C#/XAML ajouter une image de bouton

Je suis en début de programme dans Windows Phone 8 avec C#/XAML. Actuellement, je suis l'élaboration d'un questionnaire de type app WP8 qui a une question (textblock) et 4 options (sous la forme de boutons). Ce que j'aime faire, c'est, pour afficher les images de ces options dans les boutons. Comment vais-je faire?

S'il vous plaît ne vérifier ce que j'ai commencé
c'est mon entrée de données de la classe:

    class DataEntry
{
    List<DataModel> dataModelList = new List<DataModel>();
    public List<DataModel> GetData()
    {
        dataModelList.Add(new DataModel { ID = 0, Question = "A major", Answer1 = "chords/g_major.gif", Answer2 = "chords/c_major.gif", Answer3 = "chords/b_major.gif", CorrectAnswer = "chords/a_major.gif" });
        dataModelList.Add(new DataModel { ID = 1, Question = "B major", Answer1 = "chords/g_major.gif", Answer2 = "chords/d_major.gif", Answer3 = "chords/e_major.gif", CorrectAnswer = "chords/b_major.gif" });
    }
}

Et ma classe MainPage:

public partial class MainPage : PhoneApplicationPage
{
List<DataModel> dataModelList = new List<DataModel>();
List<ScoreModel> scoreModelList = new List<ScoreModel>();
Random rand = new Random();
DataEntry dataEntry = new DataEntry();
int number1, number2, number3, number4, score = 0, scoreToHave = 4;
string CorrectAnswer;
int QuestionID = 0;
public MainPage()
{
InitializeComponent();
dataModelList = dataEntry.GetData();
Question();
}
private void Question()
{
foreach (var item in dataModelList)
{
if (item.ID == QuestionID)
{
TextBlock_Question.Text = item.Question;
CorrectAnswer = item.CorrectAnswer;
RandomAnswerPlaces(item.Answer1, item.Answer2, item.Answer3, item.CorrectAnswer);
}
}
}
public void RandomAnswerPlaces(string Answer1, string Answer2, string Answer3, string Answer4)
{
String[] Answers = new string[4];
noRepeat();
Answers[number1] = Answer1;
Answers[number2] = Answer2;
Answers[number3] = Answer3;
Answers[number4] = Answer4;
btnAnswer1.Content = Answers[0];
btnAnswer2.Content = Answers[1];
btnAnswer3.Content = Answers[2];
btnAnswer4.Content = Answers[3];
}
private void noRepeat()
{
number1 = rand.Next(0, 4);
number2 = rand.Next(0, 4);
number3 = rand.Next(0, 4);
number4 = rand.Next(0, 4);
if (number1 == number2 ||
number1 == number3 ||
number1 == number4 ||
number2 == number3 ||
number2 == number4 ||
number3 == number4)
{
noRepeat();
}
}
private void btnStartGame(object sender, RoutedEventArgs e)
{
Canvas_StartGame.Visibility = System.Windows.Visibility.Collapsed;
Canvas_Game.Visibility = System.Windows.Visibility.Visible;
}
private void Button_AnswerClick(object sender, RoutedEventArgs e)
{
string ClickedAnswer = ((System.Windows.Controls.Button)(sender)).Content.ToString();
string ClickedButtonName = ((System.Windows.Controls.Button)(sender)).Name.ToString();
switch (ClickedButtonName)
{
case "btnAnswer1":
btnAnswer1.IsEnabled = false;
break;
case "btnAnswer2":
btnAnswer2.IsEnabled = false;
break;
case "btnAnswer3":
btnAnswer3.IsEnabled = false;
break;
case "btnAnswer4":
btnAnswer4.IsEnabled = false;
break;
default:
break;
}
if (CorrectAnswer == ClickedAnswer)
{
if (QuestionID < (dataModelList.Count() - 1))
{
QuestionID++;
}
else
{
MessageBox.Show(string.Format("Game Over! your final score : {0}", score));
SaveHighScore();
}
score += scoreToHave;
scoreToHave = 5;
Question();
btnAnswer1.IsEnabled = true;
btnAnswer2.IsEnabled = true;
btnAnswer3.IsEnabled = true;
btnAnswer4.IsEnabled = true;
}
else
{
scoreToHave -= 2;
}
TextBlock_ScoreToHave.Text = string.Format("Score you can get: {0}", scoreToHave.ToString());
TextBlock_Score.Text = string.Format("Score: {0}", score.ToString());
}
private void SaveHighScore()
{
if (IsolatedStorageSettings.ApplicationSettings.Contains("scoreList"))
{
scoreModelList = IsolatedStorageSettings.ApplicationSettings["scoreList"] as List<ScoreModel>;
scoreModelList.Add(new ScoreModel { Score = score, DateSaved = DateTime.Now.ToShortDateString() });
IsolatedStorageSettings.ApplicationSettings.Clear();
IsolatedStorageSettings.ApplicationSettings.Add("scoreList", scoreModelList);
IsolatedStorageSettings.ApplicationSettings.Save();
}
Canvas_StartGame.Visibility = System.Windows.Visibility.Collapsed;
Canvas_Game.Visibility = System.Windows.Visibility.Collapsed;
Canvas_HighScore.Visibility = System.Windows.Visibility.Visible;
var tempList =
from item in scoreModelList
where item.Score > 0
orderby item.Score descending
select string.Format("Date: {0} Score: {1}", item.DateSaved, item.Score);
ListBox_HighScore.ItemsSource = tempList.ToList();
score = 0;
scoreToHave = 5;
QuestionID = 0;
Canvas_StartGame.Visibility = System.Windows.Visibility.Visible;
Canvas_Game.Visibility = System.Windows.Visibility.Collapsed;
}
private void Button_DoneClick(object sender, RoutedEventArgs e)
{
Canvas_StartGame.Visibility = System.Windows.Visibility.Visible;
Canvas_Game.Visibility = System.Windows.Visibility.Collapsed;
Canvas_HighScore.Visibility = System.Windows.Visibility.Collapsed;
}
}

Et le fragment de mon xaml:

<Canvas Name="Canvas_Game" 
VerticalAlignment="Center"
HorizontalAlignment="Center" 
Height="800" Width="480"
Visibility="Collapsed">
<!--Visibility="Collapsed">-->
<Grid  Height="800" Width="480">
<StackPanel VerticalAlignment="Center" HorizontalAlignment="Center">
<TextBlock Name="TextBlock_ScoreToHave" Text="Score to have:"/>
<TextBlock Name="TextBlock_Score" Text="Score:"/>
<TextBlock Width="480" Text="Question:" FontSize="40"/>
<TextBlock VerticalAlignment="Top" Name="TextBlock_Question" Text="What is the meaning of life?" FontSize="32" Width="480" TextAlignment="Left" TextWrapping="Wrap" MaxHeight="400"/>
<Button Name="btnAnswer1"  Content="Answer1" Click="Button_AnswerClick"/>
<Image Source="/chords/"></Image>
<Button Name="btnAnswer2"  Content="Answer2" Click="Button_AnswerClick"/>
<Button Name="btnAnswer3"  Content="Answer3" Click="Button_AnswerClick"/>
<Button Name="btnAnswer4"  Content="Answer4" Click="Button_AnswerClick"/>
</StackPanel>
</Grid>
</Canvas>

Comme vous pouvez le voir, ce que j'ai accompli jusqu'à présent est que c'est uniquement l'affichage des chaînes de caractères (les réponses) dans le bouton. Je voudrais savoir comment faire pour afficher ses images que j'ai appelé de mes accords de dossier. Toute aide est appréciée. Merci.
