WPF使用XAML图像源

我试图用XamlReader在Image.Source中显示我的矢量图像。我有这样的XAML资源。WPF使用XAML图像源

<Canvas Width="76" Height="76" ClipToBounds="True" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"> 
<Path Fill="#FF000000" Height="76" Stretch="Fill" Width="76"> 
    <Path.Data> 
     <PathGeometry FillRule="Nonzero" Figures="M21,30.0001L55.9999,30.0001 55.9999,50 21,50 21,30.0001z M52,28L37,28C38,25,39.4999,24.0001,39.4999,24.0001L50.75,24C51.3023,24,52,24.6977,52,25.25L52,28z" /> 
    </Path.Data> 
</Path>

创建从here的结合。

<Image Stretch="Fill" Source="{Binding Converter={StaticResource uriToUIElementConverter},ConverterParameter=images/Folder.xaml}"/>

该文件的属性Build Action=Resource：可是，当我尝试用用它不起作用。该转换器uriTOUIElementConverter是：

public class FileToUIElementConverter :IValueConverter 
{ 
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
    { 
     FileStream fileStream = new FileStream((string)parameter, FileMode.Open); 
     return XamlReader.Load(fileStream) as DrawingImage; 
    } 

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
    { 
     throw new NotImplementedException(); 
    } 
}

当我尝试建立项目它给了我这些错误：

System.IO.FileNotFoundException

我编辑器这样的：

Stream fileStream = Application.GetResourceStream(new Uri("pack://application:,,,/ASSEMBLYNAME;component/"+(string) parameter)).Stream;

但它不工作再次。我该怎么做才能使它工作？

您需要提供的路径Application.GetResourceStream与应用程序包有关。

实施例：

我有XAML文件图像/ Folder.xaml。 Folder.xaml的构建操作是资源。

Folder.xaml

<DrawingImage xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"> 
    <DrawingImage.Drawing> 
     <GeometryDrawing Brush="LimeGreen"> 
      <GeometryDrawing.Geometry> 

       <PathGeometry FillRule="Nonzero" 
           Figures="M21,30.0001L55.9999,30.0001 55.9999,50 21,50 21,30.0001z M52,28L37,28C38,25,39.4999,24.0001,39.4999,24.0001L50.75,24C51.3023,24,52,24.6977,52,25.25L52,28z" /> 

      </GeometryDrawing.Geometry> 
     </GeometryDrawing> 
    </DrawingImage.Drawing> 
</DrawingImage>

转换器：

public class FileToUIElementConverter : IValueConverter 
{ 
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
    { 
     string path = parameter.ToString(); 

     StreamResourceInfo sri = Application.GetResourceStream(new Uri(path, UriKind.Relative)); 
     if (sri != null) 
     { 
      using (Stream stream = sri.Stream) 
      { 
       var logo = XamlReader.Load(stream) as DrawingImage; 

       if (logo != null) 
       { 
        return logo; 
       } 
      } 
     } 

     throw new Exception("Resource not found"); 
    } 

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
    { 
     throw new NotImplementedException(); 
    } 
}

用法：

<Image x:Name="ImageLogo" Source="{Binding Converter={StaticResource FileToUiElementConverter}, ConverterParameter=images/folder.xaml}"/>
