Searching for compression library in c# that supports rar format

Question

I want to add in my application functionality to decompress (and optionally compress) files in various format. I have libraries that supports zip, gzip, 7zip and bzip2. But still not found library that support rar.
I know that rar is commercial, but maybe there is some .net library that could be used to decompress rar-s? The best would be free library, but library with small price is also acceptable.

Answer 1

Try SevenZipSharp. It supports extraction of RAR files and everything else that 7-zip supports.
