Netduino--讀取按鈕狀態控制LED亮(或滅)

netduino控制板上內建一個按鈕，還有一個LED可供程式控制

例如以下程式，就可以讀取按鈕狀態，按下按鈕時LED會亮，放開按鈕LED熄滅
 
public static void Main()
        {
            // write your code here
            OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);
            InputPort button = new InputPort(Pins.ONBOARD_SW1, false, Port.ResistorMode.Disabled);
            bool buttonState = false;
            while (true)
            {
                buttonState = button.Read();
                led.Write(!buttonState);
            }
        }
