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;

这是一个更少的代码,可以在一行中完成。

string packUri = "pack://application:,,,/AssemblyName;component/Images/icon.png";
_image.Source = new ImageSourceConverter().ConvertFromString(packUri) as ImageSource;

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));

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

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。
