How to Extract folders from ZIP?

[twas brillig]

I'm using .NET 4.5 which has ZIP abilities built in.

Say my project is structured like this:

├── ListOfFolders.zip (Locked with password)
       └── FolderA
       └── FolderB
       └── FolderC
└── Hack.exe (Allows you to choose where to install certain folders that are inside the zip)

The user runs Hack.exe and selects:

1. Which folders he wants
2. Where to extract the selected folders

Would someone be willing to help with this? This would be a useful function to share if I could have some help writing it.

.NET 4.5 Documentation. Doesn't achieve what I'm trying to do.

 

using System;
using System****;
using System****.Compression;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string zipPath = @"c:\example\start.zip";
            string extractPath = @"c:\example\extract";

            using (ZipArchive archive = ZipFile.OpenRead(zipPath))
            {
                foreach (ZipArchiveEntry entry in archive.Entries)
                {
                    if (entry.FullName.EndsWith(".txt", StringComparison.OrdinalIgnoreCase))
                    {
                        entry.ExtractToFile(Path.Combine(extractPath, entry.FullName));
                    }
                }
            } 
        }
    }
}

Those of you that are helping me, be sure to reference

Try this. I'm sure there are better ways of doing it, but it works for me..

 public static void extractDir(string directoryName, string zipPath, string extractPath)
        {

            //Open Zip Archive
            using (ZipArchive archive = ZipFile.OpenRead(zipPath))
            {
                //For each file in archive
                foreach (ZipArchiveEntry entry in archive.Entries)
                {
                    //If Directory name equals directoryName          Splitting the Directory path, to get the first directory name of the path
                    //Console.WriteLine(Path.GetDirectoryName(entry.FullName));
                    if (Path.GetDirectoryName(entry.FullName).Split('/')[0].Equals(directoryName) || Path.GetDirectoryName(entry.FullName).Split('\\')[0].Equals(directoryName))
                    {
                        //Combine the destination path
                        string combinedPath = Path.Combine(extractPath, Path.GetDirectoryName(entry.FullName));
                        //Create directory(s)
                        if (!Directory.Exists(combinedPath))
                        {
                            Directory.CreateDirectory(combinedPath);
                        }

                        //Check if the entry is a directory
                        if (!Directory.Exists(Path.Combine(combinedPath, entry.Name)))
                        {
                            entry.ExtractToFile(Path.Combine(combinedPath, entry.Name));
                        }
                    }

                }
            }
        }

A function call would look like this:

extractDir("FolderInZipFileToExtract","Zipfile.zip ","DestinationPath");

The Structure inside the folder to extract is kept the same.
