验证考试表单

验证选择题测试的答案并计算分数（创建考试表单的延续）：

• 使用单选按钮选项重建考试表单结构（Api/CreateCheckBoxForm、ApiCheckBoxForm/SetRadioGroup）；
• 预填示例答案用于演示（ApiCheckBoxForm/SetChecked）；
• 遍历所有表单并验证答案（ApiDocument/GetAllForms、ApiFormBase/GetFormType）；
• 检查所选选项并与正确答案比较（ApiCheckBoxForm/IsChecked、ApiFormBase/GetFormKey）；
• 获取表单提示文本以提供详细反馈（ApiFormBase/GetTipText）。

• Code
• Result
