Marshaling return value I also have a C++ library (without managed extensions). A function returns a char*. I want to call this function from C#. How can I access the char*? I tried to use byte[] or char[] but I am having a problem because as soon as I call my C++ function, I get an exception thrown with a message "Cannot marshal return value". Here is the code that calls C++ function byte[] charAr = new byte[41]; charAr = Region.RegionMgr_GetStateAbbrev(80);
