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" />

Force选择UriKind将是正确的:
Image.Source = new BitmapImage(new Uri("Resources/processed.png", UriKind.Relative));
UriKind可选:
UriKind.Relative // relative path
UriKind.Absolute // exactly path
其他回答
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));
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" };
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;
很简单:
要动态设置菜单项的图像，只需执行以下操作:
MyMenuItem.ImageSource =
new BitmapImage(new Uri("Resource/icon.ico",UriKind.Relative));
.．.而“icon.ico”可以位于任何地方(目前它位于“资源”目录中)，并且必须链接为资源…
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。
