Your method CloseDoor() in the file Form1.cs needs changing. One solution is
as follows (see code). Caveat: the variable imagePath requires a valid path
to a file, otherwise an exception will be thrown on the following line.

private void CloseDoor()
    for (I = 0; i < 10; i++)
      string imgPath = myElevator.CloseElevatorDoor(i).ToString();
      Bitmap bgImage = new Bitmap(imgPath);
      pbxFloor0.BackgroundImage = bgImage;

You could contract this to a single line as follows, but I've left it as
three lines in the interests of clarity.

pbxFloor0.BackgroundImage = new

Let me know if this solves your problem!
