How to use the cursor.visible

I am using Unity 5 and I need to convert some old work. I got this so far in C#

  using UnityEngine;
    using System.Collections;
    
    public class Cursorhide : MonoBehaviour {
    	Cursor.visible = false;

}

inside the class Cursorhide add this

void Start ()
{
    Screen.showCursor = false;
}
