Question

您好我正在尝试使用asp.net构建一个非常基本的测验应用程序。我有一个带有字符串数组和字符串答案的测验类。然后我尝试创建一个新的测验对象并向数组添加四个问题。将它们添加到会话中并显示在标签中的另一页上。

按钮点击

    protected void Unnamed8_Click(object sender, EventArgs e)
    {
        Quiz one = new Quiz();
        one.answer = "First";
        one.questions[0] = "First";
        one.questions[1] = "Second";
        one.questions[2] = "Third";
        one.questions[3] = "Fourth";

        Session["Thequiz"] = one;
        Response.Redirect("WebForm1.aspx");
    }

测验课

    public class Quiz
    {
        public string[] questions; 
        public string answer { get; set; }

        public Quiz()
        {
            questions = new string[] {"First","Second","Third","Fourth"};
        }
    }

Display.aspx尝试删除数组的第一个元素并将其添加到标签

   namespace Quiz
   {
        public partial class WebForm1 : System.Web.UI.Page
        {
           Quiz was;
           protected void Page_Load(object sender, EventArgs e)
           {

             was = (Quiz)Session["Thequiz"];
              was.answer = (string)display.Text;
           }
        }
   }

标签是空白的，只是想知道原因。

Answer 1

您可以反转标签和分配值。

 display.Text = was.answer;

尝试使用字符串数组构建一个类
