How do i remove the the object when it matched? #C

I follow a tutorial on Augmented Reality code. I want to remove the object (mid1 & mid2) when it matched together. Someone please help me.

public class SimpleLiteMBehaviour : MonoBehaviour
{

      private NyARUnityMarkerSystem markerSystem;

      private NyARUnityWebCam displayMarker;

      private int mid1;

      private int mid2;

      private GameObject baseObject;

      private int Score = 0;

void Awake()
{

	WebCamDevice[] devices= WebCamTexture.devices;
	WebCamTexture w;
	if (devices.Length > 0)
	{
		w=new WebCamTexture(640, 480, 30);
		this.displayMarker=new NyARUnityWebCam(w);

		NyARMarkerSystemConfig config = new NyARMarkerSystemConfig(w.requestedWidth,w.requestedHeight);
		this.markerSystem=new NyARUnityMarkerSystem(config);

		mid1=this.markerSystem.addARMarker(
			new StreamReader(new MemoryStream(((TextAsset)Resources.Load("patt_hiro",typeof(TextAsset))).bytes)),
			16,25,80);

		mid2=this.markerSystem.addARMarker(
			new StreamReader(new MemoryStream(((TextAsset)Resources.Load("patt_kanji",typeof(TextAsset))).bytes)),
			16,25,80);

		this.baseObject=GameObject.Find("Plane");
		this.baseObject.renderer.material.mainTexture=w;
		this.markerSystem.setARBackgroundTransform(this.baseObject.transform);
		

		this.markerSystem.setARCameraProjection(this.camera);	
	}
	else
	{
		Debug.LogError("No Webcam.");
	}
}

void Start ()
{

	this.displayMarker.start();
}

void Update ()
{

	this.displayMarker.update();

	this.markerSystem.update(this.displayMarker);

	if(this.markerSystem.isExistMarker(mid1))
	{
		this.markerSystem.setMarkerTransform(mid1,GameObject.Find("MarkerObject").transform);
	}
	else
	{

		GameObject.Find("MarkerObject").transform.localPosition=new Vector3(0,0,-100);
	}

	if(this.markerSystem.isExistMarker(mid2))
	{
		this.markerSystem.setMarkerTransform(mid2,GameObject.Find("MarkerObject2").transform);
	}
	else
	{

		GameObject.Find("MarkerObject2").transform.localPosition=new Vector3(0,0,-100);
	}

	if((this.markerSystem.isExistMarker(mid1)) && (this.markerSystem.isExistMarker(mid2)))
	{  
		Score = Score+1;
		Debug.Log ("Same! Score : "+Score, gameObject);

		//gameObject.renderer.enabled = false;

		//gameObject.active = false;
	

	}
}

}

Try:

GameObject.Destroy(this.gameObject);
