Questioncalling a method in c++ from c# [modified] Pinmemberbonosa12-Feb-13 17:45 
this is in my c++ file
 
public ref class Class1
    {
    public:
        int read_file
        (const char * file_path,    /* Path to  file */
         hdf_call_vars_t & ret_vals)    ;
 

 

 
    };
 
and from c# I call it like so (unsafe code)
 
    hdf_call_vars_t ret_vals;
 
            string str = "C:\\a.h5";
            byte[] bytes = Encoding.ASCII.GetBytes(str);
 

 
                fixed (byte* p = bytes)
                {
                    sbyte* sp = (sbyte*)p;
                    
                    DoAT.Class1 cl = new DoAT.Class1();
 
                    cl.read_file(sp,  ref ret_vals);
 
It does not compile sayiing the c++ is expecting a pointer to a structure. I thought making it an & is the same as passing by ref?
Input appreciated.
thanks,
sb
 
p.s. the c++ is a managed dll and I add it as a reference in the c# program.
