C# Emgu CV无法加载DLL'；cvextern&x27；在部署的项目中

我在ASP.NET项目中使用EmguCV进行人脸检测。当我从VisualStudio运行项目时，一切正常

然后我通过文件夹配置文件发布了发布版本，然后将发布的版本上传到smarterasp.net

应用程序一般都在运行。但当应用程序尝试检测图像中的人脸时，会抛出一个异常：

System.AggregateException: One or more errors occurred. ---> System.TypeInitializationException: The type initializer for 'Emgu.CV.CvInvoke' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'cvextern': The specified module could not be found.

也许这就是原因？为什么在部署的应用程序中有我的本地路径

---

我以前从未部署过一个项目，所以100%是因为我犯了一些愚蠢的错误。我做错了什么？

简单的答案是，无论您的exe文件在哪里，EmguCV DLL和OpenCV DLL的所有都必须被删除。开发过程中发生的事情与部署完全没有关系

我发现将EmguCV DLL与我的EXE放在一个文件夹中很方便，并将所有OpenCV DLL放在一个名为x64的文件夹中。x64文件夹也与exe位于同一文件夹中
