I am trying to compile a project that was previous using /oldsyntax, but now with /clr.

std::string Jhc::Interop::stlString(System::String^ s)
{
    std::string out;
    const wchar_t __pin * str = PtrToStringChars(s);
    int len = s->Length*4;
    char *buf = new char[len];
    memset(buf,len,0);

I have changed System::String *s to System::String^ s, but how do I covert the line with PtrToStringChars(s);?

I have tried using pin_ptr and interior_ptr, but cannot make it work.

Could you please show the compile error? – KimKulling Mar 23 '17 at 10:22
Maybe you want to turn it into a `std::wstring` instead? If not, then you need to do a locale conversion from wide-characters to UTF8. – paddy Mar 23 '17 at 10:26

I think I have solved it by using : pin_ptr str = PtrToStringChars(s); – Alf Inge Mar 23 '17 at 16:08
