Load Array in Blazor

Question

I cloned this app from GitHub, I want to enhance it , if user answers any question incorrectly , I want to display that question ant the end , where the total points scored and total answers are displayed .

For that I am planning to load failed questions into any array , but I am getting an error , how do I load failedquestions[failedIndex] and display the same once the quiz is completed

Code from QuizCardBase.cs

  protected void OptionSelected(string option)
        {
            if (option == Questions[questionIndex].Answer)
            {
                score++;
            }
            { //failedquestions[failedIndex] = Questions[questionIndex].QuestionTitle;
              //  failedIndex++;


            }
            questionIndex++;
        }

Hi @Kalyan A,

You could try below code:

private string[] failedQuestions;
private int failedIndex;

public QuizCardBase()
{
    failedQuestions = new string[100];
    failedIndex = 0;
}

protected void OptionSelected(string option)
{
    if (option == Questions[questionIndex].Answer)
    {
        score++;
    }
    else
    {
        failedQuestions[failedIndex] = Questions[questionIndex].QuestionTitle;
        failedIndex++;
    }
    questionIndex++;
}

protected void DisplayFailedQuestions()
{
    for (int i = 0; i < failedIndex; i++)
    {
        Console.WriteLine(failedQuestions[i]); 
    }
}
