C# Array problem

Hi, I busing make a c# Quiz game for my project, but im having problems with the arrays. I'm using a textfile to read all the question and options into labels and into radio buttons. I have a button to start the quiz en a button "Next"button to display the question 2 that is in the same text file and also must be displayed in the same labels and the radio buttons. My problem is how do I display the question on the same labels with the radio buttons and also if the user clicks next to store his option in a array and then the next question must display. If anyone can give a guide I will be very thankful.
