Syntax for c# to do this?

c#
 public override void _PhysicsProcess(double delta)
    {
        if (DetectCollision(Player, Floor))
        {
            Player.position
        }
    }

c#
 public override void _PhysicsProcess(double delta)
    {
        if (DetectCollision(Player, Floor))
        {
            Player.position
        }
    }
