在与主项目不同的库中使用资源映像 [英] Using a resource image in a library different from the main project

问题描述

我有一个带有两个库的WPF程序

I have a WPF program with two libraries

现在内部，我在主程序和HelperLib中都具有灰色资源背景。但是另外，在HelperLib中，我想使用红色背景。

now inside I have a gray resource background both in the main program and HelperLib. But additionally in the HelperLib I have a red background I want to use.

现在，当我想使用以下方式更改窗口的背景时：

Now when I want to change the background of a window with:

 switch (bubbleType)
  {
    case eBubbleType.ERROR:
      bw.btText.Background = new ImageBrush(new BitmapImage(new Uri("pack://application:,,,/Resources/Images/gradientWallpaper_RED.jpg"))); <-----I want to use this one 
      break;

    default:
      bw.btText.Background = new ImageBrush(new BitmapImage(new Uri("pack://application:,,,/Resources/Images/gradientWallpaper.jpg")));
      break;
  }

但我在RED图像上却找不到图像，但在另一个。
我怀疑使用灰度渐变时，它不是在lib中使用而是在主程序中使用，因为我看到资源与程序集无关，而与项目无关。
这两个图像都具有与图片相同的属性：

but I get an image not found exception on the RED image but not on the other one. I suspect that, when using the gray gradient it's not using the one in the lib but the one in the main program since I see that the resource is related to the assembly not to the project. Both images have the same properties as in picture:

推荐答案

您必须使用资源文件包Uri ，其中包含所引用程序集的名称：

You would have to use a Resource File Pack Uri with the name of the referenced assembly:

new Uri(
  "pack://application:,,,/HelperLib;component/Resources/Images/gradientWallpaper_RED.jpg")
