In this course, we will create a desktop application using C# and Windows Form in Visual Studio. The application we will be making is a quiz maker application that will allow you to create a multiple-choice quiz. You can upload an image per question, add the question and answers. We will be using radio buttons to select the correct answer from the list of questions. Once you’ve created a question, you can then save that question to the program and create a new question. You can also save the question as a text file to the computer, load it up later to add more questions, update the questions, or delete any question. All of this will be done inside the application. We will also be performing exception handling in the program to solve the problem of files not being in the right format or empty file detection.

We will also create the play quiz window with this program. In this window, you will be able to load the quiz text file you have created and play the quiz. In this window, you will be able to randomize the questions for the quiz, where it will shuffle all the questions from the text file and randomly display them in the quiz. When the quiz starts, it will have a time limit per question, and it will automatically move to the next question if it has not been answered. At the end of the quiz, it will show a Q and A window that will contain the results of the quiz. It will show how many questions were answered correctly and show the answers for questions answered incorrectly. The program will keep track of all the questions from the text file.

Quiz Maker Window –

1. Using object-oriented programming to create a questions class and organize the questions using it.
