Zip folder in C#

Question

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

---

Update:

I do not see namespace ICSharpCode. I downloaded ICSharpCode.SharpZipLib.dll 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.

OK, but I need next information.

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

This answer changes with .NET 4.5. Creating a zip file becomes incredibly easy. No third-party libraries will be required.

string startPath = @"c:examplestart";
string zipPath = @"c:example
esult.zip";
string extractPath = @"c:exampleextract";

ZipFile.CreateFromDirectory(startPath, zipPath);
ZipFile.ExtractToDirectory(zipPath, extractPath);
