C＃/ C ++异步反向pinvoke？(C# / C++ Asynchronous reverse pinvoke?)

 我需要异步调用本机C / C ++ .dll中的C＃代码。 
 
 在搜索如何操作时，我发现我可以创建一个C＃委托并从中获取一个函数指针，我将在我的本机代码中使用它。 
 
 问题是我的本机代码需要异步运行，即在从本机代码创建的单独线程中运行，这意味着从C＃调用的本机代码将在调用委托之前返回到C＃。 
 
 我在另一个SO问题中读到，有人遇到麻烦， 尽管MSDN说的是 ，因为他的委托在被调用之前被垃圾收集，因为他的任务的异步性质。 
 
 我的问题是：使用在本机代码中创建的线程中运行的本机代码中的函数指针调用C＃委托是否真的可行？ 谢谢。 

I need to call C# code from a native C/C++ .dll asynchronously.
 
While searching how to do I found that I could create a C# delegate and get a function pointer from it, which I would use inside my native code.
 
The problem is that my native code needs to run asynchronously, i.e in a separate thread created from the native code, which means that the native code called from the C# will return to C# before the delegate is called.
 
I read in another SO question that someone had trouble with this, despite what the MSDN says, because his delegate was garbage collected before it gets called, due to the asynchronous nature of his task.
 
My question is : is it really posible to call a C# delegate using a function pointer from a native code running in a thread that was created inside the native code ? Thank you.
