Question

So I have a function in unmanaged c++ that gets called when some text happens to have “arrived”:

#using <MyParser.dll>
...
void dump_body(const unsigned char *Body, int BodyLen) 
{
  // Need to pass the body to DumpBody, but as what type?
     ...
  MyParser::Parser::DumpBody(???);
}

DumpBody is a static function defined in a C# DLL that should take one parameter of type?

Body holds an array of characters (text) of length BodyLen.

There’s obviously some marshalling to be done here but I have no idea how.

Please help.

Answer 1

void dump_body(const unsigned char *body, int bodyLen)
{
    // you might want a different encoding...
    String ^str = gcnew String((sbyte*)body, 0, bodyLen, gcnew ASCIIEncoding);
    MyParser::Parser::DumpBody(str);
}

DumpBody will take a string.
