Solution

  • UnRAR.dll is not a .NET assembly so it cannot be used as a project reference.

    It is a native DLL so you'll have to use P/Invoke to access its methods or write a C++/CLI wrapper around it.

    There's some sample code in this MSDN forum thread that should provide a decent starting place and show the necessary approach.

    There also appears to be a fairly complete wrapper included in the Blue Mirror CD/DVD Indexer project.

    It should also be noted the SevenZipSharp includes support for this out-of-the-box. I haven't used it myself, but it might be worth checking into.
