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" />

如果你的图像存储在ResourceDictionary中，你只需要一行代码就可以做到:
MyImage.Source = MyImage.FindResource("MyImageKeyDictionary") as ImageSource;

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" };
你只是漏了一点。
要从任何程序集获取嵌入式资源，你必须像我在这里提到的那样，用你的文件名提到程序集名称:
Assembly asm = Assembly.GetExecutingAssembly();
Stream iconStream = asm.GetManifestResourceStream(asm.GetName().Name + "." + "Desert.jpg");
BitmapImage bitmap = new BitmapImage();
bitmap.BeginInit();
bitmap.StreamSource = iconStream;
bitmap.EndInit();
image1.Source = bitmap;
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;
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));
这是我的方式:
internal static class ResourceAccessor
{
public static Uri Get(string resourcePath)
{
var uri = string.Format(
"pack://application:,,,/{0};component/{1}"
, Assembly.GetExecutingAssembly().GetName().Name
, resourcePath
);
return new Uri(uri);
}
}
用法:
new BitmapImage(ResourceAccessor.Get("Images/1.png"))
