Compressing a folder in c# ??

[Eternal]

Hello All,

I am trying to compress a folder with different kinds of files and sub-folder programmaticall y. Googleing all the c# forums and news groups
(almost for half a day ) lead me to ICSharpCode SharpZipLib project. But I dont want to use this and I am trying to find out any other way to do this. Can anyone shed some light on this. I thought it must be easy to compress a folder in c#. Thank you.

.NET framework has two classes that you can use for this
DeflateStream class (without CRC): DeflateStream Class (System.IO.Comp ression)
GZipStream (with CRC): GZipStream Class (System.IO.Comp ression)

Thanks SvenV. Can you give me some example for compressing a folder.

Thanks SvenV. Can you give me some example for compressing a folder.

Did you follow the links that SvenV provided? There is sample code there for compressing files including a link to a full blown application sample, also with source code that is capable of compressing multiple files.

You could also use WMI to do so... Win32_Directory class
System.Manageme nt.

string filePath = @"C:\Zp1\Zp";
            try
            {
                ManagementObject dir =
                    new ManagementObject("root\\CIMV2",  "Win32_Directory.Name='"+filePath+"'", null);
ManagementBaseObject op = dir.InvokeMethod("Compress", null, null);

Console.WriteLine(op["ReturnValue"].Tostring);
//0 for success

Win32_Directory

There is a good open-source library which offers better compression compared to System.IO.Compr ession classes:

.NET Zip Library #ziplib (SharpZipLib)

There are several compression types (Zip, GZip, BZip2, Tar), with adjustable compression settings.

Thank you all for the help.
