Delegate from C++ to C#

I have an application in managed C++, and a method in C# that I call. But now
I want to add the ability to tell the C# method a specific method in my C++
assembly to call back to. For example, to have the C++ call a sort routine in
C#, and send it a compare method, which the C## would call back to. I know
that within C# pointing to methods is done with delegates, but is it possible
between C++ and C#? Is there an example of this somewhere that anyone knows
of? Thanks for any help you can provide.
 
Thank you. The second article looks perfect, I will see what I can do with it.

Just a note to follow up in case anyone has a similar problem, I was able to
make a C++ program with a method in it, then call a C# function, sending in
the delegate to the method, and the C# called back to the C++ method.

Thanks again for the help.
