Compression

SevenZipCompressor compressor = new SevenZipCompressor(@"PATH_TO_SEVENZIPDLL_\7z.dll",
                                                    @"D:\Temp\Test\test.xml");

compressor.SetCompressionFormat(CompressionFormat.GZip);
compressor.SetCompressionLevel(CompressionLevel.Fast);

compressor.AddFile(@"D:\Temp\Test\test.xml");
compressor.DoCompress();
watch.Stop();

Decompression

SevenZipExtractor extractor = new SevenZipExtractor(@"PATH_TO_SEVENZIPDLL_\7z.dll",
                                                        @"D:\Temp\Test\test.xml.gz");

extractor.SetCompressionFormat(CompressionFormat.GZip);

extractor.ExtractArchive(@"D:\Temp\Test\out");

CPP

Using the library from CPP first you have to specify the include directory to SevenZip source code.

#include <SevenZip/include/SevenZipLibraryManager.h>
#include <SevenZip/include/SevenZipCompressor.h>
#include <SevenZip/include/SevenZipExtractor.h>

After specifing the include path you have to call the SevenZipLibraryManager.

SevenZipLibraryManager *libManager = new SevenZipLibraryManager(LR"(PATH_TO_SEVENZIPDLL_\7z.dll)");

Compression

SevenZipCompressor *compressor = new SevenZipCompressor(*libManager, LR"(D:\Temp\Test\test.xml)");
compressor->SetCompressionFormat(CompressionFormat::GZip);
compressor->SetCompressionLevel(CompressionLevel::Fast);
compressor->AddFile(LR"(D:\Temp\Test\test.xml)");
compressor->DoCompress();

Decompression

SevenZipExtractor *extractor = new SevenZipExtractor(*libManager, LR"(D:\Temp\Test\test.xml.gz)");
extractor->SetCompressionFormat(CompressionFormat::GZip);
extractor->ExtractArchive(LR"(D:\Temp\Test\out)")
