Question

我有一些c＃的代码，我想通过url在c＃代码中添加一些图片但是没有添加，所以请告诉我这段代码有什么问题。我的项目名称是ProjectDemo，我有保存所有图像的文件夹图像。

 private void Window_Loaded(object sender, RoutedEventArgs e)
    {

        collection = new ObservableCollection<Image> { 
            new Image{ Height=128, Width=128,Source=new BitmapImage(new Uri("/ProjectDemo;component/images/highway.png", UriKind.Relative))} ,
            new Image{Height=128, Width=128,Source=new BitmapImage(new Uri("/ProjectDemo;component/images/highway-1.png", UriKind.Relative))}, 
            new Image{ Height=128, Width=128,Source=new BitmapImage(new Uri("/ProjectDemo/images/part-5.png", UriKind.Relative))} ,
            new Image{Height=128, Width=128,Source=new BitmapImage(new Uri("/ProjectDemo;component/images/part-6.png", UriKind.Relative))} ,
             new Image{ Height=128, Width=128,Source=new BitmapImage(new Uri("/ProjectDemo;component/images/part-7.png", UriKind.Relative))} ,
            new Image{Height=128, Width=128,Source=new BitmapImage(new Uri("/ProjectDemo;component/images/part-8.png", UriKind.Relative))} ,
             new Image{ Height=128, Width=128,Source=new BitmapImage(new Uri("/ProjectDemo;component/images/speed-1.png", UriKind.Relative))} ,
            new Image{Height=128, Width=128,Source=new BitmapImage(new Uri("/ProjectDemo;component/images/speedroad.png", UriKind.Relative))} 
         };
         FirstListBox.Items.Add(collection[0]);
         FirstListBox.Items.Add(collection[1]);
         FirstListBox.Items.Add(collection[2]);
         FirstListBox.Items.Add(collection[3]);
         FirstListBox.Items.Add(collection[4]);
         FirstListBox.Items.Add(collection[5]);
         FirstListBox.Items.Add(collection[6]);
         FirstListBox.Items.Add(collection[7]);

    }

只是一个友好的建议，在编写wpf中的单行代码之前学习MVVM。

首先确保项目中包含图片且BuildAction为"Resource"

然后在你的VM或代码后面你可以做

 public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            InitializeImages();
            DataContext = this;

        }

        private void InitializeImages()
        {
            ImageModels.Add(new ImageModel
            {
                Source = new BitmapImage(new Uri("/ProjectDemo;component/images/highway.png", UriKind.Relative))
            });
            ImageModels.Add(new ImageModel
            {
                Source = new BitmapImage(new Uri("/ProjectDemo;component/images/highway-1.png", UriKind.Relative))
            });
            ImageModels.Add(new ImageModel
            {
                Source = new BitmapImage(new Uri("/ProjectDemo;component/images/part-5.png", UriKind.Relative))
            });
        }


        ObservableCollection<ImageModel> _imageModels = new ObservableCollection<ImageModel>();

        ObservableCollection<ImageModel> ImageModels
        {
            get { return _imageModels; }
        }
    }

    public class ImageModel : INotifyPropertyChanged
    {
        private ImageSource imageSource;

        public ImageSource Source
        {
            get { return imageSource; }
            set
            {
                imageSource = value;
                RaisePropertyChanged("Source");
            }
        }

        private void RaisePropertyChanged(string propName)
        {
            if(PropertyChanged != null)
            {
                PropertyChanged(this,new PropertyChangedEventArgs(propName));
            }
        }


    public event PropertyChangedEventHandler PropertyChanged;
    }

并在View

中

  <ListBox ItemsSource="{Binding ImageModels}">
       <ListBox.ItemTemplate>
            <DataTemplate>
                <Image Height="128" Width="128" Source="{Binding Source}"></Image>
            </DataTemplate>
       </ListBox.ItemTemplate>
   </ListBox>

你可以试试这个：

Source = new BitmapImage(new Uri(@"pack://application:,,,/ProjectDemo;component/images/highway.png"));
