How to pass strings from C++ to C#

Here is what I am trying to do:

I have a C# application that contains an unmanaged C++ project.  The C++ project is responsble for collecting messages from a "server" via ethernet then firing an event so that the C# knows that there is a new message. Then the C# reads the message.  

I have the event working, but I am seeing issues with getting the string to the C# code.  In the C++ dll the message is available as a wstring.  What is the best way to do this?

This method probably would be the easiest approach: http://www.codeproject.com/KB/cs/wm_copydata_use.aspx ("Use WM_COPYDATA to send data to/from C++ and C# Windows processes")
