我開始使用C＃/ XAML編程Windows Phone 8。目前我正在開發一個有問題（textblock）和4個選項（以按鈕形式）的測驗類型WP8應用程序。我想要做的是在按鈕中顯示這些選項的圖像。我該怎麼做？C＃/ XAML將圖像添加到按鈕
請你檢查什麼我已經開始 這是我的DataEntry類：
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" });
}
}
我的MainPage類：
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;
}
}
我的XAML的片段：
<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>
正如你所看到的，到目前爲止我所完成的是它只是在按鈕中顯示字符串（答案）。我想知道如何顯示我從我的和絃文件夾中調用的圖像。任何幫助表示讚賞。謝謝。
你正在分配一個字符串按鈕Content屬性，你應該創建一個圖像控件的實例（我不知道Windows Phone 8的名稱空間，谷歌它），並將其分配給按鈕的內容。 – BenCr
