I am using a C# DLL in my C++ code (Visual Studio 2010). How do I convert a System::String^ to a C++ std::string?

System.Runtime.InteropServices.Marshal has several methods that convert a string to an array of characters, which you could then use any manner of methods to get a std::string.

I believe the recommendation is to use StringToBSTR eventually calling FreeBSTR once you have copied the data to a different object.

The question I linked to as a comment recommends StringToCoTaskMemUni.
