Does anyone noe how to zip a directory using the ICSharpCode.SharpZipLib dll ?

Answer 2

Define a new ZipEntry using the root folder

and recursive loop the folder and file under the folder and add it to the ZipOutputStream

public void ZipFolder(string RootFolder, string CurrentFolder, ZipOutputStream zStream)
{
 string[] SubFolders = System.IO.Directory.GetDirectories(CurrentFolder);
 foreach (string Folder in SubFolder)
 {
  ZipFolder(RootFolder, Folder, zStream);
 }

 ZipEntry entry;
 entry = new ZipEntry(CurrentFolder.Substring(RootFolder.Length) + "/");
 entry.DateTime = DateTime.Now;

 zStream.PutNextEntry(entry);

 //Start loop files under CurrentFolder
 //End
}

Hi jacky, thanks for the example,however, are you using the ICSharpCode dll or the java.util.zip ?

Another question, when i intially call the method ? Do I pass in the root folders into the method ?>

Answer 4

I'm using ICSharpCode.SharpZipLib.dll

when i intially call the method?
just call the function when you want to zip folder, the function will loop to get all folders and files inside the root folder where you pass in.
P.S. you need to declare the ZipOutputStream before call the method.

Do I pass in the root folders into the method?
yes, just call

ZipOutputStream s = new ZipOutputStream(SomewhereYouWantToZip);
s.SetLevel(6); // 0 - store only to 9 - means best compression
ZipFolder(SomewhereYouWantToZip, SomewhereYouWantToZip, s);

hope it can help you.

Answer 5

What happens if at the end of the basecase i need to zip additional files ??

given the structure

Pictures/Family/25102005_Outing.jpg
Pictures/Family/26102005_BBQ.jpg

What i want to achieve is 1 zip file created and the final Family folder has the 2 photos.

Answer 6

FYI.

string SomewhereYouWantToZip = "Pictures";

ZipOutputStream s = new ZipOutputStream(SomewhereYouWantToZip);
s.SetLevel(6); // 0 - store only to 9 - means best compression
ZipFolder(SomewhereYouWantToZip, SomewhereYouWantToZip, s);

Sorry Jacky,

however the ZipOutPutStream() requires a System.IO.Stream path to be passed in and not a string.

Answer 8

sorry, the thing should be.

string SomewhereYouWantToZip = "Pictures";
string TheZipFilePath = "Somewhere";

ZipOutputStream s = new ZipOutputStream(File.Create(TheZipFilePath));
s.SetLevel(6); // 0 - store only to 9 - means best compression
ZipFolder(SomewhereYouWantToZip, SomewhereYouWantToZip, s);

Sorry for the mistake...

Actually, if you are using ICSharpCode.SharpZipLib you can download the sample in their website, there has a sample project called CreateZipFile, you can reference that project. and just modify the zip file part to the code what I post before.
