Create zip file using C#

[Chrisch]

Is there any program in C# to create zip file. I want to write an application in C# .NET 2.0 that allow user to use zip file. The zip file created must able to read any files from archives into memory and create new file. Any recommendations and suggestions are appreciated.

private void zip(string[] args)

{

//Create an zip file to read any file

byte[] emptyzip = new byte[] { 80, 75, 5, 6, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

FileStream fls = File.Create(args[1]);

fls.Write(emptyzip, 0, emptyzip.Length);

fls.Flush();

fls.Close();

fls = null;l

Shell32.ShellClass fs= new Shell32.ShellClass();
Shell32.Folder SrcFlder = fs.NameSpace(args[0]);
Shell32.Folder DestFlder = fs.NameSpace(args[1]);
Shell32.FolderItems items = SrcFlder.Items();
DestFlder.CopyHere(items, 0);
System.Threading.Thread.Sleep(500);
}

string[] ster = new string[2];
ster[0] = zipFolderPath; 
str[1] = _startUpPath + "\\" + "Attachment.zip"; 
zip(ster);

Here is program to create zip file in C#.net :

        FileStream sourceFile = File.OpenRead(@"C:\zip.xml");
        FileStream destFile = File.Create(@"C:\zip.zip");

        GZipStream compStream = new GZipStream(destFile, CompressionMode.Compress);

        try
        {
            int value = sourceFile.ReadByte();
            while (value!= -1)
            {
                compStream.WriteByte((byte)value);
                value = sourceFile.ReadByte();
            }
        }
        finally
        {
            compStream.Dispose();
        }

private void ZipFiles(String[] Files, String Output)
        {
            for (int g = 0; g < Files.Length; g++)
            {
                System.IO.FileStream stream = new System.IO.FileStream("" + g, System.IO.FileMode.Open);
                System.IO.Compression.GZipStream gzip = new System.IO.Compression.GZipStream(stream, System.IO.Compression.CompressionMode.Compress, false);
