To further simplify interop with unmanaged code, you can create small wrapper classes in Visual C++ that hide all of the code needed to call the functions. By doing so, you reap the potential benefits of using C++ Interop while allowing easy access to the wrapper from other managed languages (C# and Visual Basic .NET).

One of the primary differences between C++ Interop and standard PInvoke (using the DllImport attribute) is that you are responsible for marshaling parameters when using C++ Interop. In the AddSomeNumbers function example, the code to use C++ Interop is simple. We don t need any special marshaling code because the data types involved are blittable. This means they are represented the same way in the managed and unmanaged code, and conversion of data is not necessary. On the other hand, if the function requires non-blittable types, you are required to handle the marshaling duties yourself, converting the input parameters prior to the call and the result upon conclusion of the call. To illustrate the differences between C++ Interop and PInvoke, the following code executes two unmanaged functions, AddSomeNumbers and CombineStringsW. For comparison purposes, each function is called via PInvoke and C++ Interop. This example also demonstrates the concept of developing a small wrapper class in Visual C++ and using it from other managed languages like C# and Visual Basic .NET. The unmanaged C++ functions for this test are defined like this: extern "C" __declspec(dllexport) int __stdcall AddSomeNumbers(int numOne, int numTwo); extern "C" __declspec(dllexport) void __cdecl CombineStringsW(wchar_t* stringA, wchar_t* stringB, wchar_t* result); And implemented like this: int __stdcall AddSomeNumbers(int numOne, int numTwo) { return numOne + numTwo; } void __cdecl CombineStringsW(wchar_t* stringA, wchar_t* stringB, wchar_t* result) { int bufLength = (int)wcslen(stringA) + (int)wcslen(stringB) + 100; wchar_t* tempResult = new wchar_t[bufLength]; wcscpy_s(tempResult, bufLength, stringA); wcscat_s(tempResult, bufLength, stringB); wcscat_s(tempResult, bufLength, L" Another Unicode String "); wcscat_s(tempResult, bufLength, L"Unicode"); wcscpy_s(result, bufLength, tempResult); delete [] tempResult; }
