如何使用Windows 10 IoT uwp c＃运行LED

我在使用Raspberry PI 3 Windows IOT创建运行LED时遇到问题，但是随机LED闪烁确实有效。  两者的代码几乎相同，只有不同的运行LED由变量计数和随机LED控制  用随机生成器生成。

正在运行的led代码位于此文本下方。我将只得到第一个导致光，其余的LED保持黑暗。有人能看出这段代码有什么问题吗？  但随机闪烁导致工作，这在运行的LED代码和两个代码几乎相同之后，但仍然运行的LED代码不起作用。

我将只得到第一个导致光线，其余的LED保持黑暗。   有人能看出这段代码有什么问题吗？

因为每次输入Timer_Tick()，ledValue2变量都会在此行初始化为0：

 int ledValue = 0, ledValue2 = 0;

您需要从ledValue2移出Timer_Tick()变量。例如，您可以将它放在MainPage类的开头。并在此代码行ledValue2 = ledValue2 + 1之后添加以下代码。

        if (ledValue2 > 7)
        {
            ledValue2 = 0;
        }
