18, and I’m sure that it’s a very easy answer, but I just don’t get it.
Please help, I’m trying to do this for a class.
Thanks in advance for your help!

Here’s a fixup of your code:

using UnityEngine;
using System.Collections;

public class Newdoor : MonoBehaviour {
	GameObject [] dr;

	void Update () {
		dr = GameObject.FindGameObjectsWithTag("door");
		foreach(GameObject go in dr){
			Renderer rend = go.GetComponent<Renderer>();
			if (rend != null)
				rend.enabled = true;
		}
	}
}

If you are sure that every object tagged ‘door’ will have a renderer, you can get red of the null check and just do:

  foreach(GameObject go in dr){
      go.GetComponent<Renderer>().enabled = true;
   }
