C#

Hello everybody,
If i used ClickOne, where could i say the path the program has to be installed in the user pc?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class moviment1 : MonoBehaviour
{
    public float Speed;
    public float JumpForce; 

    public bool isJumping;
    public bool doubleJump;

    private Rigidbody2D rig;
    
    // Start is called before the first frame update
    void Start()
    {
      rig = GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void Update()
    {
        Move();
        Jump();
    }
   //  MOVE 

    void Move()
    {
        Vector3 movement = new Vector3(Input.GetAxis("Horizontal"), 0.0f, 0.0f);
        transform.position += movement * Time.deltaTime * Speed;
    }
  
     // JUMP
    void Jump()
    {
        if (Input.GetButtonDown("Jump") )
        {
            if(!isJumping)
            {
           
         rig.AddForce(new Vector2(0.0f, JumpForce), ForceMode2D,Impulse);
        doubleJump = true;
        }
          else
          {
             if(doubleJump)
             {
                rig.AddForce(new Vector2(0.0f, JumpForce), ForceMode2D,Impulse);
           doubleJump = false;
    }
    }
    }
    }      
       void OnCollisionEnter2D(Collision2D collision)
       {
         if(collision.gameObject.layer == 8)
         {
             isJumping = false;
         }
       }
       void OnCollisionExit2D(Collision2D collision)
       {
          if(collision.gameObject.layer == 8)
      {  

         isJumping = true;
   }
  
       } 

Hello, I want to apply this code, with an example. But I can't apply this class because it will show me that I don't have it. What should I do?

using Windows.Devices.Enumeration;
using Windows.Devices.HumanInterfaceDevice;

public class MyBase
{
   public string CommonProperty { get; set; }
}

public class ClassOne : MyBase
{
   public string  ClassOneProperty { get; set; }
}

public class ClassTwo : MyBase
{
   public string ClassTwoProperty { get; set; }
}

public class program()
{
   var classTwo = new ClassTwo();
   classTwo.CommonProperty = "Some string";
   classTwo.ClassTwoProperty = "Some other string";
   TestFunction(classTwo);

   private void TestFunction(object unknownClass)
   {
       // how do I convert unknownClass to its actual class and access its properties
       // regardless of which type was passed to the function?
   }
}
