Hi. Here is a code which basically detects if an object is clicked by using the box colliders and then moves to the next level accordingly. I need help in converting this script to c#. Please help me out.

	if (Input.GetMouseButtonDown (0)) {
		var ray = Camera.main.ScreenPointToRay (Input.mousePosition); //typical mouse click input
		var hit:RaycastHit;
	if (Physics.Raycast (ray, hit, 20)) {
		
		if(hit.collider.name == "Level1Collider") //this is all of our code for triggering loading levels when a collider is clicked on
		Application.LoadLevel("level1");
		
		if(hit.collider.name == "Level2Collider")
		Application.LoadLevel("level2");
		
		if(hit.collider.name == "Level3Collider")
		Application.LoadLevel("level3");
		}
	}

if (Input.GetMouseButtonDown(0))
{
    Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); //typical mouse click input
    RaycastHit hit;
    if (Physics.Raycast(ray, out hit, 20))
    {
            if (hit.collider.name == "Level1Collider") //this is all of our code for triggering loading levels when a collider is clicked on
            Application.LoadLevel("level1");

            if (hit.collider.name == "Level2Collider")
                Application.LoadLevel("level2");

            if (hit.collider.name == "Level3Collider")
                Application.LoadLevel("level3");
    }
