asp.net2.0下，如何实现服务器端压缩包自解压

using System;

using System.Data;

using System.Configuration;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using System.IO;

using System.IO.Compression;

/// <summary>

/// ZipUtility 的摘要说明

/// </summary>

public class ZipUtility

{

public ZipUtility()

{

// TODO: 在此处添加构造函数逻辑

}

public static void Compress(Stream source, Stream destination)

{

using (GZipStream output = new GZipStream(destination, CompressionMode.Compress))

{

Pump(source, output);

}

public static void Decompress(Stream source, Stream destination)

{

using (GZipStream input = new GZipStream(source, CompressionMode.Decompress))

{

Pump(input, destination);

}

private static void Pump(Stream input, Stream output)

{

byte[] bytes = new byte[4096];

int n;

while ((n = input.Read(bytes, 0, bytes.Length)) != 0)

{

output.Write(bytes, 0, n);

}

简单应用：

protected void Button1_Click(object sender, EventArgs e)

{

FileStream fs=File.OpenWrite("d:/Data.txt");

Stream c=this.FileUpload1.PostedFile.InputStream;

ZipUtility.Decompress(c, fs);

fs.Close();

c.Close();

}
