Hi!
I used below code for quiz its worked, but I have problem with timer for one question need 1 minuts.
By default rdOption must be not choosed when I choosed for first question answer and go to second question then first answer choosed show on next its must be not choosed for each question.
namespace QuesQuiz
{
public partial class Quiz : Form
{
public int i;
static int index = 0;
static int correct = 0;
static string answer = "";
public struct Question { public string question; }
public struct Option { public string optOne, optTwo, optThree, optFour, optFive; }
public Quiz()
{
InitializeComponent();
timer_quiz.Enabled = false;
timer_quiz.Interval = 6000;
i = 5;
grpBox.Visible = false;
}
private void btnStart_Click(object sender, EventArgs e)
{
timer_quiz.Start();
GenerateQuestionsOptions(index);
lblAnswer.Visible = false;
grpBox.Visible = true;
}
public void GenerateQuestionsOptions(int index)
{
// Question based on Index
Question question = new Question();
question.question = PopulateQuestions().Rows[index]["QuestionDescription"].ToString();
// Options based on Question
Option options = new Option();
options.optOne = PopulateQuestions().Rows[index]["OptionOne"].ToString();
options.optTwo = PopulateQuestions().Rows[index]["OptionTwo"].ToString();
options.optThree = PopulateQuestions().Rows[index]["OptionThree"].ToString();
options.optFour = PopulateQuestions().Rows[index]["OptionFour"].ToString();
options.optFive = PopulateQuestions().Rows[index]["OptionFive"].ToString();
// Answer based on Question
answer = PopulateCorrectAnswer(PopulateQuestions().Rows[index]["QuestionDescription"].ToString());
// Adding options to List for shuffling options
List<string> optionsList = new List<string>();
optionsList.Add(options.optOne);
optionsList.Add(options.optTwo);

// Shuffle options List
List<string> shuffledOptions = optionsList.OrderBy(a => Guid.NewGuid()).ToList();
//List<string> shuffledOptions = RandomizeList(optionsList);
// Assigning question and options
lblQuestion.Text = (index + 1) + " : " + question.question.ToUpper();
rbOptionOne.Text = shuffledOptions[0];
rbOptionTwo.Text = shuffledOptions[1];
