You need to add the dll file as a reference in your project. Right click on References in the Solution Explorer->Add Reference->Browse and then select the dll.

Finally you'll need to add it as a using statement in whatever files you want to use it in.

Or if you want to add more folders without need to open and close archive multiple times:

<pre><code>using Rebex.IO.Compression;
...

// open the ZIP archive from an existing file 
ZipArchive zip = new ZipArchive(@"C:\archive.zip", ArchiveOpenMode.OpenOrCreate);

// add first folder
zip.Add(@"c:\first\folder\*","\first\folder");

You can <a href="http://www.rebex.net/zip.net/download.aspx" rel="nofollow noreferrer">download the ZIP component here</a>.

Using a free, LGPL licensed <a href="http://www.icsharpcode.net/opensource/sharpziplib/" rel="nofollow noreferrer">SharpZipLib</a> is a common alternative.

In .NET 4.5 the ZipFile.CreateFromDirectory(startPath, zipPath); method does not cover a scenario where you wish to zip a number of files and sub-folders without having to put them within a folder. This is valid when you wish the unzip to put the files directly within the current folder.

This code worked for me:

<pre><code>public static class FileExtensions
{
 public static IEnumerable&lt;FileSystemInfo&gt; AllFilesAndFolders(this DirectoryInfo dir)
 {
 foreach (var f in dir.GetFiles())
 yield return f;
 foreach (var d in dir.GetDirectories())
 {
 yield return d;
 foreach (var o in AllFilesAndFolders(d))
 yield return o;
 }
 }
}

void Test()
{
 DirectoryInfo from = new DirectoryInfo(@"C:\Test");
 using (FileStream zipToOpen = new FileStream(@"Test.zip", FileMode.Create))
 {
 using (ZipArchive archive = new ZipArchive(zipToOpen, ZipArchiveMode.Create))
 {
 foreach (FileInfo file in from.AllFilesAndFolders().Where(o =&gt; o is FileInfo).Cast&lt;FileInfo&gt;())
 {
 var relPath = file.FullName.Substring(from.FullName.Length+1);
 ZipArchiveEntry readmeEntry = archive.CreateEntryFromFile(file.FullName, relPath);
 }
 }
 }
}
</code></pre>

Folders don't need to be "created" in the zip-archive. The second parameter "entryName" in CreateEntryFromFile should be a relative path, and when unpacking the zip-file the directories of the relative paths will be detected and created.

What is an example (simple code) of how to zip a folder in C#?

<hr>

Update:

I do not see namespace <code>ICSharpCode</code>. I downloaded <code>ICSharpCode.SharpZipLib.dll</code> but I do not know where to copy that DLL file. What do I need to do to see this namespace?

And do you have link for that MSDN example for compress folder, because I read all MSDN but I couldn't find anything.

<hr>

OK, but I need next information.

Where should I copy <code>ICSharpCode.SharpZipLib.dll</code> to see that namespace in Visual Studio?

在C#中如何压缩文件夹的示例(简单代码)是什么？更新：我没有看到命名空间ICSharpCode。我下载了ICSharpCode.SharpZipLib.dll，但我不知道将该DLL文件复制到哪里。我需要做什么才能看到这个命名空间？你有关于压缩文件夹的MSDN例子的链接吗，因为我读了所有的MSDN，但是我什么也找不到。好...
