C# String conversion

[Neomite]

Hi, I'm having some difficulty converting a String to a std::basic_string
(c++).

I've tried using StringBuilder and Marshal.LPxxxx , no luck.

I consistently get AccessViolation errors.

I've been reading all day but I can't seem to find the same problem posted
anywhere.

bool NNSMCAPI::Client::initialize(class std::basic_string<unsigned
short,struct std::char_traits<unsigned short>,class std::allocator<unsigned
short> > const &)

Can anyone help me with this issue?

thanks!

It wont work becuase Marshal.LPxxxx does not convert to basic_string, but
only gets you a pointer to the raw string charcters in memory.

You can try using a wrapper around your function which takes LPTSTR, this
way you can use Marshal.LPxxxx

I read a few similiar posts that talked about using StringBuilder? Are you
familiar with this approach?

Yes, but that works only if data flow is from called function to yourself.
In this case, if i understand correctly, its the other way round.
