从Go语言调用C＃DLL（类库）函数 [英] C# DLL (Class Library) functions called from Go Language
问题描述
Hello Go Lang和C＃专家，
Hello Go Lang and C# gurus,
美好的一天。
我想问一下是否有人尝试过从Go程序中调用C＃DLL函数（类库类型）？
Good day. I would like to ask if anyone of you have tried calling a C# DLL functions (Class Library type) from a Go program?
我做了一些初始的研究并看到以下文章：
I have made some initial research and saw these articles:
- https://github.com/golang/go/wiki/WindowsDLLs
- https://stackoverflow.com/questions/27849137/golang-call-windows-dll-functions
但是这些是从C Win32实现中创建的DLL。
我尝试搜索加载到Go程序中的C＃DLL，所有这些都会告诉您在Go程序上调用它之前，您需要具有C ++ / C（Win32）包装器。
But these are DLLs created out from C Win32 implementations. I tried searching for C# DLL loaded into Go program all of them will tell you that you need to have a C++/C (Win32) wrapper before you can call it on a Go program.
此外，上面的链接将告诉您Go期待我认为的 C声明（类型为__declspec）或类似内容（例如WINAPI）。
Plus, the links above will tell you that Go is expecting a "C" declaration I think (which is of type __declspec) or the likes (e.g. WINAPI).
在这种情况下是否可以完全跳过C / C ++包装器并直接在Go中调用C＃DLL函数？
Is there a way in this case where we can completely skip the C/C++ wrapper and directly call the C# DLL functions in Go?
您的
谢谢
推荐答案
选项1 将您的.NET DLL转换为COM组件，例如，然后您可以按照您的第一个链接。请记住，该选项仅适用于Windows。
Option 1 Turn your .NET DLL into a COM component like this, then you can invoke it from golang following the steps in your first link. Remember this option is for windows only.
选项2 将DLL包装在一个简单的C＃控制台应用程序中，然后使用< a href = https://golang.org/pkg/os/exec/ rel = nofollow noreferrer> os / exec 。如果您的C＃DLL是跨平台的，那么您的最终程序仍然是跨平台的。
Option 2 Wrap the DLL within a simple C# console application, and invoke the application in golang using os/exec. Your final program is still cross-platform if your C# DLL is cross-platform.
两个选项都需要C＃的基本知识，或者创建COM组件，或者编写控制台。应用程序来调用DLL。 IMO后者更容易。
Both options need a basic knowledge of C#, either creating COM components, or writing a console application to invoke the DLL. IMO the latter is easier.
