    C# String conversion

    Hi, I'm having some difficulty converting a String to a std::basic_stri ng
    (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::Clien t::initialize(c lass std::basic_stri ng<unsigned
    short,struct std::char_trait s<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.
