Randomly assign the contents of a Button

I'm creating a quiz for kids in WPF.

All the questions are coming from a database.

The interface has a textblock for the question and four buttons for the multiple choice answers.

How do I randomly assign the Content of the buttons so that the correct answer isn't in the same button all the time?

You could use a method to shuffle the answers:

  List<string> Shuffle(List<string> answers)
    {
        Random r = new Random();
        Dictionary<int, string> d = new Dictionary<int, string>();
        foreach (var answer in answers)
        {
            d.Add(r.Next(), answer);
        }
        return d.OrderBy(a => a.Key).Select(b => b.Value).ToList();
    }

Essentially you could do this by just generating a random number between 0 and 3 as your location of your correct answer. Then display the rest of the answers in whatever order they come form the database.

To get the random number you can use:

var placeHolder = new Random().Next(0,3);
