我想要一个解决方案：请确保该文件是可访问的，它是一个有效的程序集或COM组件 [英] I want a solution for this : Please make sure that the file is accessible and that it is a valid assembly or COM component

问题描述

我正在C＃中使用OpenCV构建一个项目。它需要一个名为 cvextern.dll 的dll文件。但是，当添加此文件作为参考时，会显示以下消息： -

无法添加cvextern.dll引用，请确保该文件是可访问的，它是一个有效的程序集或COM组件。

我从搜索中累了，我花了过去2天来搜索解决方案

解决方案

该文件是本机DLL，这意味着您无法通过添加将它添加到.NET项目参考...您可以通过DllImport使用它（请参阅 http ：//msdn.microsoft.com/en-us/library/system.runtime.interopservices.dllimportattribute.aspx ）

I am building a project with OpenCV in C#. It requires a dll file called cvextern.dll. but, when adding this file as a reference, this message appears :-

a reference "cvextern.dll" can't be added, Please make sure that the file is accessible and that it is a valid assembly or COM component.

I get tired from searching, I spent the past 2 days in searching for a solution for that problem

解决方案

the file is a native DLL which means you can't add it to a .NET project via Add Reference... you can use it via DllImport (see http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.dllimportattribute.aspx)
