C# – Free compression library for C# which supports 7zip (LZMA)


I have a program (written in C#) that reads/writes its data directly (direct file access without server) to firebird database files. For a better exchange I want to (un)compress them on import/export for a better exchange over the internet without the need of an external program to (un)compress them.

I know #ziplib which supports Zip, GZip, Tar and BZip2.

What else free compression libraries for C# do you know?
Is there a .NET library which supports LZMA so i can read/write ".7z" files?

Best Solution

7-zip has a free source code, public domain C# SDK for the LZMA algorithm:
