如何使用从非托管code管理code？ [英] How to use managed code from unmanaged code?

问题描述

我如何打电话从本机C ++（非托管code）一种.NET code？我要揭露​​.NET code到我的非托管（C ++）应用程序，然后使用它们。更具体地讲，我想打电话给C＃从本地C ++ :)。我知道有很多方法，但你能告诉我每一个优点和缺点？顺便说一句，我不希望使用COM那么什么是选择现在？

How do I call a .NET code from native C++ (unmanaged code)? I want to expose .NET code to my unmanaged (C++) application and then use them. More specifically, I want to call C# from native C++ :). I know there are many ways but can you tell me the pros and cons of each? By the way, I don't want to use COM so what are the options now?

难道我换用C ++ / CLI的C＃code，然后从C ++调用它呢？如果是这样，我怎么做呢？我该如何包装在C ++ / CLI的C＃，然后从C调用它++？

Is it possible that I wrap the C# code in C++/CLI and then call it from C++? If so, how do I do that? How do I wrap the C# in C++/CLI and then call it from C++?

推荐答案

我已经写了这件事刚刚结束。这是德尔福，但这并不意味着它不会用C ++工作也。

I've written about it just recently. It was about Delp but that doesn't mean it won't work with C++ as well.

即使不知道很多关于C ++，我还是知道++（的情况下，你需要传递的对象，而不仅仅是结构）IUnknown和COM兼容接口引用应该是可用的从C就好了。

Even without knowing much about C++, I still know that IUnknown and COM-compatible interface references should be usable just fine from C++ (in the case you need to pass objects, not just structures).

• 您可以使用微软的Visual C ++ / CLI参考你的C＃code，并将其导出为普通的DLL函数。
• 您也可以下载 MSBuild任务我写的，这可以让你直接导出功能从C＃。类似于如何DllImportAttribute被使用。

• You can use Microsoft's C++/CLI to reference your C# code and export it as ordinary DLL functions.
• You can also download an MSBuild task I wrote, that allows you to export function directly from C#. Analogous to how DllImportAttribute is used.

本C＃code将导出功能YourExportName，可用于就像任何C兼容的功能将被使用。

This C# code would export a function "YourExportName" that can be used just like any c-compatible function would be used.

class Sample
{
   [DllExport("YourExportName")]
   static int TestFunction(int left, int right)
   {
     return left + right;
   }
}
