I think the following article can fulfill your requirement

C# Zip Files and/or Folders

protected void btnZip_Click(object sender, EventArgs e)
    {
        StringBuilder sb = new StringBuilder(); 	//  Builder to save report
        string ZipFileName = String.Format(@"C:\ZippedFolders\({0}).MyZip.zip",
		DateTime.Now.ToString("yyyyMMdd")); 	//  Zip Destiny File Name
        string theDirectory = @"C:\FolderToZip";    	//  Folder to zip

        try
        {
            sb.Append(String.Format("Directory To Zip: {0}.<br/>", theDirectory));
            sb.Append(String.Format("Zip file: {0}.<br/>", ZipFileName));

            string[] allFiles = Directory.GetFiles(theDirectory, "*.*",
		SearchOption.AllDirectories);   	// Get all files from
						// the folder to zip

            if (System.IO.File.Exists(ZipFileName)) 	//  Small piece of code
					// to delete zip file if it already exists
            {
                System.IO.File.Delete(ZipFileName);
                sb.Append(String.Format
		("Deleted old Zip file: {0}.<br/>", ZipFileName));
            }

            //  J# code to zip

            FileOutputStream fos = new FileOutputStream(ZipFileName); //  J# output
							      // stream (Zip File)
            ZipOutputStream zos = new ZipOutputStream(fos);           //  J# output zip
            zos.setLevel(9);    //  Set the level of compression.
				// It may be a value between 0 and 9

            /*
                Add each file from folder to zip, to zip file.
                This way, the tree of the folder to zip will be
                reflected on the zip file
            */

            for (int i = 0; i < allFiles.Length; i++ )
            {
                string sourceFile = allFiles[i];

                FileInputStream fis = new FileInputStream(sourceFile);  //  J# input
							//stream to fill zip file
                /*
                    Add the entry to the zip file (The Replace will remove the full path
                    Ex.: file C:\FolderToZip\Files\Tmp\myFile.xml,
		  will be written as Files\Tmp\myFile.xml on the zip file
                    If this code was not written, it would generate the
		  whole tree since the beginning of the FolderToZip
                    This way the zip file begins directly at the contents
		  of C:\FolderToZip
                */

                ZipEntry ze = new ZipEntry(sourceFile.Replace(theDirectory + @"\", ""));
                zos.putNextEntry(ze);

                sbyte[] buffer = new sbyte[1024];
                int len;

                while ((len = fis.read(buffer)) >= 0)
                {
                    zos.write(buffer, 0, len);  //  Write buffer to Zip File
                }

                fis.close();    //  Close input Stream
            }

            //  Close outputs
            zos.closeEntry();
            zos.close();
            fos.close();

            sb.Append(String.Format("Folder {0} Zipped successfully to File {1}.<br/>",
						theDirectory, ZipFileName));

        }
        catch (Exception eX)
        {
            sb.Append(String.Format("Error zipping folder {0}. Details: {1}.
		Stack Trace: {2}.<br/>", theDirectory, eX.Message, eX.StackTrace));
        }

        lbReport.Text = sb.ToString();  //  Show result/report
    }

Hi Akash,

first you have to understand, that GZipStream is not creating ZIP files at all. It just compresses a stream of data. (A Zip-File is more because a ZIP file also is a container for multiple files and directories). So I fear you cannot create a ZIP file just with GZipStream.

You could use ZipPackage to create a ZIP file. Just have a look at http://msdn.microsoft.com/en-us/library/system.io.packaging.zippackage.aspx for more details.

Maybe you want to think about the requirement to not use any 3rd party libraries. There are some nice libraries e.g. the SharpZipLib: http://www.icsharpcode.net/opensource/sharpziplib/

With kind regards,
