Hi,

   I had made an application in mfc .net 2005 and after compiling i got the dll, now i want to import those dll in c# to make the application in it. In the methods defined in dll we have user defined refernce arguments like

BOOL call(Income &,const Interestrate &);

I need to call these functions in c#.
I tried to import dll and define function like this:

using System.Runtime.InteropServices;

public classMyapp
{
  [DllImport ("Income",EntryPoint="Incomerate")]
        public static extern bool Incomerate(Income &,const Interestrate &);
}

But I'm getting error Identifier expected;

please help.
