c# - C#如何存储值并检查数据库？

Question

我正在从数据库中做随机问题，但现在我想存储值和问题 ID 并检查数据库查看天气答案是否正确？单击提交按钮后，如何存储单选按钮和文本框中的值？

这是我对随机问题的编码

public void showquestion()
{
    string Category = "10-20";

    string query = "SELECT top 10 * FROM question where Age_group= '"+ Category +"' order by newid()";
    if (question.OpenConnection() == true)
    {
        SqlCommand comm = new SqlCommand(query, question.connection);
        question.rdr = comm.ExecuteReader();
        while (question.rdr.Read())
        {
            for (int j = 0; j < 1; j++)

                    cell.Controls.Add(label);
                    row.Cells.Add(cell);

像这样创建一个静态类：

public class MySession
{
    public static MySession Instance
    {
        // this is the element you store the question and answer in by using MySession.Instance.QnsAndAnswer.Add(qnID, ansId);
        public Dictionary<QuestionID, AnswerID> QnsAndAnswers { get; set; }

        get 
        {
            MySession session = (MySession)HttpContext.Current.Session["__MySession__"];

            if (session == null)
            {
                session = new MySession();
                HttpContext.Current.Session["__MySession__"] = session;
            }
            return session;
        }
    }
}
