Error CS0120

I tried looking at other CS0120 errors but those didn’t help me in my problem.

using System;
using UnityEngine;

[Serializable]
public class PlayerScripts : MonoBehaviour
{
    public float gameTime = 20f;
    public int length = 20;
    public int length2 = 0x23;
    public float LevelWaitTime = 2;
    public string name = "game time";
    public string name2 = "Score";
    public int PointsToWin = 20;
    public float rayDistance;
    public int score;
    public string tagName;
    public int width = 100;
    public int width2 = 100;
    public int xpos = 10;
    public int xpos2 = 10;
    public int ypos = 10;
    public int ypos2 = 0x19;

	public void Start()
	{
		InvokeRepeating("CountDown", 1f, 1f);
	}

	public void Update()
	{
		if (Input.GetMouseButtonDown(0))
		{
				Debug.Log("Pressed left click.");
				RaycastHit hit = new RaycastHit();

			//if (Physics.Raycast(Camera.get_main().ScreenPointToRay(Input.get_mousePosition()), ref hit, rayDistance) && (hit.get_transform().get_tag() == tagName))
//			if(hit.transform.tag ==tagName)
//			{
//				EnemyScriptCsharp = hit.transform.GetComponents(typeof(EnemyScriptCsharp));
//				EnemyScriptCsharp.numberOfClicks -= 1;
//				
//				if(EnemyScriptCsharp.numberOfClicks == 0)
//				{
//					score += EnemyScriptCsharp.enemyPointWorth;
//				}	
//			}
			if (hit.transform.tag == tagName)
			{
				hit.transform.GetComponent(typeof(EnemyScriptCsharp));
				EnemyScriptCsharp.numberOfClicks --;                //here error CS0120
				if (EnemyScriptCsharp.numberOfClicks == 0)			//here error CS0120
				{
					score += EnemyScriptCsharp.enemyPointWorth;		//here error CS0120
				}
			}
		}
	}

	public void CountDown()
	    {
	        if (--gameTime == 0)
	        {
	            CancelInvoke("CountDown");
	            if (score >= PointsToWin)
	            {
	                Application.LoadLevel("sceneScreenWinMenu");
	            }
	            else
	            {
	                Application.LoadLevel("sceneScreenLoseMenu");
	            }
	        }
	    }
	
    public void OnGUI()
    {
        GUI.Label(new Rect((float) xpos, (float) ypos, (float) width, (float) length), "Score: " + score);
        GUI.Label(new Rect((float) xpos2, (float) ypos2, (float) width2, (float) length2), "GameTime: " + gameTime);
    }
   
}

And Here is the section with the error

if (hit.transform.tag == tagName)
			{
				hit.transform.GetComponent(typeof(EnemyScriptCsharp));
				EnemyScriptCsharp.numberOfClicks --;                //here error CS0120
				if (EnemyScriptCsharp.numberOfClicks == 0)			//here error CS0120
				{
					score += EnemyScriptCsharp.enemyPointWorth;		//here error CS0120
				}
			}

and here is what it is suppose to reference

using UnityEngine;
using System.Collections;
public class EnemyScriptCsharp : MonoBehaviour
{
    public int enemyPointWorth = 1;
    public Transform explosion;
    public int numberOfClicks = 2;
    public float respawnWaitTime = 2f;
    public Color[] shapeColor;
    private int storeClicks = 0;

    // Methods

    public void RandomColor()
    {
        if (shapeColor.Length > 0)
        {
            int newColor = Random.Range(0,shapeColor.Length);
            renderer.material.color = shapeColor[newColor];
        }
    }

     

    public void Start()
    {
        storeClicks = numberOfClicks;
        Vector3 startPosition = new Vector3( Random.Range(-6, 6), Random.Range(-4.5f, 4.5f), 0);
        transform.position = startPosition;
        RandomColor();
    }

    public void Update()
    {			
        if (numberOfClicks <= 0)
        {
            if (explosion)
            {
                Instantiate(explosion,transform.position,transform.rotation);
            }
          
			Vector3 position = new Vector3(Random.Range(-6, 6), Random.Range(-4.5f, 4.5f), 0);
            RespawnWaitTime();
            transform.position = position;
            numberOfClicks = storeClicks;
        }
    }
	
	//public 
	IEnumerator RespawnWaitTime()
    {
        renderer.enabled = false;
 		RandomColor();
 		yield return new WaitForSeconds(respawnWaitTime);
 		renderer.enabled = true;
    }
}

You are not saving the reference you get back from GetComponent(), and you are using the Class to try and access instance variables.

Try this:

		if (hit.transform.tag == tagName)
		{
			EnemyScriptCsharp escs = hit.transform.GetComponent<EnemyScriptCsharp>();
			escs.numberOfClicks--;                //here error CS0120
			if (escs.numberOfClicks == 0)       //here error CS0120
			{
				score += escs.enemyPointWorth;       //here error CS0120
			}
		}
