Answer 1

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();
}
