我试图在代码中设置WPF图像的源代码。图像作为资源嵌入到项目中。通过查看示例，我提出了下面的代码。由于某种原因，它不工作-图像不显示。
通过调试，我可以看到流包含图像数据。怎么了?
Assembly asm = Assembly.GetExecutingAssembly();
Stream iconStream = asm.GetManifestResourceStream("SomeImage.png");
PngBitmapDecoder iconDecoder = new PngBitmapDecoder(iconStream, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
ImageSource iconSource = iconDecoder.Frames[0];
_icon.Source = iconSource;
图标的定义如下:<Image x:Name="_icon" Width="16" Height="16" />

还有一种更简单的方法。如果图像在XAML中作为资源加载，并且所讨论的代码是该XAML内容的幕后代码:
Uri iconUri = new Uri("pack://application:,,,/ImageNAme.ico", UriKind.RelativeOrAbsolute);
NotifyIcon.Icon = BitmapFrame.Create(iconUri);

将框架放在VisualBrush中:
VisualBrush brush = new VisualBrush { TileMode = TileMode.None };
brush.Visual = frame;
brush.AlignmentX = AlignmentX.Center;
brush.AlignmentY = AlignmentY.Center;
brush.Stretch = Stretch.Uniform;
把VisualBrush放在几何绘图中
GeometryDrawing drawing = new GeometryDrawing();
drawing.Brush = brush;
// Brush this in 1, 1 ratio
RectangleGeometry rect = new RectangleGeometry { Rect = new Rect(0, 0, 1, 1) };
drawing.Geometry = rect;
现在将几何绘图放在DrawingImage中:
new DrawingImage(drawing);
把这个放在你的图片源上，然后是voilà!
你可以做得更简单:
<Image>
<Image.Source>
<BitmapImage UriSource="/yourassembly;component/YourImage.PNG"></BitmapImage>
</Image.Source>
</Image>
在代码中:
BitmapImage image = new BitmapImage { UriSource="/yourassembly;component/YourImage.PNG" };
如果你想把它定位在可执行文件旁边(相对于可执行文件)
img.Source = new BitmapImage(new Uri(AppDomain.CurrentDomain.BaseDirectory + @"\Images\image.jpg", UriKind.Absolute));
您还可以将其缩减为一行。这是我用来设置主窗口图标的代码。它假定.ico文件被标记为Content并被复制到输出目录。
this.Icon = new BitmapImage(new Uri("Icon.ico", UriKind.Relative));
如何从嵌入的资源图标和图像(校正版本的Arcturus)加载图像:
假设您想添加一个带有图像的按钮。你该怎么办?
Add to project folder icons and put image ClickMe.png here In properties of 'ClickMe.png', set 'BuildAction' to 'Resource' Suppose your compiled assembly name is 'Company.ProductAssembly.dll'. Now it's time to load our image in XAML <Button Width="200" Height="70"> <Button.Content> <StackPanel> <Image Width="20" Height="20"> <Image.Source> <BitmapImage UriSource="/Company.ProductAssembly;component/Icons/ClickMe.png"></BitmapImage> </Image.Source> </Image> <TextBlock HorizontalAlignment="Center">Click me!</TextBlock> </StackPanel> </Button.Content> </Button>
完成了。
你有没有试过:
Assembly asm = Assembly.GetExecutingAssembly();
Stream iconStream = asm.GetManifestResourceStream("SomeImage.png");
BitmapImage bitmap = new BitmapImage();
bitmap.BeginInit();
bitmap.StreamSource = iconStream;
bitmap.EndInit();
_icon.Source = bitmap;
