String in MC++

[Piecu]

Hello.
I have some class written in C++ and I'm trying to use it in C#. So I've
created new Managed C++ Library in Visual Studio .NET and copied that
code there. But one method takes one parameter of type char*. When I'm
trying to use it in C#, calling it with some string, the compiler gives
some errors. I was also trying to change this char* to String, but the
errors were very similar. Is there any way to do this???

the problem maybe is that the call of your method have a
pointer, char * , and need to be in 'unsafe' block of
code. if you write
unsafe{
myfunction(ref mystring);

}

maybe works. remember to configure in the C# proyect
properties to accept unsafe blocks of code

If you make the managed code method take a System::String* then in C++ you
can get a wchar_t like this:

System::String* fontName = ....
const wchar_t __pin* szFontName = PtrToStringChars( fontName );
