如何从非托管代码中调用托管代码？ [英] How to call managed code from unmanaged code?

问题描述

我想从非托管C ++调用.NET代码。我的流程入口点是基于.NET的，因此我不必担心托管CLR。我知道可以使用.NET对象的COM包装器来完成此操作，但是我想访问托管类的各个静态方法，因此COM不是我最短/最简单的方法。

I want to call my .NET code from unmanaged C++. My process entrypoint is .NET based, so I don't have to worry about hosting the CLR. I know it can be done using COM wrappers for .NET objects, but I would like to access individual static methods of managed classes, so COM isn't my shortest/easiest route.

推荐答案

假定您正在谈论真正的非托管代码-不仅仅是运行在使用/ clr编译的混合模式程序集中的本机C ++-最简单的方法是为.NET创建包装器C ++ / CLI中的代码。然后，您可以通过仅用__declspec（dllexport）标记C ++ / CLI方法来导出它们。

Assuming you are talking about real unmanaged code - not just native C++ running in a mixed-mode assembly compiled with /clr - the easiest way is to create a wrapper to your .NET code in C++/CLI. You can then export the C++/CLI methods by just marking them with __declspec(dllexport).

或者，如果您可以控制非托管代码的调用，则可以将功能指针编组到您的.NET方法，并将它们传递给非托管代码。

Alternatively, if you have control over the invocation of the unmanaged code, you can marshal function-pointers to your .NET methods and pass them to the unmanaged code.
