Assigning class instance to a Gameobject

 using System;
 using System.Collections.Generic;
 using UnityEngine;
  
  public class MyScript : MonoBehaviour
  {
      public MyScript()
      {
          Camera.main.backgroundColor = Color.red;
      }
     void Update()
     {
         #region Behavior Bouncy
         //Some bouncy code
         #endregion
     }
  }

Hi, I am compiling this code snippet from my EditorWindow using CSharpCodeProvider. The code compiles fine from the EditorWindow. But I was wondering if I can assign this MyScript or any instance of that, to my Gameobject so it could use my Update. I am really sorry if the question doesnt seem legit. I am still figuring things out. Thanks.
