c# - 图片来源 UriKind

Question

我有一个项目，它的名字是'xx'。我创建了一个具有以下路径的文件夹“images”：xx\bin\Debug\images\

images 只包含一张照片，它的名字是“1.jpg” MainWindow 包含 Image 控件；我将此代码设置为加载图像源，但它不起作用为什么？？：

private void Image_MouseDown(object sender, MouseButtonEventArgs e)
{
    Image i = sender as Image; ;
    BitmapImage b = new BitmapImage(new Uri(@"images\1.jpg",UriKind.Relative));
    i.Source=b;
}

如何通过代码加载图像源？提前致谢 ：）

Answer 1

您需要添加1.jpg到images文件夹中的项目并将 Properties1.jpg设置为Resource。要加载资源，请使用packURI约定。

private void Image_MouseDown(object sender, MouseButtonEventArgs e)
{
    Image i = sender as Image; ;
    BitmapImage b = new BitmapImage(new Uri(@"pack://application:,,,/" 
         + Assembly.GetExecutingAssembly().GetName().Name 
         + ";component/" 
         + "Images/1.jpg", UriKind.Absolute)); 
    i.Source=b;
}

尝试这个

public void Image_MouseDown(object sender, RoutedEventArgs e)
{
    OpenFileDialog dlg = new OpenFileDialog();
    dlg.InitialDirectory = "c:\\";
    dlg.Filter = "Image files (*.jpg)|*.jpg|All Files (*.*)|*.*";
    dlg.RestoreDirectory = true;
    Nullable<bool> result = dlg.ShowDialog();                        

    if (result == true)
    {
        BitmapImage bitmap = new BitmapImage();
        Image img = sender as Image;
        bitmap.BeginInit();
        bitmap.UriSource = new Uri(dlg.FileName);
        bitmap.EndInit();
        img.Source = bitmap;
    }
}
