Practical experience in using Sharpzip compression and decompression

First, in the http://www.icsharpcode.net/OpenSource/SharpZipLib/Default.aspx download source, find "ZipConstants.cs" modified
public static string ConvertToString (byte[] data)
{
Return encoding.getencoding ("gb2312"). GetString (data, 0, data.) Length);
Return Encoding.ASCII.GetString (data,0, data. Length);
}

public static byte[] Converttoarray (String str)
{
Return encoding.getencoding ("gb2312"). GetBytes (str);
return Encoding.ASCII.GetBytes (str);
}
So you can support the Chinese name.
Here's what I wrote about the compression and decompression code:
Using System;
Using System.Collections;
Using System.ComponentModel;
Using System.Data;
Using System.Drawing;
Using System.Web;
Using System.Web.SessionState;
Using System.Web.UI;
Using System.Web.UI.WebControls;
Using System.Web.UI.HtmlControls;
Using ICSharpCode.SharpZipLib.Zip;
Namespace OA
{
<summary>
Summary description of the WebForm1.
</summary>
public class WebForm1:System.Web.UI.Page
{
public string Serverdir;
private void Page_Load (object sender, System.EventArgs e)
{
Place user code here to initialize page
This. Serverdir = Page.mappath (".");
This. ZipFile ("01.txt*02.txt*000.zip"); Just examples, the specific people to achieve
This. ZipFile ("01.txt*02.txt*001.zip");
This. Unzipfile ("000.zip*001.zip");
}
public string Shortdir (string s)
{
To convert a file's absolute path to a relative path
String D=s.replace (Serverdir, "");
return D;
}
Compressed file p Returns a list of files for the client: filename + name of the compressed package
public void ZipFile (string p)
