Download the standalone console version from 7zip.com and add it to your project.

You need those 3 Files added in the project:

1. 7za.exe
2. 7za.dll
3. 7zxa.dll

Don't forget to say Copy to Output Directory in it's preferences.

Extract an archive:

public void ExtractFile(string sourceArchive, string destination)     {         string zPath = "7za.exe"; //add to proj and set CopyToOuputDir         try         {             ProcessStartInfo pro = new ProcessStartInfo();             pro.WindowStyle = ProcessWindowStyle.Hidden;             pro.FileName = zPath;             pro.Arguments = string.Format("x \"{0}\" -y -o\"{1}\"", sourceArchive, destination);             Process x = Process.Start(pro);             x.WaitForExit();         }         catch (System.Exception Ex) {             //handle error         }     } 

Create an archive:

public void CreateZip(string sourceName, string targetArchive) {     ProcessStartInfo p = new ProcessStartInfo();     p.FileName = "7za.exe";     p.Arguments = string.Format("a -tgzip \"{0}\" \"{1}\" -mx=9", targetArchive, sourceName);     p.WindowStyle = ProcessWindowStyle.Hidden;     Process x = Process.Start(p);     x.WaitForExit(); }

The authors of 7zip provide the LZMA SDK and good documentation which should be able to achieve what you want. The SDK includes C# code capable of compression / decompression.

Another option would be to use a something like C# (.NET) Interface for 7-Zip Archive DLLs

UPDATE: Another user asked a similar question here: How do I create 7-Zip archives with .NET? The answer has several of the same links I provided and a few more.

It doesn't look like this library supports encrypted files. No method takes a key as a parameter.

回答4:

The 7zSharp library doesn't seem to support password as input, just a zip file.

The library just calls the .exe of 7zip, so you could donwload the source and alter it to accept a password parameter which you then pass to the executable.
