c#多选题测试

Question

我正在创建一个基于web的修订资源，我正在尝试用asp.net在c#中创建一个多项选择测验。我已经创建了它并让它工作，但它很长，想知道是否有人知道我如何使代码更紧凑，也当它打印最终分数时，它出现在我网站上的导航栏上方，我不知道为什么。

此外，答案可以更改，提交按钮只是再次点击，我找不到任何关于如何停止这一点的爱。

我对任何事情都非常陌生，并且正在尽我最大的努力。如果有人能给我指出正确的方向，或者提出一些可能有帮助的建议，那就太好了。

谢谢

我对代码的长度表示歉意：

Answer 1

这可能会缩短评估阶段：

RadioButtonList[] lists = new RadioButtonList[] {RadioButtonList1, RadioButtonList2, RadioButtonList3, RadioButtonList4, RadioButtonList5, RadioButtonList6, RadioButtonList7, RadioButtonList8, RadioButtonList9, RadioButtonList10 };

foreach (RadioButtonList element in lists ) {
            if (element.SelectedValue == "correct") {
                Score++;
        }
}

Answer 2

对于Submit_Click方法，我建议您将所有的CheckBoxes放在一个列表中或某种类型的Enumerable中。然后，您可以对此列表进行迭代，并在每次迭代中评估结果。某物类似于：

protected void Submit_Click(object sender, EventArgs e)
{
     int score = 0;
     List<RadioButtonList> list = new List<RadioButtonList>() { RadioButtonList1, RadioButtonList2, ... RadioButtonList3 };
     foreach (var element in list) 
     {
        if (element.SelectedValue == "correct") {
            score++;
     }
     Response.Write(score);
}

Answer 3

我没有一个确切的解决方案，但既然你问的是如何被指引到正确的方向，下面是你应该采取的步骤：

• 创建一个带有问题语句的TextBox和单选控件列表或任何选项的用户控件，还可以添加一个隐藏字段来放置正确标识问题的标识符或其他内容。
• 在主页上，您可以使用转发器控件，也可以使用数据动态添加用户控件。
• 检查正确选择的所有代码都应该在用户控件中。
• 在主窗体中，当提交主窗体时，访问每个用户控件并收集结果。

几年前，我在ASP.NET webForms中做了一个类似的应用，但我有"<< Back“和"Next >>”按钮，所以在一个页面上只显示一个问题，整个应用记录时间，所以当测试持续时间过去时，它会将用户带到结束页面。
