The Archive Entry Was Compressed Using an Unsupported Compression Method

I tried to extract ZIP made by 7z (using Deflate), and my application threw me: Unhandled Exception: System.IO.InvalidDataException: The archive entry was compressed using an unsupported compression method.

However, the files still get extracted. How may I suppress this message?

Oh well, I solved my own problem. Always use the Windows Explorer's Send to compressed (zipped) folder to zip files to be used with .NET's zip extraction.
