当我选择不正确的答案时，下一个问题会加载已显示的答案

Question

我对编码和 C# 完全陌生。 我正在学习 3 级 ICT，在我的编程科目中，我们被要求对基本技能学生进行测验（使用表格）。 我被要求创建一个非常基本的登录屏幕、主题选择屏幕、级别选择屏幕，以及实际的问题和答案； 答案是按钮。

我的问题是当我选择了下一个问题的错误答案时加载但显示该问题的正确答案。

不太确定我需要做什么。 我想在周末解决这个问题，所以我无法问我的老师。

必须保持非常基本。

这是我的代码。 我感谢有关此主题的任何帮助。

Answer 1

很难准确地说，因为你粘贴的代码不足以在我这边复制它，但只是从快速扫描来看，你似乎依赖于很多状态（例如按钮位置/位置、颜色、可见性，等）保存在主窗体的每个控件中。 由于没有为每个问题重新创建表单，因此很可能在第一个问题的初始化中存在一些假设，但没有为第二个问题（和后续问题）明确正确设置。

因此，例如，如果您将 btnCorrect.BackColor 设置为绿色以获得成功答案，请确保为下一个问题（例如在 LoadQuestions() 中）将其重新初始化为红色（或您表单中的任何默认值） .
