如何在C＃中使用sevenzipsharper压缩PDF文件？

Question

I can compress a directory using the following code:

string dll = @"D:\7z.dll";
string source = @"D:\sample";
string output = @"D:\My7zipped.7z";
SevenZipBase.SetLibraryPath(dll);
SevenZipCompressor compressor = new SevenZipCompressor();
compressor.ZipEncryptionMethod = ZipEncryptionMethod.Aes256;
compressor.CompressionMethod = CompressionMethod.Lzma2;
compressor.CompressionLevel = CompressionLevel.Normal;
compressor.CompressDirectory(source, output);

But i want to compress into a single PDF file. How can I compress into a single PDF file?

Answer 1

Use the SevenZipCompressor.CompressFiles method instead of SevenZipCompressor.CompressDirectory .

Please try to find out the basics (like this) yourself. You are supposed to do some work on your own before asking here.

Answer 2

SevenZipCompressor tmp = new SevenZipCompressor(); tmp.CompressStream(File.OpenRead(sourceFile), File.Create(destinationFile));

There is an example on CodeProject of someone creating a C# interface for 7z using the SDK.
