Can anyone translate this to C# (Change cursor appearance)

Hello guys. I Want to change cursor appearance for my game. I found this useful script from another answer and it works perfectly. The only problem is that it is witten in Java. Can anyone translate this into C#

    var cursorImage : Texture;

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

function OnGUI() {
    var mousePos : Vector3 = Input.mousePosition;
    var pos : Rect = Rect(mousePos.x,Screen.height - mousePos.y,cursorImage.width,cursorImage.height);
    GUI.Label(pos,cursorImage);
}

Thank you for your time.

public Texture cursorImage;

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

public void OnGUI()
{
    Vector3 mousePos = Input.mousePosition;
    Rect pos = new Rect(mousePos.x, Screen.height - mousePos.y, 
        cursorImage.width, cursorImage.height);
    GUI.Label(pos, cursorImage);
}
