Cannot locate resource
提问by piggy
I don't know exactly if it is a bug but i am getting all the time runtime IOException error saying Cannot locate resource.
我不知道这是否是一个错误，但我一直收到运行时 IOException 错误，提示无法定位资源。
I am loading some images in my app (c#, WPF) in canvas background depends on database state. The problem is, that i cannot load LAST (alphabeting sorted) file. I have for example 15 images in folder. I can load 14 first without problems. But the last one all the time throw exception.
我在画布背景中的应用程序（c#、WPF）中加载一些图像取决于数据库状态。问题是，我无法加载 LAST（按字母排序）文件。例如，我在文件夹中有 15 张图像。我可以毫无问题地先加载 14。但是最后一个一直抛出异常。
I am 100% sure, that i HAVE the image in the folder (see !image-printscreen below). And how i wrote. 14 first i can load without any problem, only the last one throw exception.
我 100% 肯定，我在文件夹中有图像（请参阅下面的 !image-printscreen）。还有我怎么写的。14 第一个我可以正常加载，只有最后一个抛出异常。
Is it a bug in WPF-c# or am I doing something wrong?
这是 WPF-c# 中的错误还是我做错了什么？
code what is throwing exception:
代码抛出异常：
canvas_status.Background = new ImageBrush(new BitmapImage(new Uri(BaseUriHelper.GetBaseUri(this), @"Images\" + statusName + ".png")));
canvas_name.Background = new ImageBrush(new BitmapImage(new Uri(BaseUriHelper.GetBaseUri(this), @"Images\" + statusName + bulheadName + ".png")));
error:
错误：
IOException was unhalded
Cannot locate resource 'view/images/panel_uzavreno_d.png'.
image (for higher resolution click on image right mouse button and click on SHOW IMAGE or something like that):
图像（要获得更高的分辨率，请单击鼠标右键单击图像并单击“显示图像”或类似的东西）：

I've had a similar issue: IOException, cannot locate a png resource which indeed existed in the assembly.
我有一个类似的问题：IOException，找不到确实存在于程序集中的 png 资源。
I found the solution by explicitly specifying the assembly name, even though the caller was in the same assembly as the resource.
我通过显式指定程序集名称找到了解决方案，即使调用者与资源在同一个程序集中。
Here's how it looks with a Pack URI syntax:
以下是 Pack URI 语法的外观：
pack://application:,,,/MyAssemblyName;component/MyResourcesFolder/MyImage.png
(For more about Pack URIs see http://msdn.microsoft.com/en-us/library/aa970069.aspx)
（有关 Pack URI 的更多信息，请参见http://msdn.microsoft.com/en-us/library/aa970069.aspx）
Edit:One more thing I had to do after specifying the assembly name was to Cleanthe project. The problem returns after build but was resolved after cleaning the intermediate products. This is definitely a bug in Visual Studio.
编辑：指定程序集名称后我必须做的另一件事是清理项目。构建后问题再次出现，但在清洁中间产品后已解决。这绝对是 Visual Studio 中的一个错误。

You need to set the build action of the image to the type 'Resource'.
您需要将图像的构建操作设置为“资源”类型。
Right-mouse click on the file >> Properties >> set 'Build Action' to 'Resource'
鼠标右键单击文件>>属性>>将“构建操作”设置为“资源”
