我已经能够使用随机方法来完成我的大部分任务，即尝试随机填充标签和 RadioButtonList 项以创建 5 个问题的测验。鉴于它所提取的大量问题，该代码生成了一个很好的混合问题。
但是，随机填充 RadioButtonList 项的内部代码表现得很有趣。
当我在我的 while 循环中设置断点并逐步运行它时，答案会在下一个问题上以不同的顺序填充。
但是，当我只是打开浏览器并从我部署到的 Sharepoint 网站上运行它时，答案在每个下一个问题/所有问题上都遵循相同的顺序。注意：它确实会在页面刷新时抛出独特的订单；换句话说，当我再次开始测验时。
我似乎无法弄清楚我生命中的障碍。可以用几双眼睛。
这是迄今为止的代码：请告知
