Pass a string from managed C # to managed C ++

Question

what is the preferred method to pass a string between C ++ and C #?

I have a C ++ class where one of the functions takes a parameter char const * const.

how can i call this function in c #? just using C # - stringdoes not seem to work, since a function in C # requiressbyte*

C ++ Class:

public ref class MyClass
{
public:
    void Sample(char const * const Name);
}

Error 2 Argument '1': cannot convert from 'string' to 'sbyte *'

thanks!

Answer 1

If you use managed C ++, you can use the System.String class

Answer 2

You need to try pouring your parameter in C # as sbyte.

Sample((sbyte)nameOfParameter);

.

Answer 3

IMO the best way would be to write a wrapper in C ++ / CLI that uses Marshal::StringToHGlobalAnsior something like that to convert the System :: String ^ pointer to char and call this wrapper from C #.
