推荐答案

在 button2_Click ，您忘记了案例1中的 caseswitch - 语句。您还可以通过删除重复项来大大简化此代码来自每个案例的部分，甚至可能使用辅助方法来运行播放器并设置图像。



[edit]

我的错误，如果是1，你应该设置 caseswitch = 6 。



对于重复项，你可以设置一个列出所有资源元素，并按开关的索引值选择它们。

In button2_Click, you forgot the caseswitch-- statement in case 1. You could also simplify this code considerably by removing the duplicate portions from each case, and possibly even using a helper method to run the player and set the image.

[edit]
My mistake, in case 1 you should set caseswitch = 6.

As to the duplicates, you could set up a list with all the resource elements, and select them by the index value of the switch.
