C# & SharpzipLib : How to put each file in a directory in their own zip file.
1:54 PM 0 Comments

I needed to zip every file in a folder into their own zip files. After a while on Google I finally decided to code it for myself. So here is a method you can use to do this, just pass in two paths and your good to go. Download SharpZipLib Here:(http://www.icsharpcode.net/OpenSource/SharpZipLib/Download.aspx)

<br />
using System;
using System.IO;
using ICSharpCode.SharpZipLib.Zip;
class MainClass
{
 public static void Main(string[] args)
 {
        ZipEachFileInDirectory(@"C:\FilesToZip\",
            @"C:\ZippedFiles\");
 }

/// <summary>
    /// This will compress all the files in a folder into
    /// their own zip files. Instead of putting all files in a zip file.
    /// </summary>
    /// <param name="sourceFolder">The folder path that contains the files to zip.</param>
    /// <param name="destFolder">The folder path you want the zip files created.</param>
    private static void ZipEachFileInDirectory(string sourceFolder, string destFolder)
    {

try
        {

string[] filenames = Directory.GetFiles(sourceFolder);

foreach (string file in filenames)
            {
                using (ZipOutputStream s = 
                    new ZipOutputStream(
                        File.Create(destFolder + 
                           Path.GetFileNameWithoutExtension(file) + ".zip")))
                {

s.SetLevel(9); // 0 - store only to 9 - means best compression

byte[] buffer = new byte[4096];
                    ZipEntry entry = new ZipEntry(Path.GetFileName(file));
                    entry.DateTime = DateTime.Now;
                    s.PutNextEntry(entry);
                    using (FileStream fs = File.OpenRead(file))
                    {
                        int sourceBytes;
                        do
                        {
                            sourceBytes = fs.Read(buffer, 0, buffer.Length);
                            s.Write(buffer, 0, sourceBytes);
                        } while (sourceBytes > 0);
                    }
                    s.Finish();
                    s.Close();// Close is important to wrap things up and unlock the file.
                }
            }
        }
        catch (Exception ex)
        {
            //Console.WriteLine("Exception during processing {0}", ex);
            // No need to rethrow the exception as for our purposes its handled.
        }
    }
}
