Question

我在asp中创建了一个多项选择测验，但我的代码很长，你知道如何缩短它。此外，我有每个输入的验证器，但我不知道我怎么能停止提交按钮被点击，除非输入所有的答案。

我的测试代码：

很抱歉这个状态，但我很新，我正在努力学习和编写代码。

您可以使用ListView，GridView等数据控件。那么即使您有100个问题，也不必更改单行代码。

<asp:ListView runat="server" ID="ListView1">
    <ItemTemplate>
        <%# Eval("Question") %>
        <asp:HiddenField runat="server" ID="IdHiddenField" Value='<%# Eval("Id") %>'/>
        <asp:RadioButtonList ID="AnswerRadioButtonList" runat="server"
            RepeatDirection="Horizontal" RepeatLayout="Table">
            <asp:ListItem Text="*Answer 1*" Value="Incorrect 1" />
            <asp:ListItem Text="*Answer 2*" Value="Correct" />
            <asp:ListItem Text="*Answer 3*" Value="I" />
            <asp:ListItem Text="*Answer 4*" Value="4" />
        </asp:RadioButtonList>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
            Display="Dynamic" ControlToValidate="AnswerRadioButtonList"
            ErrorMessage="Ensure question is completed" CssClass="field-validation-error" />
        <hr />
    </ItemTemplate>
</asp:ListView>
<asp:Button ID="Button1" runat="server" Text="Submit Final Answers"
    OnClick="Submit_Click" Visible="true" />

代码背后

public class Quiz
{
    public int Id { get; set; }
    public string Question { get; set; }
    public string Answer { get; set; }
}

public partial class WebForm2 : System.Web.UI.Page
{
    // This could come from database
    private IList<Quiz> Quizzes
    {
        get
        {
            return new List<Quiz>
            {
                new Quiz {Id = 1, Question = "Question 1"},
                new Quiz {Id = 2, Question = "Question 2"},
                new Quiz {Id = 3, Question = "Question 3"},
                new Quiz {Id = 4, Question = "Question 4"},
                new Quiz {Id = 5, Question = "Question 5"}
            };
        }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            ListView1.DataSource = Quizzes;
            ListView1.DataBind();
        }
    }

    protected void Submit_Click(object sender, EventArgs e)
    {
        IList<Quiz> quizzes = new List<Quiz>();
        for (int i = 0, length = Quizzes.Count; i < length; i++)
        {
            ListViewDataItem item = ListView1.Items[i];
            var radioButtonList = item.FindControl("AnswerRadioButtonList") as RadioButtonList;
            var idHiddenField = item.FindControl("IdHiddenField") as HiddenField;
            quizzes.Add(new Quiz
            {
                Id = Convert.ToInt32(idHiddenField.Value),
                Answer = radioButtonList.SelectedValue
            });
        }
    }
}

可以压缩此代码（ASP多项选择测验）
