I'm using following solution:
__dllimport on function, i want to use into .NET application.
Than declare static method of class in .NET with atribute
"dllimport(dllname,methodname)" (exact syntax lookup in documentation (such
as msdn)).
I have some troubles with marshaling of string from .net application to C++.
.NET has very strange behaviour with marshaling strings - as i undestood,
NET converts string to ASCII-string, if string doesn't have any symbol with
ASCII-code greater than 127, and to unicode strings in other case.

There are two solutions:
To write COM, COM+, or DCOM component, and use interopt techniques on .NET.
In this case .NET generates interopt's object and .NET class for COM
component opaque.

This means, your task looks like that:
Write dll / COM, than using it as described bellow.

Sorry for my english.
