Question

There are mentioned conversions between System::String and const char* in this article.

My question is: Is it possible to make conversion from System::String to char*(note on missing const) with this construction(marshal_context)?

And if not what is recommended solution of this problem?

Am I forced to use older Marshal::StringToHGlobalAnsi?

There is also additional question in comments.

You can obtain the underlying c-style string by using c_str(), a method provided by Strings. It’s const, but you can just copy it away into your own, variable char*.

Just allocate a buffer big enough, like you would with malloc, and then strncpy into it. There’s a hundred different ways of doing this, but it all boils down to reserve memory, copy the string, have fun with it.
