C＃：添加DLL参考

Question

Preface: I know basically nothing about C#. I've added a dll to my project. I have no build errors, but when I try to run, I get an error that says it can't find the dll. I've tried copying it to the output directories too. To no avail.

Any idea what could be happening?

Specific Error:

System.IO.FileNotFoundException was unhandled Message=Could not load file or assembly 'controllib_clr.dll' or one of its dependencies. The specified module could not be found. Source=controllib_demo_cs...

I'll be happy to add more information if need be. :) I just don't know what info would be beneficial given my (very) limited knowledge.

Answer 1

看来它无法找到/加载一些依赖项dll，我将使用DependencyWalker找出丢失的内容http://www.dependencywalker.com/

Answer 2

If it exists, in your output folder, then most likely its one of its dependencies that is missing. You can fix this by adding its dependencies as references in your project.

if it doesn't exist in your output, then, check that "Copy Local" is set in the properties of the reference.

Answer 3

Is it a managed (.NET) or an unmanaged (native) DLL? I'm assuming unmanaged.

FileNotFoundException is commonly thrown when missing a dependency. The DLL you are loading might require any number of other DLLs on load. In most cases it won't tell you which file it needs. You have to refer to the documentation for that DLL.
